When a hard drive starts making unusual clicking noises, it is because the drive’s magnetic read/write heads have run into a problem while attempting to read data from its platters. Although this can happen for a few reasons, in many data recovery cases it is because the read/write heads themselves have failed and caused platter damage. Read/write heads are delicate instruments and are the most common failure points in a hard drive, whether due to physical shock or simply a result of natural wear and tear. Our Hitachi HDD recovery experts took a look at this client’s hard drive. We found that the read/write heads on the hard drive were mangled and had caused the drive some significant platter damage.
