I’ve also swapped platters to an identical working drive to salvage the data. But with that, swapping R/W heads even on a multi platter drive is a snap. I’ve made tools to seperate the heads from the platter, which you can also buy but they’re usually ridiculously expensive. Fiddling with the arm on a drive that’s not spinning can do more damage than good. You really need to determine wether or not that a stuck head is the issue first, though. So be not afraid of killing something which is already quite dead (-: With 3.5″ drives it was really simple, I’m just a normal guy with a not so clean admins office in that time. ![]() I can’t say anything about modern drives, but my point is it is absolute worth trying. I did not count them but I think there where about 10 and I got all needed data from them. In one case I had to replace the pcb of the drive, I just swapped with one of the same type. So even in case of a head crash the data loss was minimal and unimportant. If there was a head crash I copied with dd until it failed and than dd’ed the rest by skipping some cylinders. Next I closed it, powered up again and copied the data. Than I carefully rotated the disks, most times I recognized a blocking at first, than free movement. Once opened I looked for obvious things like arms in the wrong position or circular scratch marks (due to head crash). I powered up the patient and listened, if it did not spin up, I opened it. I never had anything near clean room conditions, just removes all unnecessary stuff from my desk cleaned it, and locked the door to avoid someone coming in and moving dust around. Professional data recovery was, due to the costs, always out of question. Most times the drives contained commercially important but not critical data. I did this also several times back in the 5 1/4″ and 3.5″ times. Posted in classic hacks Tagged data recovery, hard drive Post navigation Of course, if you brick the device, you can always scavenge it for parts. Be sure to avoid dust entering the drive, and take care not to touch the platters themselves. Truly valuable data should be left to the professionals, but if you’re skint or simply unbothered, it doesn’t hurt to have a go yourself. It’s important to note that this is a highly risky procedure, and not guaranteed to succeed. Amazingly, the repair is successful, and data is able to be recovered! ![]() With this done, the drive is reassembled and powered up. Using a screwdriver, the platters are rotated in their usual direction while gentle pressure is applied to pull the head away, being sure to use a light touch to avoid ripping the heads off entirely. opens the drive carefully, and notes that the head is indeed stuck to the platter, instead of sitting in its home position. When tapping the drive fails to unstick the heads, the next step is disassembly.ĭespite the best advice from armchair commentators, this can be achieved at home without a clean room. Upon analysis, concludes that the drive is not spinning up, and suspects the heads may be stuck, causing the problem. The video begins with plugging the non-functional drive into an external caddy, and using a microphone to listen to the sounds it makes. However, this is Hackaday, not HireSomeoneADay, so ’s video on do-it-yourself hard drive repair is just what we like to see. ![]() When it comes to data recovery, there’s always those bleating from the sidelines that it’s a job that must be left to the professionals. Hard drive failures can be tough to bear, particularly for the average person who doesn’t back up.
