If we still haven't done so, all of us will have to deal with a hard drive failure sooner or later. Most of us have had experience on hard drive recovery as well. A failing hard drive is one of the worst nightmares a computer user can ever experience. Added to that are the costs to recover your data. The cost can sum up to somewhere between hundreds and thousands of dollars, depending on the level of damage done. That much, just to repair a single hard drive. There is however, a good reason why the process is so expensive. It is not simply because we pay a huge hourly rate to computer technicians. The reason is because the process of restoring of data on a failed hard drive can be pretty tough.

The first thing that data recovery specialists try to pinpoint is the extent of the damage to the drive. If the computer was attacked by a virus or if the cause of the data loss was due to malfunctioning software, hard drive data recovery is not as tough as when the hard disk undergoes mechanical failure. In the case of a virus attack or a software problem, the computer's operating system is no longer able to identify the corrupted data. A professional is needed first to separate the data down to its binary form and then to bring it back to a format readable to the OS. The process is less complicated than if the damage was due to mechanical failure.

A hard drive is the only moving part in a computer with the exception of fans. When one of those moving parts fails, and they are prone to do so because they are very delicate, replacing them is a difficult prospect. First, not just any part will do. The data recovery team does not simply have a box of replacement heads lying around for every hard drive ever made. The pieces must come from a hard drive so similar that it may have been made at the same time and in the same factory as the damaged one. Finding and buying that specific hard drive can be costly. Then repairing the old drive and getting it running also costs a lot.

The most expensive part about recovering data from a damaged hard drive is getting it running again. Rebuilding all corrupted data can be cheaper and simpler. However, if your drive has been severely damaged, expect to pay a larger bill. Cases like this call for a rebuilding of the drive size, the number of files to be recovered as well as the date to be rebuilt.

The best thing you can do is to prevent these problems from taking place. Yes, even the sturdiest hard drive will fail after prolonged use. Nevertheless, if you back up data often, you will only need to worry about replacing the drive and not the important files.
