The tape drive is on a different machine (SCSI), using rdump.
I'm sorry, I didn't save the screen before rebooting to 2.2.14.
The errors were occuring on /var/spool/mail which is a 10.9 GB partition
on the EIDE drive (last partition on the drive). All of the other partitions
are relatively small (2GB or less) and they all backed up OK, but it would
consistantly error out on /var/spool/mail. Badblocks would not find any bad
blocks, fsck wouldn't find any file system damage, and other than trying to
dump the file system, I didn't see any errors. But the errors went away under
2.2.14.
