Thanks to all who replied.  I ran fsck on the disk yesterday and no
errors were reported; had already checked cables, etc.  About an hour
ago I rebooted the machine and let hal mount the attached drive as
opposed to mounting it manually, which I'd been doing via script.

Also, there was nothing unusual in the logs.

I changed my backup script to properly identify the new mount point
(/media/disk vs /media/bkup320G) and ran a test on a few home folders
which had errored earlier - interestingly, no errors now.

So, while my users are offline, I'm rerunning the  whole snapshot.  I
expect it will be fine, though I'm still not sure what got borked up.

When I convince the powers that be to get an internal drive for this
purpose so that we can do the rsync across the backplane vs USB 2.0,
I'll be doing the dance of joy :)

Again, thanks to all
