3. Mechanical Failure Usually worse than electronic failure, mechanical failure can quite often (especially if not acted on early) lead to a partial and sometimes total loss of data. Mechanical failure comes in a variety of guises such as read / write head failure and motor problems. One of the most common mechanical failures is ahead crash. Varying in severity, ahead crash

occurs when the read-write heads of the hard disk come into contact, momentarily or continuously, with the platters of the hard disk. Head crashes can be caused by a range of reasons including physical shock, movement of the computer, static electricity, power surges and mechanical read-write head failure. Mechanical failure can usually be spotted by a regular clicking or crunching noise. It's not necessarily ahead crash, the most important things to do if you suspect mechanical problems is to switch off the drive immediately as further use will make matters worse.
