Mechanical Hard
Drive Failures:
Mechanical problems are can happen due to spindle
motor or bearings, such as motor burnout, "stuck"
bearings, excessive heat causing expansion in
the shaft and jamming, or motor coil burn out
or shorting. Problems like these are usually
rare but may happen to your drive. The most
common reason for failure however is head crashes.
The head floats only a tiny distance above the
platter on a cushion of air caused by the spinning
platters. A bump to the system at the wrong
time during head movement, the improper signal
causing the heads to jerk the wrong way or collapsing
of the air cushion can cause the heads to slap
the platters causing either physical damage
or magnetic damage to the platters. Noises such
as scrapping, grinding or that once in awhile
little ping may indicate a mechanical hard drive
failure. Another possible sign is the hard drive
spinning up and down or slower than normal spin
up at turn on. Clicking noise during starting
up or even during operation is also a very huge
signal that a pending mechanical failure is
coming.
