I had things going OK, unpacking the source tarballs, when suddenly the
disk accesses nearly stopped. The indicator light would come on and I'd
hear a couple of head movements, then the light would go off and nothing
happened for ten seconds or so, and repeat ad infinitum.
After I hit the reset button and it went to fsck the drive, it would go
merrily along for a while, then exhibit the same behavior.
I wondered if it might be some kind of disk geometry problem, though the
drive initially formatted properly. So I booted the install floppy, mounted
up the hard disk, and was able to copy the snapshot tarballs and most of the
source tarballs onto my other system (saving the necessity of downloading
them again). When it got part way through the xsrc tarball, the drive
started acting up again, so now I'm convinced it's a bad sector problem.
My question is: What can I do to handle the problem? (Please keep in mind
that I'm a newbie concerning PC options, experienced admin otherwise.)
Here's the specifics:
Gateway 486DX/33
Seagate ST32122A IDE

Contrary to popular belief, Unix is user friendly.
It just happens to be selective about who it makes friends with.
