We are having trouble with a hard disk we bought for one of
our pc's a little while ago.

It seems that every so once in a while, (more often than to
be just annoying) we have a great deal of reading the hard disk.
Running a Norton disk test will sometimes turn up four or
five bad clusters, but will very seldom show the same bad sectors
(or any bad clusters at all) when run a second time.

The clusters are usually the lower numbered ones  (<500).

The disk is a Seagate ST225 and and OMTI 5510 controller.  We
bought them from Jade electronics a couple of months back.

Because of the randonmness of the errors, one of the hardware
types around thought that it might have something to do with
seek/settle times.

Does this sound reasonable?  Is there any patch available to
DOS to modify the seek/settle times?  Has anyone had any other
bad/good/indifferent experiences with Seagate Drives, OMTI
controllers or JADE elex?

				Thanks very much in advance:
