Hard Drive Crash? Avoid Making A Bad Situation Worse
If you experience a hard drive crash, it doesn't take much to
make a bad situation even worse. In the event of a hard drive
crash, in most instances, the data is completely recoverable at
first. However, as part of human nature, we often try to...

Hard Dive Failure: What Is A Head Crash?
No one likes the thought of losing all of their valuable data,
but a hard drive head crash is a definite data destroyer. While
a recovery is possible in most cases, sometimes destruction of
the platters is so severe that the magnetic material is actually
wiped clean. There are cases every so often where the highly
reflective, mirror type finish, of a platter is completely
destroyed leaving what appears to be a clear piece of glass
behind.
A head crash occurs when the read-write head of a hard disk
drive touches its rotating platter. The head normally rides on a
thin film of moving air entrapped at the surface of the platter
(some drives of the mid-1990s used a thin fluid layer instead).
Higher capacity drives (using the same size and number of
platters) are obtained by running the head closer to the
platter. A tiny particle of dirt or other debris can cause the
head to bounce against the disk, destroying the thin magnetic
coating on the disk. Since most modern
drives spin at rates
between 5,000 and 15,000 revolutions per minute, the damage
caused to the magnetic coating can be extensive, as the crashed
head drags over the platter surface.
Depending on the extent of the damage, your data may be
unrecoverable. Regardless, it's important to leave the recovery
to a data recovery professional, or you may risk losing what
data is still available.
One thing to remember, if you feel that you have suffered a hard
drive crash, shut the computer off immediately. Do not reapply
power to the hard drive. The longer the drive operates with a
head crash, the more damage that is occuring and the more data
you are losing.
