I get problems like that all the time when using PKZIP, I think it is a
bug in PKZIP.

What you have described sounds like a problem a friend of mine experienced
once. He bought a computer that had a very small scratch on the
motherboard. He switched disk drives, cables, I/O cards, and all of the
components worked fine in other systems, but not in his. The computer
apparently worked great, but the floppy drive simply refused to operate
properly. Try putting your diskette drive in the 486, my guess is that it
will probably work fine, and that you may need to replace your
motherboard.
