2.02 1992-01-27
- Fixed a problem with /ENV switch. It had a loose pointer that could
mess up with some parameters or cause a null pointer assignment message.
- Installed code for registration reminder and registration keys. The
reminder is not big, but I guess registered users do not want to see it.
2.01 1992-01-08
- Option /AVAILABLE:n added to resize the disk to the size when it has
n Kbytes space available.
- Option /MINSIZE added to resize the disk to the smallest size
possible or disable it if there is no data on it. This is the same as
/AVAILABLE:0
- Option /FILESPACE:n added to resize the disk to the size when it has
n Kbytes space for files.
- Added some ERRORLEVEL returns. SRDISK.EXE should now returns nonzero
ERRORLEVEL, if there were problems with the format (errors, failure,
would destroy contents, but not allowed to).
- Aborted formatting could enable the disk although no memory was
allocated for it. Error handling fixed.
- Setting environment variables did not work with DOS prior to version
3.30. Changed environment variable setting so that it does not try to
find the command processor, but just modifies the parent's environment.
Also it is better made sure that the parent is real.
- Device drivers did not detect read/write errors. Now it is detected
that MS-Windows Enhanced mode does not emulate EMS 4.0 correctly and
causes errors.
- Disabled possibility to allocate disk while in MS-Windows Enhanced
mode. Windows frees the memory allocated by the program when the DOS
window is closed, so the disk memory would be lost then.
- A number of other bugs removed and features cleaned.
2.00 1992-12-12
- Memory allocation bug that gave XMS error A7 removed.
- Disk resizing could change the reported size of clusters at some rare
cases although the cluster size was not changed.
- Now asks if disk contents are to be removed if all the old data can
not fit the new disk being created.
2.00 BETA 3 1992-11-06 A pre-release version for the version 2.0
- Made two versions of the device drivers: full featured and small.
- Full featured device drivers now have their own stack so that user
need not care of it. Small device drivers do not have this.
- Optimized some code for faster operation.
- Fixed a problem with root directory sectors being cleared with resize.
- DR-DOS problems solved. The device driver did not preserve flags and
this seemed to have caused the trouble with DR-DOS.
- Now should correctly estimate the available memory size before trying
to format. Still possible to fail with XMS though - this is due to the
incomplete services of XMS.
- Memory allocation while preserving disk contents fixed.
2.00 BETA 2 A pre-release version for the version 2.0
- Memory allocation while preserving disk contents fixed.
- Changed the multiplex number back to what it was in 1.x versions. BETA
1 had a different number so that it will not conflict with existing 1.x
version disk.
- Boot sector is now updated correctly when disk is resized. Thus you
can diskcopy a disk into RAM disk, resize it and diskcopy it to a disk
of another format - great for boot disks too!
2.00 BETA 1 A pre-release version for the version 2.0
- SRDISK now tries to preserve the disk contents by default.
- Device driver SRDEMS.SYS for EMS memory support. Requires EMS version
4.0.
- Device drivers are now compatible with DOS DISKCOPY command. Use
SRDISK /F switch to configure SRDISK to the same format as the floppy
and you can then diskcopy between the floppy and RAM Disk. Great for
disk duplication - no need to swap the disks any more. Also DISKCOPY
to/from the floppy is much faster than copying each file one by one.
- Alternative command line options and some new options. The longer
options can be shortened if they remain unambiguous.
- /U (or /UNCONDITIONAL or /ERASE) switch can be used to clear the disk.
- /F (or /DOSFORMAT) has many FDFORMAT disk sizes and formats added. The
available sizes are listed in SRDISK.DOC.
- New options are added to better support different floppy formats:
/MEDIA:n - Defines the media ID byte
/HEADS:n or /SIDES:n - Defines sides on the disk
/SECTORS:n or /SPT:n - Defines sectors per track
/DEVICETYPE:n - Device type (0=360K floppy, 1=1.2M floppy,
2=720K floppy, 3=8-inch single density,
4=8-inch double density, 5=hard disk,
7=1.44M floppy, 9=2.99M floppy)
- Error condition handling for batch operation enhanced.
/ASK - Ask about destroying data (default)
/YES or /FORCE - Destroy data if necessary to complete
/NO - Do not destroy data
1.42
- Restricted FAT copies to maximum of 2. DOS 5 did not manage well if
there were more.
- SRDISK.SYS caused the block devices loaded after is to have bad drive
letters assigned to them.
- Tried to read root directory when there was no disk.
- MS-DOS 5 does not interpret the disk size correctly after it has had
to face a bad disk. Deviced a get-around for the bug.
- Memory allocation has been fixed to help the memory managers.
- Made stack larger.
1.41 1992-06-06
- I started to take a licensing fee from corporate users. Sorry, I have
no other income currently. I tried to make the prices reasonable, but if
you feel the prices are too high for your casual use, you can try to
bargain.
- One '!' had disappeared from the env.c causing the /E not to work.
Hopefully not many copies of the 1.40 version got out.
1.40 1992-06-03
- DR-DOS 6 hangup solved by passing a valid looking BIOS Parameter Block
at init.
- Added a check for DR-DOS 5, since SRDISK did not seem to work with it
unless sector size was 128 bytes. Under DR-DOS 5 sector size now
forced to 128 bytes.
- resolve_drive() now finds drive letters even if driver loaded high
with some upper memory manager utility. Also if driver not found,
disks should be configurable anyway as 1:, 2:, etc. - although better
would be to tell the drive letter in CONFIG.SYS.
- Disk size 1 with /F:1 to get rid of drive not ready reports.
- Unless forced sector/cluster/root dir sizes, adjust them properly.
- Have srdisk handle allocation of known types of memory. Also enhanced
allocation to hopefully work better with DesqView.
- Reorganized source to several files. Also many other minor changes and
source beautifying.
- Multiplex interrupt interface changed a bit.
- Borland C++ 3.0 produced bad code handling long integers and thus the
beginning of FAT was a little wrong. Changed the code to one not
having a bug.
1.30 1992-01-18
- Changed to freeware from public domain
- Changed the driver control from IOCTL calls to multiplex interrupt.
- Added support for over 32M RAM drives (up to 4096M). Over 32M drives
need DOS 4+ because they use over 0xFFFF sectors.
- Added /V switch for program verbosity control. /Y now only forces the
disk format, it does not make the program less verbose.
- Support for chained drivers. These drivers all contribute memory for
the same virtual drive. Added switch /M to control how much memory may
be used by each driver in the chain.
- Formatting reads the root directory to find out if there is anything
that would be destroyed. If not, it will not ask for permission to
destroy.
- Added /E switch to set environment variables SRDISKn to show srdisk
drives.
- Scans Drive Parameter Table on DOS 2 and 3 to find the drive letters,
if necessary.
1.20 1991-10-04
- Fixed name of program by adding the missing 'Re' to 'Sizeable'.
- Added 16 bit FAT support; more 'sizeable' disks that had over 4077
clusters were not operational. Due to DOS's inconsistent behaviour,
disks with over 4077 and under 4088 clusters (or over 65518, possible
with 128 byte clusters and 8M disk size) are avoided by making
clusters bigger.
- Added DOS lookalike disk formats via switch /F.
- The FAT number is now defined via switch /A instead of /F.
- The time of format is stored in volume label.
- Upgraded to IOCTL_msg version 1.20 which tells the type of memory used
by the driver.
- Disallow sectors greater than 512 bytes as DOS can not handle them
properly but rather crashes when it encounters them.
- Allow clusters up to 8 kilobytes.
- Enhanced help.
1.10 1991-09-06
- Added full support for multiple FATs. 1.00 had the /F switch, but no
support for it in formatter.
- Updated to IOCTL_msg versio 1.10 so that media byte is no longer used
to indicate the media change but to indicate the drive is RAM disk.
- Some minor fixes.
1.00 1991-06-09 Initial release
