History of Disk eXPress:
1.01 11/25/91 First release of DSKEXP (Disk Express). Package
includes this history file, the documentation file,
DSKEXP.EXE (DOS version of the program) and
DSKEXP2.EXE (OS/2 version of the program).
1.02 12/04/91 Bug fix for version 1.01.
DSKEXP:
- Failed to read diskette correctly if a new
diskette is insert in drive. If the diskette
has been previously accessed by DOS, DSKEXP
will read the diskette correctly.
- Failed to read 160K/180K diskettes.
- Diskette conversion failed for 160K/180K
diskettes.
DSKEXP and DSKEXP2:
- Incorrect diskette fragmentation report for
1.2M diskette.
- Diskette conversion is now limited to different
form factor diskettes (5.25" to 5.25" conversion
and 3.5" to 3.5" conversion are not allowed).
- Corrections to documentation.
1.04 02/19/92 DSKEXP:
- /f not working in version 1.02 is fixed.
DSKEXP and DSKEXP2:
- New logic for FAT scanning. Previous versions
may not correctly determine the actual last
sector used unless /a is specified.
- New Ctrl-C and Ctrl-Break routines.
- Incomplete output file will be deleted when user
hits Ctrl-C/Ctrl-Break.
New major release:
2.00 05/19/92 Name changed to DXP.EXE. Added Xtract as a standlone
diskette image extractor. DXP and XTRACT are now
dual mode applications (OS/2 and DOS). Refer to
DXP.DOC for all the new features for Version 2
release.
Bugs fixed in 1.04 are carried over to version 2.
The known ones under 1.04 are:
- Ran out of near heap under OS/2 if a CMD.EXE
replacement shell is used.
- FAT scanning logic may miss sparsely allocated
clusters and the bad clusters count may be off
by one.
- /c conversion switch under OS/2 is now working.
2.01 09/04/92 Minor image description display code bug fix.
Reworked all display routines so that all errors
and warning messages are sent to stderr. Normal
messages are sent to stdout.
Corrections to spelling errors in documentation.
2.02 10/17/92 Improved error messages and error logic.
(internal release)
Better detection of invalid image header by DXP.
Improved documentation.
2.03 10/23/92 Improved error handling when reading an unformatted
diskette when running the program under OS/2.
