Indeed, sorry. 600 PB... where did you get that drive? ;)

/M

What about those pre-fail messages on the other drive? are they something to worry about now?

Also, I ran the same thing on the 2 drives for md3 and got the same pre-fail messages for both of those, plus one had this nice little note:

==> WARNING: There are known problems with these drives,
AND THIS FIRMWARE VERSION IS AFFECTED,
see the following Seagate web pages:
http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207931
http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207951

4 seagate drives in this computer, this will make 3 failures since I put them in. I think the drives are still in warrenty. last time I replaced one it was good till something like 2012 or 2013. But any new drives will be WD.
