When performing hard drive data recovery, it is often a physical problem that requires the disk to be opened. We open hard drives in our clean room to prevent dust and static charges to interfere with the media. Our most commonly faced problem is head failure. The heads float on a tiny cusion of air that is generated by the spinning platters. A brown out or drop in electricity or excessive heat can make the heads impact on the platters. In external hard drives, being dropped or suddenly losing power can also cause an impact.
Every now and then the heads will impact on the platters and cause scratching. This is as bad as it gets as the scratches are eliminating ones and zeros. In the photo below, the scoring of the platters is on the very edge of the media. This cuses severe damage to the heads which have to travel over the edge of the platter at every read and write. Even if we replace the heads, the new ones will soon become damaged as well.
