Hi, Got a HDD that stopped working. I'd like to get some data off it, but want to try and do it myself (it's that tinkering thing). It spins up. I do NOT hear the normal scratchy noise like when the heads crash. Tried putting it in the fridge for 30 min. and then running it (had a couple people say this might work). No luck. Tried tapping it on all sides. No luck. So, I bought another drive exactly like it. First I tried swapping the electronic board from the good HDD to the bad HDD. No luck. So, I started to get desperate. I too apart the drives and took the head units out and swapped them. No luck. At this point I have swapped EVERYTHING from the good drive to the bad drive except the platters and motor that makes them spin and still have had no luck. The PC just doesn't see the HDD there at all. I can put a good HDD in there and it works fine (so it's not the PC itself). I moved everything back to the good HDD and it still works. I know the whole deal about "clean room environment", but hey it still works for now. Anyway, does anyone have a clue what to try? Since I swapped everything, I can't figure out what's wrong. Is there something you have to do to make the new head unit recognize a new set of platters?
