Yes Sandra I am running Serial ATA raid with a striped array with 1 drive. Am thiniking of adding another one if it prooves to be stable.
I had another BSOD with the same meesage (kernel stack inpage error) shortly after posting that all was ok last night I also heard some clicking coming, i think from the HD so i think it must be on its way out.
Anyway I'm taking it back today (Again)!
Will let you know what happens
