I can confirm this, I have a Seagate Momentus 5400.3 sata disk, and it

I had before this disk an IBM/Hitachi one, and it doesn't have this
behaviour.
Take a look at this bug report:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/67810
There are some references and some patches against 2.6.20 kernel. This
bug is confirmed there.
Yup. Last I heard, Tejun has fixed this, and queued the code
for 2.6.22 via James B. But this could be considered a rather
nasty regression in 2.6.21, in that it does seem to cause
significant and unnecessary wear and tear on the drive mechanisms.
I'll patch it locally on my own machines, but what about the tens
of thousands of other Seagate notebook drive owners out there?

Compaq Presario V2000 series, with a new Seagate ST9120821A
120GB 5400RPM drive.

That makes no noise at all except normal drive seek noises.

Hmm.
Power_Cycle_Count ... 108
Power-Off_Retract_Count ... 90
I did a normal poweroff and the retract count went to 91.
There is an almost-unnoticeable click when I do it that way.
