One of the most common computer problems I see people facing is a faulty or corrupted hard disk drive. In many cases, the solution to the problem is a reboot, and the OS automagically runs a utility like Windows’s chkdsk that repairs the errors.
Sometimes, the problem is a bit more severe than that and more drastic measures are required. Most people I’ve encountered were unnecessarily afraid of running any kind of tool to scan and repair their hard drive. But it doesn’t have to be all horror and blood and gore: with a little knowledge and a few specialized bits of software, you too can be a genuine Disk Doctor!
Now, this will not be an exhaustive guide to fixing all disk problems, cloning the data from a bad disk onto a new drive, and so on. That would take quite a bit of time to explain, and a lot of it simply requires some experience. What I can tell you, though, is how to diagnose a bad drive yourself. At least you won’t get taken for a ride by some money-grubbing repair shop if you end up needing a hand to finish the job!
