Not exactly. It's a Cheetah 4.3 GB : Vendor: SEAGATE Model: ST34501W Rev: 0018

The drive is only 2 weeks old. And there would be a couple of damaged sectors, because it happens while reading at different locations.

I just had a system lockup with a new message on the console:
Kernel panic aic7xxx: (aic7xxx-queue) Couldn't find a free SCB.
That line came 3 times. Should I try different compile time options for the aic7xxx driver?
