Physically Damaged Hard Drive

Or printed circuit board encounters short circuit. Also, the most common physical damages include bad sectors on hard drive. Here we’ll take bad sectors as an example.

Further Damage Will Be Caused

When you running recovery software on a hard drive, the drive will be powered on and the drive head will begin to work, reading information on the hard drive. Under this circumstance, the head will be forced to read a bad sector when you command the software to make a full disk scan or clone the disk, etc. However, in fact, the bad sectors are inaccessible. Thereby, the software will instruct the head to try it over and over again. In this situation, the head will get seriously damaged and scatter the drive platter severely. Without any doubts, further damage will be caused.
