- DISCLAIMER
- ==========
-
- WRTDSK is careware: anyone who uses it is obliged (by one's conscience) to
- help the local Red-Cross organization. And, of course, it is distributed as
- it is, with no warranty. In no event shall author, or his family and pets,
- be liable for any incidental, indirect, special or consequential damages made
- by use of this software. Anyway, don't get frightened. It is not much worse
- than the similar utilities.
-
-
- DESCRIPTION
- ===========
-
- WRTDSK is an utility primarily written for copying image files on floppies.
- It is intended to be used with formatted DOS floppies with capacity of 360,
- 720, 1200 or 1440 K. Data read from the file is written onto 'raw device'.
-
- It is very important to use floppies without any bad sectors. You can
- determine this by unconditional formatting with MS-DOS FORMAT (use /U switch)
- and then running CHKDSK. If you have DOS version 6.20 or newer, you can use
- SCANDISK utility to examine floppies that are allready formatted. To prevent
- possibility of writing on bad sectors WRTDSK has the ability to verify the
- data written.
-
- The length of an image file has to be multiple of 512 bytes (DOS sector
- size). If it is not, WRTDSK writes all the data, but last sector data is
- overwritten entirely. This has an effect only if more files are specified to
- be written on the same floppy.
-
- If anything goes wrong, WRTDSK can be stopped by pressing Ctrl-Break.
-
-
- USAGE and PARAMETERS
- ====================
-
- Display of short help that is available with WRTDSK /? follows:
-
-
- Writes DOS files to raw floppy device.
-
- WRTDSK [drive:] {file [file...] | @filelist} [/F:size] [/V:level] [/A:attempts]
-
- drive Floppy drive (default A:)
- file DOS file name (wildcards allowed)
- filelist File containing list of files to copy
- size Floppy disk capacity in Kbytes (default CMOS data)
- level Verify level: 0 = none, 1 = CRC, 2 = Read + CRC (default 1)
- attempts Number of write attempts after failure (default 4)
-
-
- drive:
- ------
-
- Floppy drive letter, if specified, has to be the first parameter. If it is
- not the default is drive A:.
-
- filenames (or @filelist)
- ------------------------
-
- Specifies file(s) to be written on floppy disk(s). Source files may not
- reside on disk that is specified as the destination. There are two ways to
- specify files: one is to count all the filenames on the command line and the
- other is to enter these filenames in separate list file and specify list file
- (preceded by sign '@'). Examples are:
-
- > WRTDSK source.* bin.*
- > WRTDSK b: one.dsk two.dsk three.dsk
- > WRTDSK a: @dir.lst
-
- Wildcards are allowed: first example above will copy all files beggining
- with "source." and then all files beginning with "bin.". Note that if there
- is a file named "source", it will not be copied. Files will be sorted in
- the alphabetical order before being written to disks.
-
- If that order of disks isn't suitable, the use of list file can greatly
- simplify the copying. Supposing that one wants to copy all the files starting
- with "disk", he (she) could write:
-
- > DIR /B /O disk*.* > dir.lst
-
- edit "dir.lst", sort files manually and than use the third example shown
- above. File names in list file must not contain wildcards.
-
- /F:size
- -------
-
- Specifies floppy capacity in Kbytes. Optional, but recommended. If you use
- floppy with capacity smaller than the drive (360K floppy in 1200K drive)
- the use of this parameter will suppress probing for disk formatting. If disk
- formatting cannot be recognized, the user has to restart WRTDSK and then use
- /F switch.
-
- File size and disk capacity do not have to match. More small images can be
- written on one or more large floppies and also spanned from one to another.
- The choice to span or not is entered at the prompt. Also, large image files
- can be stretched onto several floppies.
-
- /V:level
- --------
-
- Optional parameter, specifies the verification level. The possibilites are
- V:0, means no verification; V:1, verification via BIOS call that verifies data
- written by its checksum; and V:2 verification by reading data just written,
- comparing it with original and after that doing BIOS checksum verification.
- Verification level 2 greatly reduces speed, while level 1 does it much less.
- Default level is 1.
-
- /A:attempts
- -----------
-
- Number of attempts to write data on floppy before an error is reported.
- This parameter is optional, the default is 4.

- CREDITS
- =======
-
- The author wishes to thank Croatian Red Cross (RedCross@hck.hr) for
- understanding him being late to the job after long nights of programming,
- Igor Bujanovic (igor@srce.hr) for inspiration of WRTDSK, Kees J. Bot
- (kjb@cs.vu.nl) for his help and support in developing this utility and
- finally everyone who uses it and helps Red-Cross.

-
- BUG REPORTS and COMPATIBILITY LIST
- ==================================
-
- Any documented bug reports sent by e-mail will be appreciated. Machine
- type, including BIOS, bus, FDD controller, drive and floppy types should
- be noted. Also, feedback about successful use will be welcome to create a
- compatibility list. Please note the WRTDSK version too.
