Sick hard drive given a second chance
Saturday, September 3, 2011 at 3:01PM Had a customer bring me a laptop few days ago because they couldn’t get it to boot up. It would get most of the way into windows, flash a BSOD (Blue Screen of Death), then reboot. That’s all it could do, safe mode, install mode, everything refused to see a useable or functional hard drive.
Now for those of you that have never had a hard drive fail on you, well first your very lucky. Second, you can’t really understand the frustration of having to recreate everything that was on the drive, assuming that recreation is even possible. Financial records are one thing but the only copy of photos taken of pets, family members, or vacations can’t just be recreated.
I really wasn’t looking forward to telling the customer that not only would they need a replacement drive (~$70) and a full reinstall of XP (~$50), but that all the data on the drive was unrecoverable. I always hate having to tell someone that, well any bad news really but the loss of a hard drive is particularly hard on most people.
So I’m faced with a hard drive that is essentially dead, a customer that will be none too pleased to hear it, and weekend to mull it over. Super. Course it took me a good couple of hours before my brain finally started working like it should and remember that I had a new piece of software designed to recover dying hard drives. Something I picked up a while back that sounded like a good thing to have around, could never play with it since I didn’t have any drives that were KNOWN to be bad. With nothing to lose I gave it a shot. Had to pull some tricks with a media card to get it to work on the computer but got it working on recovering the data and went to bed. A normal cycle takes about 20 minutes without errors up to 48 hours with errors, depending on severity.
Wake up the next morning with the cycle complete and the laptop ready to try windows again. The software had found a corrupted sector on the drive and managed to read enough of the data that it cold repair the broken components on the drive and function normally. The laptop presented me with a windows XP login screen just as it should.
Now the drive still has the corrupted sector since there’s no way to fix that, generally a problem with the physical components of the drive. But the drive works now. The closest equivalent in the human realm is cancer. It can be removed, irradiated, dealt with, and worked around but it never completely goes away until the part is replaced. The laptop is doomed to have this problem again eventually and there are other complications like slow speed, potential for data loss, etc but for the moment it has a second chance to function.
Of course I told the customer all this and urge them to start looking for a replacement laptop (it was quite old) or at least consider a replacement drive to backup all the data they needed to keep. Hopefully they will and in doing so avoid another malfunction that would cost far more than just the money to fix.
