- TAPEDISK.EXE The device driver. Win95 Long File Name Aware
-
- TAPEDISK.EXE allows you to install the TAPEDISK device driver from
- either config.sys or autoexec.bat. TAPEDISK.EXE will consume about
- 6K of conventional memory and may be loaded into high conventional
- emory (i.e. above the 640K mark).
-
- For example: If are using a Quarterdeck's QEMM you can loadhigh the
- TAPEDISK.EXE driver. It will consume about 45K of upper memory and
- .2K (about 200 bytes) of memory below the 640K mark.
-
- The syntax of the TAPEDISK.EXE device driver line is:
-
- DEVICE=C:\TD650250\TAPEDISK.EXE /ID=N [optional switches]
-
- TAPEDISK.EXE has a number of optional switches and required switch.
- The only required parameter is /ID=N.
-
- /ASKINSTALL=DONT|YES|NO prompts at boot time if you wish to
- install the TAPEDISK driver.
- Yes|No changes the deferral response.
-
- /BOOTCAPTURE=N number of times that TAPEDISK will
- "trap" CNTL/ALT/DEL's. Default=2
-
- /COMMENT=YES|NO specifies if you want comment prompt
-
- /COMPRESSION=YES|NO activate data compression switch on
- data compression capable drives
-
- /DOORKEEPUNLOCKED keeps the door to the tape drive
- unlocked when a tape is active.
- Default is Door locked
-
- /FLOPPY=YES|NO causes DOS to see the tape drive as
- a non-removable device
-
- /HA=N Host Adapter number
-
- /ID=N is a required switch. The SCSI ID
- associated with the tape drive
-
- /K=K kilobytes reserved in EMS memory for
- directory entries. Minimum required is
- 60 bytes per file name in DOS and Win3.1x
- or 180 bytes per file name in Win95.
- Default=500
-
- /N=N number of clusters in EMS memory cache.
- Default=10
-
- /ORDER=ALL|FAST sets default for TDDSKCPY /ORDER=
-
- /QUIET sets default used by TDFORMAT, TDLOAD,
- TDDSKCPY, TDUNLOAD. Reduces messages to
- the screen. Default=NOT quiet.
-
- /RESERVEDRIVELETTER allocates a non-functional drive letter
- when you respond "NO" to the /ASKINSTALL=
-
- /SEEKTIMEOUT=T sets default /SEEKTIMEOUT for TDLOAD
- command. Default = drive dependent
-
- /TAPESIZE=M sets tape capacity default in megabytes for
- TDFORMAT if tape size not determined.
- Default = drive dependent
-
- /TDMIN=M megabytes before the physical end of the
- tape "end of paper" condition where
- TAPEDISK will flush all cached buffers.
- Default=30
-
- /TIMEOUT=T [number of seconds from the time a host
- adapter issues a command to the tape drive
- before reporting a "not responding error."
- Default = drive dependent
-
- /UNINSTALL removes previous installed TAPEDISK driver
- that was installed at the command line
-
- *******************
- TDGETMEM & TDRETMEM
- *******************
-
- TDGETMEM serves one main purpose: to reserve EMS memory for those
- components of TAPEDISK that need it. When you use TDLOAD (either
- inside of outside of Windows), TDLOAD will determine if a TDGETMEM
- was run prior to TDLOAD for the drive letter assigned to the TAPEDISK.
- If TDLOAD determines that TDGETMEM reserved EMS memory, then TDLOAD
- will not allocate any more EMS memory and will use the EMS memory
- allocated by TDGETMEM.
-
- The syntax of the TDGETMEM command is:
-
- TDGETMEM T: [optional switches]
-
- where T: is the TAPEDISK drive letter assigned by DOS during the boot
- process.
-
- TDGETMEM has one required and two optional switches.
-
- /EMS=K is a required switch: is the number of bytes, in
- Kilobytes of EMS memory, you wish to have TDGETMEM
- reserve for TAPEDISK's exclusive use. Minimum required
- is 60 bytes per file for DOS and Win3.1x + 1400 KB. The
- amount of memory that you specify in the /EMS=K parameter
- will be rounded up to the nearest 16K. Win95 uses Long
- File Names please allow for 120-180 bytes per file.
-
- /STATUS reports how much EMS was allocated assuming
-
- /WIN95RESERVE=K is used to temporary skip over memory used by Win95 that was
- illegaly obtained by Win95.
-
- TDRETMEM releases EMS memory reserved by TDGETMEM.
-
- The syntax of the TDRETMEM command is:
-
- TDRETMEM T:
-
- ***************
- The Basic Three
- ***************
-
- There are three basic commands you need to use to use the SCSI tape drive
- as a logical device: TDFORMAT, TDLOAD, and TDUNLOAD.
-
- *******
- TDFORMAT
- ********
-
- TDFORMAT initializes a tape so that TAPEDISK recognizes it. Formatting a
- TAPEDISK is somewhat like a low level and high level format of a hard disk.
-
- The syntax of the TDFORMAT command is:
-
- TDFORMAT T: [optional switches]
-
- Other than for /COMPRESSION=YES|NO we recommend that you do not use the
- other option switches.
-
- TDFORMAT has a number of optional parameters.
-
- /ASK=YES|NO {If you specify "NO" uses all the default responses
- during formatting a tape. If not used, Default=YES}
-
- /COMPRESSION=YES|NO data compression used. The default value is
- NO (so that data can be shared among DAT/DDS
- users) and is only effective for those tape
- drives that support hardware compression.
- Use of compression can significantly improver
- performance.
-
- /FORCE=YES|NO will unconditionally low lowlvel format the tape
-
- /QUIET will reduce the amount of messages sent to the
- screen
-
- /SLOT=N is the slot number (media ID) for autoloaders.
- If you don't have an autoloader (e.g. HP1553A),
- don't use this option
-
- /TIMEOUT=T same as TAPEDISK.EXE
-
- ******
- TDLOAD
- ******
-
- TDLOAD is similar to UNIX's "mount" command. It connects your tape to
- DOS allowing DOS to access your tape as if it were a disk.
-
- If you attempt to access a TAPEDISK before you have TDLOADed it, you will
- get the same kind of "Drive Not Ready" message that you get from DOS if
- you have not inserted a floppy into a floppy drive. Unlike a floppy drive,
- a "retry" won't work: you must TDLOAD the TAPEDISK first. Just "Abort"
- the operation, TDLOAD the tape, then retry the operation.
-
- If you have not run TDGETMEM before TDLOADing, TDLOAD will allocate EMS
- memory from the EMS memory pool. If you ran TDGETMEM before TDLOADing,
- TDLOAD will get its memory as allocated by TDGETMEM.
-
- TDGETMEM is required to be used if you intend to issue TDLOAD while
- Windows is running.
-
- The syntax of the TDLOAD command is:
-
- TDLOAD T: [optional switches]
-
- TDLOAD has a number of optional switches.
-
- /BACKGROUND is not available when /SLOT= is specified
- Does not load the tape, rather it positions
- the tape to the TDLOAD position (at EOD). This
- positioning will be performed off-line on
- systems where the ASPI manager, host adapter
- and tape drive support disconnect and multiple
- SRBs. On some slow QIC drives the positioning
- to TDLOAD point can take several minutes and for
- these drives you will want to use this switch.
-
- /CHAPTER=N N is the Chapter number that you wish to load
- other than the last TDUNLOADed chapter. Chapter?,
- What is a chapter? A chapter is a data set that
- is presented to you as a DOS disk. Once a chapter
- is closed (using TDUNLOAD) the data referenced by
- the chapter cannot be altered. A new chapter can
- be constructed that includes a reference to this
- chapter. The new references can be altered but the
- data and the old references cannot. If you wish to
- reference older data (or data from a different
- collection) you would use the /chapter=n switch to
- specify the chapter number.
-
- TAPEDISK creates a chapter when you use the TDDSKCPY command.
- A chapter is also created every time you TDLOAD, modify the data
- on the tape, and then TDUNLOAD. It is TDUNLOAD that creates the
- new chapter. If a tape is TDLOADed and not modified another new
- chapter is not created. In effect you are creating a "snapshot"
- of the TAPEDISK at the time of the TDUNLOAD.
-
- TAPEDISK automatically loads the last closed chapter when TDLOAD is
- issued. You can access previous chapters by using the /CHAPTER=
- parameter. Example:
-
- TDLOAD D: /CHAPTER=1
-
-
- /CLEARCHAPTER If specified then a new "empty" Chapter will
- be created. The geometry of the empty Chapter
- will be that which was specified when the tape
- was formatted. Use /CLEARCHAPTER in place of
- deleting all directories and files
-
- /FORCE=YES|NO has two purposes. First is to speed up the
- loading of previously loaded TAPEDISKs. The second
- is an enhancement of the ability to recover data
- from a corrupted TAPEDISK
-
- /K=K kilobytes reserved in EMS memory for directory
- entries.
-
- /N=N is the number of clusters that you want to cache
- in EMS memory. The larger the number the faster
- that TAPEDISK will operate. The default value is 10.
- The minimum allowable value is 1 and the maximum
- allowable value is 32.
-
- /QUIET will reduce the amount of messages sent to the
- screen.
-
- /SEEKTIMEOUT=T As tapes get longer and longer, the amount of
- time that it takes to seek from one end of the tape
- to the other gets longer. M represents the number
- of seconds between the time a seek is initiated and
- the time TAPEDISK expects the seek to complete at
- some time in the future, this value may need to be
- increased.
-
- /SLOT=N specifies a tape slot number on the Autoloader.
-
- /TDMIN=T same as TAPEDISK.EXE
-
- ********
- TDUNLOAD
- ********
-
- TDUNLOAD flushes all buffers and performs other "bookkeeping" tasks and
- returns the memory to the EMS free pool (unless the EMS memory was
- obtained by way of TDGETMEM).
-
- TDUNLOAD also serves a secondary function. There are some tape drives
- that will not unlock the tape after a system reboot; that is, you push the
- button to eject the tape from the drive and the tape won't come out. To
- eject the tape you can use TDUNLOAD. There are no special parameters.
-
- DO NOT ever power the tape drive off in an attempt to eject the tape! You
- may corrupt the tape!
-
- The syntax of the TDUNLOAD command is:
-
- TDUNLOAD T: [optional switches]
-
- Where D: is the TAPEDISK drive letter assigned by DOS during the boot
- process.
-
- TDUNLOAD has a number of optional parameters.
-
- "A Chapter comment" This is an optional, quoted string which
- "identifies" a chapter. You insert an intelligent
- comment to identify the Chapter either on the
- command line using this quoted text option or
- through the COMMENT= YES option below. This option
- is NOT preceded by a "/".
-
- /CLEARCHAPTER is only relevant if /RELOAD is also used. If you
- specify /RELOAD and also /CLEARCHAPTER then a new
- "empty" Chapter will be created.
-
- /COMMENT=YES|NO Indicates if you will or will not be prompted for
- a Chapter comment. This option is overridden by
- quoted text specified on the TDUNLOAD command line.
-
- /FORCE=YES|NO TAPEDISK will not normally create a new Chapter
- upon TDUNLOAD. There are times when you will
- wish that a new Chapter be written even though the
- current Chapter was not modified.
-
- /QUIET reduces the amount of messages sent to the screen.
-
- /RELOAD Equivalent to, but faster than a TDUNLOAD followed
- by a TDLOAD. This causes the Chapter data to be
- written thus insuring data integrity up until that
- point. The TAPEDISK remains logically connected to
- MS-DOS.
-
- /TIMEOUT=T same as TAPEDISK.EXE
-
- *****************
- Utilities for DOS
-
- TAPEDISK has several utilities design to optimize the use of tape.
-
- ********
- TDDSKCPY Win95 Long File Name Aware
- ********
-
- TDDSKCPY is not available with this Demo version. This version will only
- store 250 megabytes to a tape. The following description illustrates the
- power TAPEDISK offers for backing up your hard disks.
-
- TDDSKCPY is similar to DOS's DISKCOPY in that it copies an entire (hard)
- disk to your TAPEDISK. TDDSKCPY only works on "local" drives, that is,
- drives that are directly connected to your computer. Even though your CD-
- ROM drive may be directly connected to your computer, DOS thinks of it as a
- "foreign" drive that is accessed via the "network redirector." Thus, you
- cannot use TDDSKCPY to copy a CD-ROM. To copy files from your CD-
- ROM use any file oriented access such as TDXCOPY, COPY, Windows File
- Manager, XTREE, etc.
-
- Example use of TDDSKCPY:
-
- TDDSKCPY C: "Comment for C:" D: "Comment for D:" T:
-
- Would copy drives C: and D: to the TAPEDISK on drive T:, and will place
- drive c: into Chapter 1 and drive d: into Chapter 2.
-
- Note, drive T: is the drive letter for the TAPEDISK. In this example
- (system with 2 hard disk) the drive letter for TAPEDISK would most likely
- be drive E:. Please substitute the proper drive letters for your system
- when trying to reproduce our examples.
-
- *******
- TDXCOPY NOT Win95 Long File Name Aware
- *******
-
- TDXCOPY performs most all of the same functions of XCOPY and is
- optimized for use with TAPEDISK. It currently does not support LFN.
- Use Windows 95 Explorer to move/copy files.
-
- The syntax of the TDXCOPY command is:
-
- TDXCOPY source [\filter] target [optional switches]
-
- /BUSYWAITTIME=T is how long to wait if a file is found to be
- busy before going to the next file.
-
- /D:aa/bb/cc copies files modified on or after a specified date.
-
- /DOS Send progress messages to standard DOS facilities.
-
- /EMPTY creates empty directories.
-
- /HIDDEN copies files marked with DOS's "hidden" flag.
-
- /MAXERRORS=n is the number of errors permitted before processing
- stops.
-
- /MODIFIED copies files with the archive bit "set".
-
- /NOWAITMSG forces processing not to wait for user input when
- damaged files are found.
-
- /QUIET supresses activity messages.
-
- /SYSTEM copies files marked with DOS's "system" flag.
-
- /TIME reports processing time.
-
- where:
- source is a pathname indicating the source directory.
- \filter is an optional file filter, uses the same file
- filters as DOS.
- target is a pathname indicating the target directory.
-
- *******
- TDXCOMP NOT Win95 Long File Name Aware
- *******
-
- TDXCOMP is a useful utility that is also independent of TAPEDISK. It can be
- used to compare any two directory trees to see if there are any files that
- are different in the trees.
-
- The syntax of TDXCOMP is:
-
- TDXCOMP source [\filter] target [optional switches]
-
- Switches:
-
- /BUSYWAITTIME=T
- /DOS
- /HIDDEN
- /MODIFIED
- /QUIET
- /SHOWTIME
- /SYSTEM
- /TIME
-
- ******
- TDXDIR NOT Win95 Long File Name Aware
- ******
-
- TDXDIR will tell you the size and number of files in a directory and all its
- subdirectories. It can also list the starting cluster number as well as
- TAPEDISK block number if the directory being listed is on a TAPEDISK.
-
- The syntax of the TDXDIR command is:
-
- TDXDIR path[\filter] [optional switches]
-
- /BUSYWAITTIME=T
-
- /DATETIME displays the date and time the file was last modified.
-
- /FILESIZE displays the files size in bytes.
-
- /HIDDEN displays "hidden" files.
-
- /MODIFIED displays files with archive bit set.
-
- /STARTCLUSTER displays the starting cluster of the file,
- assuming the file is not on the network or CD-ROM.
-
- /SUBSIZE displays the accumulated number of bytes of files in
- all directories and sub-directories.
-
- /SYSTEM displays "system" files.
-
- /TAPEBLOCK displays the starting block on the TAPEDISK
- where the file is found.
-
- /VERBOSE displays all available information of the above
- switches.
-
- Note, the default switch is /SUBSIZE. Therefor TDXDIR with no switches
- produces just a totals line.
-
- ******
- TDXDEL NOT Win95 Long File Name Aware
- ******
-
- TDXDEL allows you to delete all files in a directory and all its
- subdirectories.
-
- TDXDEL deletes either:
-
- 1) All files and all subdirectories of a particular directory
- 2) All files matching a file filter in all subdirectories of a
- particular directory.
-
- The syntax of TDXDEL is:
-
- TDXDEL directory [\filter] [optional switches]
-
- /DELALL Deletes all files and directories regardless of the
- state of the system, hidden or read-only flag. Does
- not override network privileges.
-
- /HIDDENALSO deletes all "hidden" files.
-
- /NOWARN suppresses the "OK to delete" warning".
-
- /READONLYALSO deletes "read-only" files.
-
- /SYSTEMALSO deletes "system" files.
-
- /TIME
-
- /VERBOSE
-
- directory is a pathname indicating the directory (and all
- sub-directories!) you wish to delete.
-
- ********
- TDUPDATE NOT Win95 Long File Name Aware
- ********
-
- TDUPDATE performs whatever actions are necessary to make one directory
- (the source) have identical files and directories as another (the target).
- TDUPDATE uses file size, file time and date stamp, and the file's file
- attributes (e.g. "archive" attribute) to determine if files and directories
- need to be deleted and/or added. One significant difference between
- TDUPDATE and TDXCOPY is that TDUPDATE does not have a "file filter"
- specification for the source directory. It currently does not support LFN.
- Use Windows 95 Explorer to move/copy files with Long File Names.
-
- The syntax of TDUPDATE is:
-
- TDUPDATE source target [optional switches]
-
- /EXCLUDE=filter is a file exclusion filter
- /X=filter is a file exclusion filter (short form of switch)
- /BUSYWAITTIME=T is the time to wait for files to become unbusy.
- /DOS sets activity display to DOS mode
- /MAXERRORS=N number of errors before TDUPDATE quits.
- /NOWAITMSG supresses "Waiting for..." message
- /NOWARN don't warn me
- /PRESERVEARCHIVE Preserves the archive flag when the source file is
- updated to the target. If not used both source and
- target archive is cleared.
- /TIME display the amount of time consumed by TDUPDATE
- /TRIALRUN counts and displays files that would be deleted or
- copied.
- /VERBOSE displays copious messages.
-
- *****
- TDSET
- *****
-
- TDSET allows you to set two TAPEDISK system parameters:
-
- 1) tape logical write protection on-and-off.
- 2) the ioctl return value.
-
- The syntax of the TDSET is:
-
- TDSET T: [optional switches]
-
- /WRITEPROTECT=NOCHANGE|ON|OFF changes logical write protection.
- /IOCTLRETURN=N specifies the IOCTL return value.
-
- ******
- TDWAIT
- ******
-
- TDWAIT allows you to wait for a certain time, a certain date and time, or a
- certain number of hours, minutes, and/or seconds before TDWAIT will
- relinquish control to the next command in a batch file. For Desqview and
- Windows, TDWAIT will relinquish the time slice. TDWAIT can be used to wait
- for a certain time before TDXCOPY, TDDSKCPY, etc. begins operation. This
- can be very useful for unattended back up of a network.
-
- The syntax of the TDWAIT command is:
-
- TDWAIT T: argument
-
- ARGUMENT is a DAY, TIME, or DATE value. DAY and TIME, or DATE and TIME
- may be used together. When TIME is used with an A or P, HH is in
- a 12 hour mode; therefore, the value of HH is limited to 1 through
- 12. A is AM, and P is PM.
-
- HH:MM:SS HOURS:MINUTES:SECONDS
- HH:MM:SS[A|P] AM|PM
- MM-DD-YY MONTH:DAY:YEAR
- DAY:HH:MM:SS DAY=SUN, MON, TUE, WED, THU, FRI, SAT
-
- An explanation of the TDWAIT arguments can be viewed by issuing a
- TDWAIT with no parameters on the command line. TAPEDISK displays the
- following output.
-
- ******
- TDCHAP
- ******
-
- TDCHAP lists the information about Chapters on your TAPEDISK.
- The syntax of the TDCHAP command is:
-
- TDLOAD T: [optional switch]
-
- /NCHAPTERS=N is the chapter number for which you want information.
-
- ******
- TDSEEK
- ******
-
- TDSEEK allows you to initiate a seek to a file and then go off and do other
- things while the tape spins to the file that you want.
-
- The syntax of the TDSEEK command is:
-
- TDSEEK T:[filename][optional switches]
-
- filename name of the file to position the tape to.
- /EOD space to end of known data.
- /Wait until seek is completed.
-
-
- ***
- VFB
- ***
- VFB is Windows 95 version of and enhancement of the TDUPDATE utility. It is
- designed to be Windows 95 long file name aware and provides a means of
- synchronizing your backups. When used as intended you can attain extrordinary
- compression ratios and data rates. Compression ratios of 25:1 and data rates
- of 500MB/minute are an ordinary expectation. This utility takes advantage of
- the TAPEDISK chaptering facility to attain these figures. This capability is
- a great time saver and dramaticaly reduces media consumption.
