Summary: How to identify Bad lot of ST11200N's.
Keywords: SCSI Seagate Disks ST11200N FAQ?

From what I hear (not a regular reader), this is somewhat of a FAQ,
although it isn't actually in the FAQ's.

I have in front of me three Seagate ST11200N's.

Drive 1 shows cylinders.. Most likely an actual head crash.

Drives 2 and 3 test fine, but give random write errors when actually
used (putting one in to a news server as /var/spool/news will give
errors in 5 mins or less, and lead to a panic in a few hours).

Drives 2 and three have lots of similar numbers on them, so they may be
part of that "bad batch" of seagates.  Does anyone know how to identify
those bad drives?  Here's some of the #'s on the front label:

		Drive 1		Drive 2		Drive 3
--------------------------------------------------------------------------
Part #		947001-043	947001-026 	947001-026
Serial #	TS746402	WS002900	WS020158
Lot #		S-02-9415-4	O-01-9310-6	O-01-9322-2
CSC Lot #	7770429		7770358		7770358

I'd really like to determine if these errors are caused by the drives,
or the machine, because at this rate, it seems like out sparc is eating
drives, and I don't want to keep feeding it forever!

Any help would be appreciated.  Email preferred: stevek@cooper.edu
