Data recovery sounds pretty simple on paper. When a hard drive or fails, data recovery companies simply rebuild the failed drive and transfer all of the information to another medium.
However, this simple explanation doesn’t exactly vibe with the cost of data recovery from a professional company. The average case can cost $1000 or more, which is why many data recovery customers have serious questions about the difficulty of the data recovery process. Many people assume that data recovery is quite simple, and even go so far as to attempt the service themselves. They quickly find out that they’re wrong (and down a hard drive in most cases, unfortunately).
Here’s a look at a few of the factors that lead to high data recovery costs, and why the process is too difficult for home computer users and repair shops.
Small Distances -The read/write heads of a hard drive read and write information (duh) from the data storing platters. While the platters of a hard drive are fairly large, the heads are small, and operate about a micron from the platter surface. This means that if the heads of a hard drive are jostled or moved–even slightly–data recovery becomes very difficult, if not impossible.
The trouble is that when you’re recovering a hard drive, you’re almost inevitably going to move the heads at some point. Data recovery engineers use precise methods and equipment to accomplish this, and they use specialized computers to double check their work and prevent errors that could cost you your data.
If you try to recover a hard drive at home, you’re going to find data recovery to be very difficult if you don’t have these special tools. That is, if you manage to get the hard drive open in the first place.
Data Corruption – The data on damaged hard drives often becomes corrupted, which is every bit as bad as the word “corrupted” sounds. Corruption can be cleared up through a variety of data recovery methods. In most cases, an engineer will work through data using special software, but this isn’t user friendly, click a button and it’s done software. It’s the kind of software that you need a computer technology degree to operate.
Overall, data recovery companies charge a lot for their services because they know that they’re worth it. Data recovery is too difficult for home computer users, and as technology progresses, data recovery becomes even more difficult. Ultimately, the price of data recovery is justified.
