Quantum Lightning 540 AT Hard Disk

... Well it has drive to the spindle motor by the sounds of it. Whether the head assembly is intact is another matter. I think you can swap the boards on these things and expect them to still work - so using the combination of your chassis / motor / platter assembly and the logic board off a good drive might be enough - unless it is a fault in the head assembly. I have a Prodrive LPS 540AT in front of me right now which is likely the same thing as a Lightning. There seems to be just the one ribbon cable connecting the logic board to everything so a swap wouldn't be tricky and might cure things. Those drives used to be everywhere at one point so finding one shouldn't be too hard. Do double-check your drive cabling and BIOS settings (assuming it's a PC you're hooking up to) etc. - modern PC's seem to have a few billion settings for the disks and probably think you're using a new drive; they may make incorrect assumptions about data rates etc. I know Western Digital used to release diagnostic utilities for their drives and held them on their website; there may be similar Quantum ones floating around. cheers Jules ===== Backward conditioning: putting saliva in a dog's mouth in an attempt to make a bell ring. ________________________________________________________________________ Want to chat instantly with your online friends?
