TOG
Thanks for the suggestion however I am not at EGDR at the moment. I might try that Linux suggestion if someone at work has a disk.
Alternatively, as I have 2 drives in RAID 0 would it be possible just to hook up the drives singly one by one as IDE to see if the PC "sees" them in case just one of them is duff? If one is recognised and then one is not (or vice versa) it would tell me that the unrecognised one is fried however I could save some money by reformatting the good one and reinstalling the OS?
Dont know what else to do now apart from trek to the local computer shop and give them money to fix it !!
