       What Does DRS do?

         DRS reads BAD disks!  If you have a disk that returns
         GENERAL FAILURE READING DRIVE X.  DRS will read it anyway.
         DRS will even read a disk that you poke a whole in.  Of
         course you can not read the data in the bad area but
         you can recover the rest.  You will mark the areas you
         want to recover and then save those marked areas in files
         you name.  You will instruct DRS where to put these
         files, on another floppy or your hard drive.

         You may also instruct DRS to simply print out your
         marked areas.

         How safe is DRS?  If it reads BAD disks then it can also
         write on them.  DRS is SAFE!  It does not write to logical
         sectors anywhere, it only reads.  The files you declare
         and save are normal DOS files with your own names.  If
         it is possible to write on a bad disk why did I not give
         you this ability?  Because DRS is an entry level recovery
         package.  Had a casual user accidentally told DRS to
         save data at a logical sector on the hard drive they
         could wipe out their FAT table etc.  It is very easy
         to adapt DRS to write on and therefor possibly repair
         bad disks but that would have to be a future professional
         release.

    INTRODUCTION


    DRS is a RAM-based disk reader that offers a wealth
    of  features  designed to make the program powerful yet extremely
    easy to learn and use. DRS offers  users a choice of using
    a sliding menu or quick F key hit for all of the major program
    functions.

    DRS has a very short learning curve.  DRS's logical, easy
    to use, easy to learn structure is the result of setting up
    a software package in a logical use sequence.  You will be
    utilizing and running with DRS in no time. If you are new
    to data recovery you will be surprised at how easy DRS is to
    use and how quickly you'll be able to learn all the advanced
    features of DRS.

    Data Research is also determined to be a leader in Customer
    Support.  We offer telephone support and a 24-hour Bulletin Board
    for online support at any time.  We also listen to our users. Many
    suggestions from earlier Shareware versions of DRS have been
    incorporated into this latest release.  Two of the very next
    items to be incorporated will be IDE, SCSI support and BINARY
    trace and recovery.  Both are items suggested from DRS Shareware
    users.

    GETTING STARTED

    DRS requires an IBM PC or close compatible with 256K, two disk
    drives or hard drive a color/graphics or monochrome card and
    monitor (VGA, EGA, CGA or MONO), and a printer.  Before you start
    using DRS, you should  be  familiar with your computer. You need
    to know how to load DOS, how to make a copy of a diskette, and
    how to load and run a program.  DRS was designed to be visible
    on Color or Monochrome without any installation.  So many features
    were thought of during the creation of this first commercial
    release that I am sure you will see new releases in the future.

    The DRS Program Disk

    Your DRS program disk includes the following files:

      DRS.EXE      The main program file.

      DRS.DOC      This File

      READ.ME      Last minute changes and updates

      HIST.DRS     List of changes to DRS

      INSTALL.EXE  Install program, sets color, printer port, etc.

    You  should  make  a backup copy of your DRS program disk, and
    store the original in a safe  place.   Never  use  your  original
    DRS program disk as your working copy.


   Data Recovery Reference   Page  7

    SETTING UP DRS

    Floppy Disk System:

        1.   With  your computer turned off, open the door
             to Drive A, and insert your DOS disk.

        2.   Close the door to Drive A  and  turn  on  your
             computer.

        3.   If DOS asks you for the date, enter the date in the
             following format: mm-dd-yy, or mm/dd/yy, and  then
             press Enter.

        4.   If  DOS asks you for the time, enter the time
             in the following format: 8:30 or 20:30,  and  then
             press Enter.

        5.   When A> appears on the screen, remove the DOS
             disk from Drive A and insert your working copy  of
             the  DRS Program Disk, and close the disk drive
             door.  Type "INSTALL".


   Hard Disk System:


        1.   Turn on your computer  with  the  floppy  disk
             drive empty.

        2.   If  DOS asks you for the date, enter the date
             in the following format:  mm-dd-yy,  or  mm/dd/yy,
             and then press Enter.

        3.   If  DOS asks you for the time, enter the time
             in the following format: 8:30 or 20:30,  and  then
             press Enter.

        4.   When  C>  appears  on the screen, insert your
             working copy of the DRS program disk in Drive A
             and close the disk drive door.

        5.  Type "INSTALL".

        6.  After you install DRS change to the DRS sub-directory
            by typing CD\DRS.

        7.  Type "DRS" to start the program.


   Data Recovery Reference   Page  8



    STARTING DRS



    Floppy Disk System:


        1.   After starting  your  computer,  type  A:  and
             press Enter if you don't see the DOS prompt, A>.

        2.   Insert the copy of the installed DRS program disk
             in Drive A.  Type DRS and then press Enter.


   Hard Disk System:


        1.   After starting your computer,  type  CD  and  then
             type  the  name  of  the directory you copied your
             DRS files to with INSTALL. For example, if  the
             directory  is called Text, you would type CD\TEXT.
             Then press Enter.

        2.   Type DRS and then press Enter.

        3.   On a Hard Disk System, you can  use  the  DOS Path
             command to start DRS from any DOS prompt.
             For more information  on  the  DOS  Path  command,
             consult your DOS manual.

    The  DRS  opening  screen  will  appear  after  the program is
    loaded. Please read the opening screen.  The opening screen
    will provide information concerning how to contact technical
    support, the distributor, etc. Now, simply press any key to
    continue.

    The next screen you see will be the main sliding menu.  This is
    the primary menu and main selection area.  You will always
    return to this area when moving from one function to another.
    As you glance over this main menu two features will catch your
    attention.  First, there is the main sliding menu select on the
    left side of the screen.  Second, there is an information box
    in the lower left side of the screen.


   Data Recovery Reference   Page  9



    The information box in the lower left will not contain information
    until something is done in the program.  This box will remind you
    of what is currently selected as well as MARK setting in effect.

    The outlined box on the lower right never changes and simply
    informs you how to slide up and down the main selection menu
    as well as make selections.


   Data Recovery Reference   Page 10

    QUICK START (for experienced computer users)


    Start DRS

    Once you are at the main menu, select INITIALIZE floppy
    or Hard Drive.

    Next select BROWSE/SAVE/PRINT for which ever type you
    selected (floppy or HD).

    From the VIEW screen you can MARK then SAVE or PRINT the
    information your looking for on the bad disk.

    NOTE:  Be sure to use the BROWSE only for the type drive
           selected.  If you initialized with a floppy then
           only use the floppy browse.


   Data Recovery Reference   Page 11


    If you have a disk that has gone bad or been damaged
    and you only need a safe combination or a simple piece
    of information it might be just as easy to locate the
    information then hit your print key there by dumping
    your screen to the printer.

    DRS does not force you to memorize anything.  Everything
    is displayed right in front of you and is readily useable.


   Data Recovery Reference   Page 12


    FLOPPY DRIVE HELP (F1)


    To select the FLOPPY DRIVE HELP screen use the UP or DOWN arrow
    key to highlight FLOPPY DRIVE HELP.  Next select the highlighted
    choice by hitting ENTER.  As the user becomes more familiar with
    the menu options it will become easier to just hit the appropriate
    F or FUNCTION key.  The function key for FLOPPY help is F1.

    After selecting FLOPPY HELP you will be presented with the first
    of four screens with information pertaining to the operation of
    floppy recovery.  To exit the first screen hit Q to QUIT or hit
    any other key to call up the next FLOPPY HELP screen.  The procedure
    is the same for each successive screen.

    Floppy Help Screen 1

     The first help screen explains that before you can attempt
     to recover a bad floppy disk you must initialize the DRS
     software.  DRS requires this function to correctly read a
     bad floppy disk.

    Floppy Help Screen 2

     Screen 2 goes on to explain how initializing is accomplished
     by inserting a good formatted floppy disk of the type and
     size of the bad disk you want to read.  Next DRS reads and
     establishes the parameters for the drive to be used (more on
     this under F2).

    Floppy Help Screen 3

     Help level 3 explains some of the unusual things that can
     occur during DRS operation.  DRS will always try to read a
     drive even if there is nothing in it.  The odd part is that
     it will do it just fine and return what it finds, ZEROs!
     When DRS reads beyond the end of a disk it does not return
     an error message but keeps displaying the same last sector.

    Floppy Help Screen 4

     Screen 4 now explains that after initializing the drive to
     remove the good, formatted floppy and replace it with the
     bad disk.  After selecting F3 or highlighting the BROWSE
     option you are now ready to browse through the bad disk
     marking, saving, viewing or printing the areas you are
     interested in.

                      NOTE

      You may Q for QUIT on any help screen and
      return to the main menu at any time.


   Data Recovery Reference    Page 13


    FLOPPY DRIVE INITIALIZE (F2)


    The first window that pops up instructs you to insert a good formatted
    disk.  This is not the help area that tells you what is going to happen
    but actually the time to insert the good disk.

    The second window wants to know which drive you are using?  The one you
    just put the disk in!  Enter A, B, C or D.  It makes no difference if
    the letters are upper or lower case.  After you hit a letter key
    this window will be replaced by window number three which will display
    the status of the drive being read.

    After the initialize segment is complete you should remove the floppy
    disk and insert the damaged disk.  You are ready to proceed to the
    BROWSE, SAVE, PRINT section.


   Data Recovery Reference   Page 14


    BROWSE/SAVE/PRINT (F3)


    After selecting F3 or highlighting the F3 choice you will be
    presented with the BROWSE/SAVE/PRINT screen.  This is the main
    screen of the DRS software.

    From here you are presented with a view screen and 12 selection
    keys as shown below.


   ╔════════╗ ╔════════╗ ╔═══════════╗ ╔════════╗ ╔═════════╗ ╔════════╗
   ║ (A)uto ║ ║ (B)EEP ║ ║ (D)ISPLAY ║ ║ (F)IND ║ ║ (P)RINT ║ ║ (S)AVE ║
   ╚════════╝ ╚════════╝ ╚═══════════╝ ╚════════╝ ╚═════════╝ ╚════════╝
   ╔════════╗ ╔════════╗ ╔═══════════╗ ╔════════╗ ╔═════════╗ ╔════════╗
   ║ ()UP  ║ ║ ()DWN ║ ║  (J)UMP   ║ ║ (M)ARK ║ ║ (H)ELP  ║ ║ (Q)UIT ║
   ╚════════╝ ╚════════╝ ╚═══════════╝ ╚════════╝ ╚═════════╝ ╚════════╝

    The letter enclosed in each bracket is the key to be depressed to
    activate that function.


       Example:  If you wanted to QUIT you would hit the Q key
                 which would highlight the (Q)UIT box momentarily
                 as well as beep followed by a return to the
                 previous level.


    The upper right box on the screen will display the current sector
    that is being viewed.  The area between the current sector display
    and the boxed keys is the text or hex display area.  This area will
    display the current selected sector.


   Data Recovery Reference   Page 15


    BROWSE/SAVE/PRINT (F3) - THE (A)UTO KEY



    The A or AUTO key causes DRS to BROWSE your disk by incrementing the
    sector count by plus one and then displaying the sector.  The process
    continues to repeat itself until you press any key.  The BROWSE begins
    at whatever sector you were at when you first selected AUTO.

         EXAMPLE:  You might want to begin a BROWSE at
                   sector 100 and you are currently at
                   sector 675.  You might J for JUMP to
                   sector 100 then A for AUTO to watch
                   DRS page through the disk sector by
                   sector.

    The AUTO browse mode will bring up several new features.  You will
    be presented with a speed control feature.  This is handled by the
    () and () keys.  The up arrow makes the display move faster and
    the down arrow slows the display down.  There is a display index
    number provided on the right hand edge of this line.

    While you are in AUTO mode the words, "SPACE BAR = STOP" will appear
    at the bottom center of the screen, directly above the key box
    display.  When you touch any key the AUTO mode stops and then
    redisplays the last sector you were viewing.  You can now easily
    arrow UP or DOWN to find the exact sector you are looking for.


   Data Recovery Reference   Page 16


    BROWSE/SAVE/PRINT (F3) - THE (B)EEP KEY



    The B or (B)EEP key is the simplest key on the menu.  When you
    press it the first time it shuts off the BEEP sound heard with
    each key hit.  If you press it a second time then it turns the
    sound back on.  When you hit the (B)EEP key a message is
    automatically displayed showing the current status of the beep
    sound.  This message will erase itself from the screen after
    3-seconds.

   Data Recovery Reference   Page 17


    BROWSE/SAVE/PRINT (F3) - THE (D)ISPLAY KEY

    The (D)ISPLAY key switches between ASCII (Normal Characters) and
    HEX displays.  When you hit the D key you are toggled to the
    opposite display that is currently being displayed.  After D is
    pressed the BROWSE display will refresh showing the current sector
    in the new format, ASCII or HEX.


   Data Recovery Reference   Page 18


    BROWSE/SAVE/PRINT (F3) - THE (F)IND KEY


    The (F)IND feature is designed to locate text for you.  After you
    hit the F key you will be asked where to begin the search.  You
    should enter the sector number where the search is to begin.  Next
    you will be prompted for the search text.  Enter up to ten characters
    that DRS is to search for.  DRS is case sensitive at this point so
    be sure to only use capitals where they belong.  DRS will now begin
    to search for the text specified and at the location specified.  The
    search will progress one sector each step until the data is found.

    FIND is the slowest running operation in DRS, therefor you should
    position the FIND start as close to the area to be searched.  This
    assumes that you know where you would like to begin.  If the start
    area is unknown the FIND will have to start at sector zero (0).

    After DRS finds the text being searched for it will stop the search
    and display the found text sector.


   Data Recovery Reference   Page 19


    BROWSE/SAVE/PRINT (F3) - THE (P)RINT KEY


    To utilize the print function you must first have something MARKED.
    See (M)ARK instructions.  When you hit P for PRINT DRS will begin
    to print out each sector starting with the lowest marked sector and
    proceeding up to and including the largest marked sector.  You will
    be asked if you want to print ALL characters or just non-control
    characters.  If you select ALL sometimes your printer will do
    unpredictable things based on the control characters, carriage
    returns and line feeds it finds in the data stream.  If you select
    straight ASCII the control characters will be suppressed and your
    remaining ASCII data will be printed.


   Data Recovery Reference   Page 20


    BROWSE/SAVE/PRINT (F3) - THE (S)AVE KEY


    The (S)AVE key saves data between MARK sets into a file that you
    name.  (See MARK command for details on MARK.)  When you are
    prompted for a file name you may use any valid DOS name.  This
    means up to 8 valid characters followed by a period and then 3
    more valid characters.

       INVALID Characters are:

           .  "  /  \  [  ]  :  |  <  >  +  =  ;  ,
           and all characters below ASCII 33.

    Included with the file name may be a path.  If you do not want
    the data saved into a file on the current logged path just add
    the drive and path name to the front of the file.

       EXAMPLE:  To save MDATA.TXT to drive C and in the subdirectory
                 \TEMP you would type C:\TEMP\MYDATA.TXT

    If you pick a name that already exists DRS will inform you that
    the name selected already exists and then prompt you for a new
    name.  Once the name you used is correct then each sector between
    the data you marked is saved into your named file.

    After the data has been saved DRS will inform you that ALL MARKS
    have been cleared and you are ready for the next function.


   Data Recovery Reference   Page 21


    BROWSE/SAVE/PRINT (F3) - THE ()UP KEY


    The   arrow key causes DRS to increment one sector and then display
    that sector.  This is the key to use for browsing or moving short
    distances in the browse area.  As you hit the up arrow key not only
    will the display change but the sector counter will also increment
    by one in the upper right corner of your screen.

    If you are on the very last sector of the disk the display will not
    change.  The sector display will change but the data in the view
    window will not.


   Data Recovery Reference   Page 22


    BROWSE/SAVE/PRINT (F3) - THE ()DOWN KEY


    The   arrow key causes DRS to decrement one sector and then display
    that sector.  This is the key to use for browsing or moving short
    distances in the browse area.  As you hit the down arrow key not only
    will the display change but the sector counter will also decrement
    by one in the upper right corner of your screen.

    If you are on the very first sector of the disk the display will not
    change.  It will remain on the zero sector along with the sector
    counter.

    BROWSE/SAVE/PRINT (F3) - THE (J)UMP KEY

    The (J)UMP key is used to move large numbers of sectors.
    If you are on sector 10 and wanted to move to 1500 it would
    be prohibitive to use the up arrow key.  It is simpler to JUMP
    to 1500.  When you select JUMP you will be prompted for the
    sector number via a small window.  After the JUMP is complete
    the sector JUMPED to is displayed.


   Data Recovery Reference   Page 24


    BROWSE/SAVE/PRINT (F3) - THE (M)ARK KEY


    The (M)ARK key is used to block a section of space to allow
    separate manipulation of that area.  It has been designed
    to be very simple to use.  Hit the MARK key when you are in the
    sector you want to begin in.  A pop-up window will tell you
    that the first MARK has been set.  Next, JUMP or arrow up to
    another sector.  Hit the MARK key again.  Once again a small
    pop-up window will inform you that a second mark has been set.
    Each of the pop-up windows will clear themselves in a few
    seconds.

    Now that a block has been marked you may SAVE the block to
    a file or PRINT the block.  The third alternative is to hit
    the MARK key a third time which will cause DRS to inform
    you that all MARKS have been erased.  At the time of this
    writing, the second mark must be higher in sector number
    than the first mark.


   Data Recovery Reference   Page 25


    BROWSE/SAVE/PRINT (F3) - THE (H)ELP KEY


    The (H)ELP key provides brief information on using MARK, SAVE and
    PRINT.  If you hit the help while on the view screen a window pops
    onto the screen with information concerning MARK.  Hitting any
    other key at this time will present the next screen with SAVE
    information and so on.  There are a total of four help screens
    in this area.  You may quit viewing HELP screens at any point by
    simply hitting Q for QUIT.


   Data Recovery Reference   Page 26


    BROWSE/SAVE/PRINT (F3) - THE (Q)UIT KEY


    The (Q)UIT key is simply what it says.  When you hit the Q key you
    will leave the BROWSE/SAVE/PRINT area and be returned to the main
    sliding menu area.  All marks you set as well as the current logged
    drive and the current active sector are still in effect.  This way
    you will be able to return to the same place you were at.


   Data Recovery Reference   Page 27


    FLOPPY INFORMATION (F4)


       The floppy drive information selection presents you
       with valuable information concerning disk sizes, types,
       sectors, tracks and where different types of information
       are stored on a disk.

       Each floppy type, 2.8M, 1.44M, 1.2M, 720K, 360K and 1.8K
       are presented in detail.

       Where is the data, FAT area, format information, etc on a
       disk?  All of these things are covered in this area.


   Data Recovery Reference   Page 28


    HARD DRIVE HELP (F5)


    To select the HARD DRIVE HELP screen use the UP or DOWN arrow
    key to highlight HARD DRIVE HELP.  Next select the highlighted
    choice by hitting ENTER.  As the user becomes more familiar with
    the menu options it will become easier to just hit the appropriate
    F or FUNCTION key.  The function key for HD help is F5.

    After selecting HD HELP you will be presented with the first
    of six screens with information pertaining to the operation of
    hard drive recovery.  To exit the first screen hit Q to QUIT or hit
    any other key to call up the next HD HELP screen.  The procedure
    is the same for each successive screen.


    Hard Drive Help Screen 1

     The first help screen explains that before you can attempt
     to recover a bad disk (floppy or hard) you must initialize
     the DRS software.  DRS requires this function to correctly
     read a bad disk.


    Hard Drive Help Screen 2

     Screen 2 goes on to explain how initializing is accomplished
     by use of the F6 key for hard drives.


    Hard Drive Help Screen 3

     Help level 3 explains that manual setup made be used by
     selecting F8.


    Hard Drive Help Screen 4

     Screen 4 now explains that any time you change from floppy
     to hard or hard to floppy you must reinitialize the system.


    Hard Drive Help Screen 5

     Screen 5 directs your attention to the hard drive list
     contained in the F8 function.  This list contains numerous
     hard drive manufactures as will as models, heads, cylinders
     and capacities.


    Hard Drive Help Screen 6

     Screen 6 simply directs your attention to the printed manual
     for additional help.


                    NOTE

      You may Q for QUIT on any help screen and
      return to the main menu at any time.


   Data Recovery Reference   Page 29


    HARD DRIVE SETUP (F6)


    The first screen to appear after selecting F6 is a notice
    explaining the differences in floppy recovery vs. hard
    recovery.  There is a statement concerning the value of
    hd recovery as well.

    The next screen to pop-up will ask which hard drive you want
    to work on.  Your choices are C, D, E, F, Etc.

    As soon as you hit a letter you will be presented with the
    last screen which shows information and status of the drive
    you picked.  Another key hit will take you back to the
    primary sliding menu.  You may exit at any time and from any
    screen by hitting the Q for QUIT key.

    You are now ready to BROWSE, SAVE or PRINT from the BAD hard
    drive.


   Data Recovery Reference   Page 30


    HARD DRIVE BROWSE/SAVE/PRINT (F7)

    *This area is actually a repeat of the FLOPPY view area.  If
     you are comfortable with the floppy area you can skip this
     area.

    After selecting F7 or highlighting the F7 choice you will be
    presented with the BROWSE/SAVE/PRINT screen.  This is the main
    screen of the DRS software.

    From here you are presented with a view screen and 12 selection
    keys as shown below.


   ╔════════╗ ╔════════╗ ╔═══════════╗ ╔════════╗ ╔═════════╗ ╔════════╗
   ║ (A)uto ║ ║ (B)EEP ║ ║ (D)ISPLAY ║ ║ (F)IND ║ ║ (P)RINT ║ ║ (S)AVE ║
   ╚════════╝ ╚════════╝ ╚═══════════╝ ╚════════╝ ╚═════════╝ ╚════════╝
   ╔════════╗ ╔════════╗ ╔═══════════╗ ╔════════╗ ╔═════════╗ ╔════════╗
   ║ ()UP  ║ ║ ()DWN ║ ║  (J)UMP   ║ ║ (M)ARK ║ ║ (H)ELP  ║ ║ (Q)UIT ║
   ╚════════╝ ╚════════╝ ╚═══════════╝ ╚════════╝ ╚═════════╝ ╚════════╝

    The letter enclosed in each bracket is the key to be depressed to
    activate that function.


       Example:  If you wanted to QUIT you would hit the Q key
                 which would highlight the (Q)UIT box momentarily
                 as well as beep followed by a return to the
                 previous level.


    The upper right box on the screen will display the current sector
    that is being viewed.  The area between the current sector display
    and the boxed keys is the text or hex display area.  This area will
    display the current selected sector.


   Data Recovery Reference   Page 31


    BROWSE/SAVE/PRINT (F7) - THE (A)UTO KEY


    The A or AUTO key causes DRS to BROWSE your disk by incrementing the
    sector count by plus one and then displaying the sector.  The process
    continues to repeat itself until you press any key.  The BROWSE begins
    at whatever sector you were at when you first selected AUTO.

         EXAMPLE:  You might want to begin a BROWSE at
                   sector 100 and you are currently at
                   sector 675.  You might J for JUMP to
                   sector 100 then A for AUTO to watch
                   DRS page through the disk sector by
                   sector.

    The AUTO browse mode will bring up several new features.  You will
    be presented with a speed control feature.  This is handled by the
    () and () keys.  The up arrow makes the display move faster and
    the down arrow slows the display down.  There is a display index
    number provided on the right hand edge of this line.

    While you are in AUTO mode the words, "SPACE BAR = STOP" will appear
    at the bottom center of the screen, directly above the key box
    display.  When you touch any key the AUTO mode stops and then
    redisplays the last sector you were viewing.  You can now easily
    arrow UP or DOWN to find the exact sector you are looking for.


   Data Recovery Reference   Page 32


    BROWSE/SAVE/PRINT (F7) - THE (B)EEP KEY


    The B or (B)EEP key is the simplest key on the menu.  When you
    press it the first time it shuts off the BEEP sound heard with
    each key hit.  If you press it a second time then it turns the
    sound back on.  When you hit the (B)EEP key a message is
    automatically displayed showing the current status of the beep
    sound.  This message will erase itself from the screen after
    3-seconds.


   Data Recovery Reference   Page 33


    BROWSE/SAVE/PRINT (F7) - THE (D)ISPLAY KEY

    The (D)ISPLAY key switches between ASCII (Normal Characters) and
    HEX displays.  When you hit the D key you are toggled to the
    opposite display that is currently being displayed.  After D is
    pressed the BROWSE display will refresh showing the current sector
    in the new format, ASCII or HEX.


   Data Recovery Reference   Page 34


    BROWSE/SAVE/PRINT (F7) - THE (F)IND KEY


    The (F)IND feature is designed to locate text for you.  After you
    hit the F key you will be asked where to begin the search.  You
    should enter the sector number where the search is to begin.  Next
    you will be prompted for the search text.  Enter up to ten characters
    that DRS is to search for.  DRS is case sensitive at this point so
    be sure to only use capitals where they belong.  DRS will now begin
    to search for the text specified and at the location specified.  The
    search will progress one sector each step until the data is found.

    FIND is the slowest running operation in DRS, therefor you should
    position the FIND start as close to the area to be searched.  This
    assumes that you know where you would like to begin.  If the start
    area is unknown the FIND will have to start at sector zero (0).

    After DRS finds the text being searched for it will stop the search
    and display the found text sector.


   Data Recovery Reference   Page 35


    BROWSE/SAVE/PRINT (F7) - THE (P)RINT KEY


    To utilize the print function you must first have something MARKED.
    See (M)ARK instructions.  When you hit P for PRINT DRS will begin
    to print out each sector starting with the lowest marked sector and
    proceeding up to and including the largest marked sector.  You will
    be asked if you want to print ALL characters or just non-control
    characters.  If you select ALL sometimes your printer will do
    unpredictable things based on the control characters, carriage
    returns and line feeds it finds in the data stream.  If you select
    straight ASCII the control characters will be suppressed and your
    remaining ASCII data will be printed.


   Data Recovery Reference   Page 36


    BROWSE/SAVE/PRINT (F7) - THE (S)AVE KEY


    The (S)AVE key saves data between MARK sets into a file that you
    name.  (See MARK command for details on MARK.)  When you are
    prompted for a file name you may use any valid DOS name.  This
    means up to 8 valid characters followed by a period and then 3
    more valid characters.

       INVALID Characters are:

           .  "  /  \  [  ]  :  |  <  >  +  =  ;  ,
           and all characters below ASCII 33.

    Included with the file name may be a path.  If you do not want
    the data saved into a file on the current logged path just add
    the drive and path name to the front of the file.

       EXAMPLE:  To save MDATA.TXT to drive C and in the subdirectory
                 \TEMP you would type C:\TEMP\MYDATA.TXT

    If you pick a name that already exists DRS will inform you that
    the name selected already exists and then prompt you for a new
    name.  Once the name you used is correct then each sector between
    the data you marked is saved into your named file.

    After the data has been saved DRS will inform you that ALL MARKS
    have been cleared and you are ready for the next function.


   Data Recovery Reference   Page 37


    BROWSE/SAVE/PRINT (F7) - THE ()UP KEY


    The   arrow key causes DRS to increment one sector and then display
    that sector.  This is the key to use for browsing or moving short
    distances in the browse area.  As you hit the up arrow key not only
    will the display change but the sector counter will also increment
    by one in the upper right corner of your screen.

    If you are on the very last sector of the disk the display will not
    change.  The sector display will change but the data in the view
    window will not.


   Data Recovery Reference   Page 38


    BROWSE/SAVE/PRINT (F7) - THE ()DOWN KEY


    The   arrow key causes DRS to decrement one sector and then display
    that sector.  This is the key to use for browsing or moving short
    distances in the browse area.  As you hit the down arrow key not only
    will the display change but the sector counter will also decrement
    by one in the upper right corner of your screen.

    If you are on the very first sector of the disk the display will not
    change.  It will remain on the zero sector along with the sector
    counter.


   Data Recovery Reference   Page 39


    BROWSE/SAVE/PRINT (F7) - THE (J)UMP KEY


    The (J)UMP key is used to move large numbers of sectors.
    If you are on sector 10 and wanted to move to 1500 it would
    be prohibitive to use the up arrow key.  It is simpler to JUMP
    to 1500.  When you select JUMP you will be prompted for the
    sector number via a small window.  After the JUMP is complete
    the sector JUMPed to is displayed.


   Data Recovery Reference   Page 40


    BROWSE/SAVE/PRINT (F7) - THE (M)ARK KEY


    The (M)ARK key is used to block a section of space to allow
    separate manipulation of that area.  It has been designed
    to be very simple to use.  Hit the MARK key when you are in the
    sector you want to begin in.  A pop-up window will tell you
    that the first MARK has been set.  Next, JUMP or arrow up to
    another sector.  Hit the MARK key again.  Once again a small
    pop-up window will inform you that a second mark has been set.
    Each of the pop-up windows will clear themselves in a few
    seconds.

    Now that a block has been marked you may SAVE the block to
    a file or PRINT the block.  The third alternative is to hit
    the MARK key a third time which will cause DRS to inform
    you that all MARKS have been erased.  At the time of this
    writing, the second mark must be higher in sector number
    than the first mark.


   Data Recovery Reference   Page 41


    BROWSE/SAVE/PRINT (F7) - THE (H)ELP KEY


    The (H)ELP key provides brief information on using MARK, SAVE and
    PRINT.  If you hit the help while on the view screen a window pops
    onto the screen with information concerning MARK.  Hitting any
    other key at this time will present the next screen with SAVE
    information and so on.  There are a total of four help screens
    in this area.  You may quit viewing HELP screens at any point by
    simply hitting Q for QUIT.


   Data Recovery Reference   Page 42


    BROWSE/SAVE/PRINT (F7) - THE (Q)UIT KEY


    The (Q)UIT key is simply what it says.  When you hit the Q key you
    will leave the BROWSE/SAVE/PRINT area and be returned to the main
    sliding menu area.  All marks you set as well as the current logged
    drive and the current active sector are still in effect.  This way
    you will be able to return to the same place you were at.


   Data Recovery Reference   Page 43


    HARD DRIVE INFORMATION (F8)


    The hard drive information section provides information pertaining
    to sector sizes, capacities and useful information regarding hard
    drive recovery.  While designing DRS I realized that there are many
    persons who will not know how many sectors and heads they have as
    well as other pertinent information.  For this reason if you make
    any errors while setting up DRS it will default to AUTOMATIC setup
    and try to read your drive, regardless.

    The hard drive information area will give you a brief idea as to
    where some of the information on your hard drive may be found.
    this information appears as follows:

    BOOT AREA - Contains the information necessary to begin loading
                DOS into memory.  Area also contains information
                regarding number of tracks, sectors, etc.  Start at
                sector (0).

    FILE ALLOCATION AREA - This area hold your file information as
                well as attributes, time, date, starting sector and
                file size.  This area starts at sector (17) on many
                drives.

    ROOT AREA - This area is created when the hard drive is formatted
                and is limited as to how many files can be listed
                here.  This area holds, file name, attributes,
                sectors, etc.

    FILE AREA - The file area follows behind all other areas.  The
                file you are looking for may be broken up in several
                segments and scattered through out the disk.  This is
                the largest area of your disk.

   Data Recovery Reference   Page 44


    DOCUMENTATION (F9)


    DRS has two forms of documentation.  One is the printed manual
    and the other is the same manual under the F9 function.  Many
    people seem to like having the manual in the program for easy
    reference while just as many like a complete book in front of
    them.

    If you are using the book under the main sliding menu F9 function
    then simply PgUp or PgDn to the area you are looking for.  You may
    also use the up and down arrows to move one line at a time. "Q"
    for QUIT at any time will return the user to the main sliding
    menu.


   Data Recovery Reference   Page 45


    EXIT PROGRAM (F10)


    F10 simply terminates the DRS program refreshes and clears the
    computer screen leaving you at the default DOS prompt.
