most people suggested that the disk may be going bad and to check the /var/adm/messages to see if there were any scsi messages, unfortunately
for me the messages file was woefully silent.

Kevin Sheehan suggested using raid, something that I would *like* to be
doing but don't have the opportunity for yet.

Jim Harmon suggested using the read only verify function of format to see
what was going on, something that I'll look at next time this happens.

The problem turned out to be several low numbered inodes had managed to
get themselves confused somehow. We ran fsck on the disk and got it to
lear everything up. some files needed to be restored from backup but
aside from (admittedly major) inconveinence to our users (none of the
students could log in at all) there was no trouble at all.

Thanks again to those who took the time to reply.

SAb.
