There are plenty of articles on the internet that provide you with many ways you can attempt to reclaim data from a dead or dying hard drive. Everything from putting the platters in a new drive casing to bagging the drive up and placing it in the freezer for 20 minutes. These all seem to be fairly extreme measures to me, so here’s a quick tip I have discovered recently by accident which may help.
I have a number of old drives I have been using as storage, and I recently needed to access a file on one, and when I plugged the drive into my USB dock it spun up but would not mount. I re-tried several times and it refused to load. Needless to say I was pretty unhappy. I kept coming back to it over the next few days, trying again and again, hoping it would mount so I could “just get that one file”. A few weeks later, whilst having a clean up, I decided to give it one more try and if it didn’t work, I was going to throw it away.
I plugged the drive in, it spun up, and again it refused to mount. At this point I was called away quiet urgently, and I left with the drive plugged in and turn on. After about 4-5 hrs I returned, and found the drive had some heat in it. Wondering if this might yield a result I switched off the drive, then switched it on again, and it mounted, and I was able to get the file!
I seized the opportunity to copy off all the other data on the drive, and then I started to wonder…
I had two other drives that I had deemed dead in the past, so I plugged those in and left them to warm for a few hours. After restarting them, both of them mounted as well. One mounted and appeared to work well, but the other mounted just long enough for me to drag a few files off, and then it ejected itself again. In the week or so since, I have been able to reconnect and use two of the three drives normally.
I’m wondering if tarnish might have built up on the read/write head over the period when it was not in use, and a little bit of heat might have been all it took to break it down enough for it to be able to read again? Either way, if your drive spins up but wont initialize, this method might be well worth trying before you take extreme action.
