I've recently tried to add Two new harddrives to my computer and niether of them work, when I attach them and turn on my computer it says stuff like, "Failure Imminent"?!?!?!? Going on that alone can you tell me the problem or do I need to get some pics.?
What kind of hard drives and were they used or new? You may want to look into some disk utility to scan the drive for errors... assuming the system is modern enough to support S.M.A.R.T.... of course I suspect that is telling you the drives are junk now. You might want to try the freeware, HDD Health.
