fuji 2333 problems

[Tim Garlick -- UCSC Computer Center]

Folks,

We have a Fujitsu 2333 disk on a 3/160 which appears to be dying, but I'd
like a second opinion.  This disk has only got 4 months on it since it was
obtained from Sun (it's "factory reconditioned").  Here's what the system
looks like, followed by the errors.  (Note that the errors are not all on
the same partition nor on the same track or head.)  The disk errors are
causing frequent crashes.  Is there anything we can do to this disk to
make it better?  Would reformatting fix it?  This is the third 2333 that
has crapped out on us on this system in two years.

Thanks for any help/advice.
