[arch-general] Problem with hard disk - not arch related

This is unrelated to arch, but I wanted to tell this to the list because maybe 
someone has a clue.

I have recently bought and installed a new sata hard disk. It has a couple of 
partitions, one with XFS which I use as storage.
It generally works fine, but sometimes something happens and it cease to work. 
I don't know if it's the disc's fault, because at the next restart the 
problems are gone. It seems that the controller sometimes gets lost. Dmesg 
says this:

So, what should I look for? Together with the disk, I installed an Nvidia 9800 
GT, which could also be the culprit, because maybe I haven't a proper power 
unit etc. - or not?

Thanks in advance to everybody!
