Hi,

I've had a strange problem for a while, with Windows resetting
occasionally without warning. Most of the time it works fine. I ran
chkdsk /4, and got stuck at 11% of stage 4. It does the same if I boot
from my spare hard drive, so I guess it can't be a software problem.
The seagate diagnostic tools (run from a boot CD) hang as soon as they
start the quick or the full disc check.

Seems fairly clear there's a hardware problem. Before I get a
replacement drive... is there a way to check that it is the drive at
fault and not the controller/motherboard? Some more sophisticated
diagnostic software, perhaps?

(Ideally I'd test the drive in another PC, but I don't really have
access to one.)

The drive is a SATA Barracuda 7200.8 and the motherboard Asus A8V.

thank you for your time!
