AFAICT, after watching the Seagate and HDD Guru forums for over a
year, Seagate's 7200.11 and 7200.12 series (and related Maxtor
families) appear to be plagued with head problems.

BTW, SMART is reporting 0 seek errors.

One other thing I notice is that the Head Flying Hours (1383) is
greater than the Power On Time Count (1060).

FWIW, there is a CC3D firmware update for your model.

Well, if you are right, then Hitachi managed to get chinese Q/A under
control, while Seagate did not...

Aehm, that would be 8706938 seek errors and counting.
Raw value is in third from end position, this is a cur&paste
from HDD Sentinel and I was too lazy to edit it.

Hmm. That is indeed strange. Did not notice it myself.

Could be worth a try. Not sure I have the nerve though,
and I will pick up a WD replacement tomorrow.

The lower 32 bits of the raw SER value count the number of seeks. The
upper 16 bits count the seek errors. So SMART is reporting 0 errors in
8706938 seeks.

Hmm. Right. Seagate did handle that attribute differently. Thanks
for reminding me. I keep forgetting.

So basically what I have is the command timeouts. They are real and
what made me look at the disk in the first place. I also have
seen the occasional pending sector that vanished a short time later
(seconds).

That would indicate it is something like read errors and recovery
from that takes too long. With the hints that current Seagates may
have head problems, this one will definitely be turned into a
paperweight.
