Hello
First option - how much free space is there on the HD? If there's a
lot, then use archive prog to create big compressed file on HD, then
use SPLIT or suchlike to break up archive into 95Mb bits to put onto
ZIP drive, and reconstitute archive later.
Otherwise, I'd guess ARJ your best bet. Version I have does not have
-hm! option, so I don't know what that is. -r option is OK. In my
info, -v option should be -v95000000, i don't know about -v95M variant.
Otherwise there's a -va option which auto detects space available on
destination drive. From what you say, ARJ is not interpreting the -v95M
parameter correctly and is defaulting to 1.4Mb floppy instead.
Remove garbage from email addr to reply.

Hello
Further to earlier message....
Just spent about an hour of my life watching ARJ do it's bit.
I ran my C: to ZIP disk using the -va option.
C: had 4228 files comprising 63.7 Mb
Result, an .arj file on ZIP disk of 30.5 Mb, process completed fine,
although disk swap process not required. I suggest you try that and
see what happens.
Hopefully, you'll do yourself a floppy boot disk etc so you've got
DOS, Guest etc and ARJ (etc) so you can restore.

Thank's for your help although I ended up using the included DOS
5 backup program suggested earlier.

10-20MB HDD space left so this isn't really an option.

I was using ARJ V 2.85 for which these commands are listed in
the documentation. -hm! indicating for it to use XMS memory, and
the M modifier doing as it indicates. However I tried not using
XMS, typing 95000000, using -va and many other combinations all
with the same result.
By the way, in my newsreader your messages are appearing as new
posts rather than relpies.

I tried ARJ again and was amazed to find that it worked as it
should, however when I tried running it of the boot disk I had
used before, it went back to stopping as it had before. As the
commands I used in both cases were the same, I think the boot
floppy must be the problem, however how this could be I don't
know.

current directory. Check if the floppy is write protected. Even if not, if
ARJ is creating a file on the floppy, it may be stopping because there is
not enough free space.

I think the problem was in how I had the memory set up,

however I think I'll stop playing around with ARJ because
after the last try it (or the zip driver or...) somehow
corrupted one of my main directories. Now I'll have to go
through all this again.
Hints on any way to recover the directory? I've only tried
TestDisk.

Hallo Computer Nerd Kev,

The reason you haven't got much useful advice for this is that you
haven't given enough information to go on. How was "one of your main
directories" corrupted? Were the file names scrambled? Were the files
not found when you tried to open them?
You probably have a vesrion of CHKDSK.ERXE on your MS-DOS 5 (?)
machine. That should be the first step. Use it to repair your disk.

Try using data recovery in your search terms. If the FS/directory structure

was damaged, hopefully your backup is a byte for byte disk image and not
just a compressed file of whatever files were readable.
