Subject: Multivolume tar gives errors

This may have been covered in the past, but I didn't see it in the FAQ.
And this might be a duplicate post as well, since our news system here is a
bit deficient. But anyway, here goes:

I was trying to back up some rather large files I had pulled off of tsx11.
Not having done a multivolume tar before, I decided to give it a shot.
Nothing else going on with the machine (no compiles in other VCs, or
anything else for that matter).

So, I do the invocation, and it begins to chug away merrily on the HD.
Stops it's thing on the HD, then starts writing to /dev/fd1 - which in my
case is a 3 1/2" high density floppy. Cool, everything's going fine.

Then, the hard drive kicks back in while the floppy is being written to.
Nasty noises from the floppy, a rash of 'Floppy Reset Called' messages, and
an I/O error or two.

Bad. Tried a few other times, some different files (smaller subset), let
it run through, restored to a different directory, and diff -b'd them.
Sure enough - different.

Had something similar happen here at work on a Toshiba 5200, but I just
chalked it up to a bad floppy. Now I'm wondering...

System specs:

386/33
AMI BIOS
4M RAM
4M swap
ST296N with ST01 controller
/dev/fd0 is 1.2M floppy
/dev/fd1 is 1.44M floppy

MCC .96 interim distribution everything

Could this be a SCSI issue? I'd be surprised, since I saw it on the laptop
here, which I'm pretty sure has an IDE.

Any thoughts on the matter, or pointers of where to look for answers would
be appreciated. As it stands now, I don't think I can do a backup of the
disk, so I hope I don't screw something up there.... Ahh, the funness of
it all...;^)
