Hard Disk Won't Spin on UNIX PC

[John P. Rouillard]

This is additional information to the article:

  AT&T Unix-PC Hard Disk error **HELP** References: <880 at umb.umb.edu>

dd at umb.umb.edu had a disk with a bad bearing.  He swapped the driver
boards on the disks.  His disk with the bad bearing worked. i.e. the
driver boards were ok.  Next he tackled the disk itself.  He tried to
spin the shaft clockwise by hand.  The shaft was jammed.  Then he
tried spinning it counter-clockwise. This freed it and it seems to be
working fine now.  

I would still like to know what caused the problem in the first place
and I would like to get instruction on the care and feeding of the
hard disk to prevent this from happening in the future.
