I have 2 Caviar SE 16, wd2500ks drives. Neither of these will work with my BIOSTAR G31-M7 TE motherboard. I am running Windows 7 Ultimate. The symptom is long pauses where the drive light is on solid for 30-60secs, and the machine pauses. After that it will begin responding again. This seems to happen on disk writes to new areas of the disk. It happens every couple of minutes. When I run the WD data lifeguard diagnostics on either drive I get a cable test failed.
However when I use a Seagate 320 gb, Barracuda 7200.10, drive the PC with windows 7 Ultimate works absolutely fine with no freezes/pauses whatsoever with the same motherboard and peripheral configuration.
I have made sure that the bios and all drivers are up to date on the motherboard. I cannot find any firmware updates for the WD drives. Is it possible the fact that the Caviar SE16 does not support Native Command Queuing could be a problem? Any one have any idea what is going on?
