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. Data Recovery Reference Page 5 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. Data Recovery Reference Page 6 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. Data Recovery Reference Page 23 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.

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.
