In many ways, the computer is
like a big appliance or a car, you can't imagine going on without it. If
the hard drive fails, you may very well have to face being without your
computer, at least temporarily, and you may lose valuable data. The fact
is, most hard drives fail sooner or later due to one or more causes.
Your computer's hard
drive, like many mechanical components with moving parts, is prone to wear and
tear. The older your equipment is and the stronger you use it, the closer
your hard drive is to eventual failure. Leaving the computer on constantly
increases wear and tear on a hard drive. If the unit is suffering from
wear and tear, the signs will be obvious, or rather audible. Buzzing,
grinding, and clicking are warning signs that your hard drive has seen better
days and a crash is coming.
Hard drives are among
the most vulnerable components of your computer. Dropping the computer can
certainly cause damage to the hard drive, especially if the computer is running
when the fall occurs. Overheating from dust-plugged conduits is another
source of physical damage to the hard drive. Excessive vibration may
initially cause minor damage that you can't even notice, but over time, the
damage accumulates, resulting in damage to files or bad sectors (unusable
sections of your hard drive) and eventual hard drive failure. .
Electromagnetic exposure
from items like your cell phone can cause hard drive damage. Static
electricity and power surges are also common causes of hard drive failure and
damage. Always ground yourself before touching the hard drive. Even
the back of the speakers can cause electromagnetic damage to your
equipment. If the computer doesn't recognize the hard drive when trying to
boot, magnetic damage may be the culprit. In many cases, a data recovery
service will be able to recover
the data from your drive.
Viruses and malicious
programs can cause essential sectors of your hard drive to be overwritten,
making it impossible for your computer to correctly read data or even boot at
all. Incorrect formatting of your hard drive is another cause of hard
drive logic failure. Software conflicts or corruption can also cause the
hard drive to crash. If the computer recognizes the hard drive, but
doesn't boot, it may be dealing with the hard drive logic failure. You
will most likely need a professional to recover the data from your drive
in this case.
