That was it.  This is an old mac pro that I put centos on yesterday.  It
had 4 disks in it and this is the 3rd that has died.  A faculty member had
it for 5-6 years and it was on 24/7.  It's been in the junk pile for
several months.  I guess long enough for the disks to go south from sitting
on so long then going off for a period...  maybe....  Anyone heard of this?
