Resurrecting Dead Harddrives?
Broue Master asks: "The main harddrive of a friend's computer stopped working. He described to me that the computer began by emitting strange 'scratching sounds', and after a while, it made a 'loud *tock* sound' and stopped. He tried to reboot it but soon realized that the harddrive wasn't spinning anymore. He asked me if I could revive it, at least long enough so that he could retrieve at least his "my documents" folder. The computer was running XP. I did a little googling(tm) of my own to find out that the most recommended solution out there seems to be 'freezing' the harddrive for a day in a ziplock bag. I'd like to know what fellow Slashdot readers have done in the past to try and resurrect dead harddrives and if the freezing method would still be a good idea, today. The harddrive is a Samsung 30Gb." A good 95% of the time, once an HD is gone, break out the shovel, because it's time to bury it. Still, it would be interesting to note, if only from an anecdotal standpoint, if any of you have managed to perform such miracle hardware resurrections. Have you managed to revive a dead and decaying drive from the dead long enough to pull data off of it? If so, what did you do?
This can be a (very) temporary fix with a drive that's having problems with the electronics. Often if components are flaking out but haven't actually fried, they'll run when they're cold but die when they heat up. Get it cold and then power it up and work fast. You'll probably only have a few minutes at a time though. The same applies to motherboards, chips, and memory. To give you more time, you should probably set everything to as low speed and low voltage as you can get away with. I actually did this with a machine outdoors in 15 degree weather once. The machine had been crashing during boot and I couldn't get another machine to recognize the drive's data format ( it was a strange integrated controller on the motherboard ). Outside it booted and ran for two hours while I copied all the data over a long ethernet cable I'd ran out a window. Turned out to be the motherboard. After a replacement with something a little more generic and a reformat, I copied everything back to the drive and it was fine.
Granted this probably has nothing to do with your current drive problems. It sounds like it blew chunks with physical problems. Even if you could get it working again I'd bet you've got significant platter and/or head damage and any data you could get off it would have serious corruption issues. Scratching noises and loud thumps coming from hard drives are never good things.
