Hard Drive Recovery refers to the physical repair of storage media that uses platters and read write heads. A hard drive has many moving parts that can at anytime break down. While it is true we need to repair the disk, we would never want you to use it again after hard drive recovery.
Sometimes a daunting task, hard drive recovery is best done within a clean room environment. It is not only dust that we must take of, but more importantly static discharge. Any type of outside influence can do more damage to the hard drive that already exists.
There are quite a few parts within a hard drive, many of them are moving pieces making the drive more susceptible to failure. The graphic below shows all the parts of the hard drive laid out:
Even though as you can see there are a lot of parts that can cause failure, most of the time it is the heads that fail. Here is a close-up of the heads and a platter:
Drives get shipped out with bad sectors, so that can be a problem, but we also run into quite a bit of spindle and platter issues. The larger the capacity the more data there is to be accessed, and the more work on the motor. While it is true we can completely replace the platters, see my wife Victoria’s post: Platter Replacement – Old News for more info, many times the problem is with the bearings. This is rampant in some laptop hard disks. Read Victoria’s post about Toshiba Laptop Bearing Problems for more information.
Here is an up close picture of the bearings:
