![]() Shockingly, it ran for a few hours while I recovered most of the data. The most awesome recovery I managed to date was to open a drive and unstick the spindle with a screwdriver and pliers. How that help got to be professional is by reading and trying stuff with disks they didn't care about. The Data Recovery experts tell you not to do this, but "seek professional help". It rarely helps, there are so many forms of failure, that it's a crapshoot. I've done this with known good USB enclosures and operated the drive while it was inside the closed freezer (with my laptop on the kitchen counter). Question: Is freezing a legitimate strategy to rescue data from a dying hard-drive? Or is this simply a fancy way to definitively brick your disk?Īnd if this is legit, should one attempt it before trying ddrescue, after trying ddrescue, or should I combine the "freezer trick" with ddrescue (and an associated log file)? Keep the drive upside down while you back up your files.") Grab the ends and physically spin the whole unit around", "just spinning the unit sharply along the axis of the blades" and (2) "In situations where the head has crashed, you can temporarily get it up and running by turning the drive upside down. (As per a now-deleted post Harddrive in the freezer ever work for you? on SuperUser, two alternative-medicine remedies to try before freezing are: (1) "Place the hard drive on a smooth surface. ![]() When it does, redo the procedure until all data is copied or the drive dies. At some point, the hard drive will fail again.Then connect the drive to the computer and start copying data.Leave the hard drive in the freezer for at least 12 hours.Place the wrapped hard drive in the freezer.(Use two or even three bags, and note that the bags do NOT need to be isotherm.) Place the damaged hard drive inside a ziploc freezer bag, so that no moisture gets in.The crux of it is as follows (but do read the full instructions!): on AskDifferent, on Unix SE, on AskUbuntu). Now I have read in several places about the " freezer trick" (e.g. ![]() The drive was dropped while the system was running and while foolishly I was trying to run testdisk on it, I started hearing-what I assume is-the " click of death". In the case of hardware failure, you should really hope that you put a backup somewhere, as even professional data recovery can only get you so far.I'm currently in the business of recovering data from a damaged-and dying-hard-drive (check this question for background info). In the third case, mileage may vary, and your program won't be able to get everything back, if any at all. In theory, good file recovery software can easily recover from the first two, with a little work (file names and locations may have gotten lost, but the data itself will still be intact). While some files may be able to be recovered (especially if the damage is limited to certain sectors), you may not be able to get all your files. If file data itself was overwritten (or certain sectors failed), then the files will be damaged.That said, the files should still be intact. In other cases, the entire partitioning table was overwritten.In this case, a good program can usually access them as long as nothing was overwritten. In these cases, the files still exist, but the computer doesn't know how to read them. the differences between NTFS, FAT, ext, etc.). In some cases, the partition scheme data was damaged (i.e.Recovery software is generally designed for the following instances: Disconnecting the drive and seeking professional data recovery services would be your next step. ![]() Even trying to read a damaged drive can cause further damage, as you can't really rely on read operations not accidentally changing something anymore. Software recovery usually causes more harm than good in these cases. ![]() First of all, as pointed out, a clicking hard drive usually signals hardware damage (although how a data transfer could trigger that is beyond me). ![]()
