Hard Disk Recovery Essential as Computer Memory Gets More Complex

Nowadays, just a few hundred pounds can buy trillions of bytes of data storage – an unthinkable amount just a few years ago. With this comes the ever-present risk of hard disk failure though, and the need to have access to an efficient hard disk recovery service.

If a hard drive fails even for a home user, it puts at risk thousands of valuable files, such as personal photographs and music. For a business relying on safe data storage, the risks are multiplied a thousand fold, especially when one realises that a new drive can fail just as readily as an old one that has seen heavy use and research has suggested that business sector failures are the most common.

Computer professionals involved with hard disk recovery have reported that the most common causes of failure that they see are down to human clumsiness – such as spill damage or dropped laptops. Failures due to surges of electricity are also routine. Over time, the sheer fragmentation caused by using the hard drive will create “bad” sectors which are prone to corruption or crashes.

Frequently, users accidentally delete important data. In the latter case, 100 per cent of the information can usually be retrieved. Hard disk recovery technicians have also revealed that they are being approached by a growing number of clients who have had problems with USB memory sticks – again usually due to physical damage.

The first step for the professionals is to create an exact image of the media stored on the disk. If this cannot be done, it strongly points to complete hard drive failure, and the disk – plus all its components – needs to be examined under laboratory conditions. Such “clean rooms” have air-cleansing systems that keep the atmosphere free from dust and earthing devices to prevent the build-up and discharge of static electricity. Such discharges can be very harmful to a computer drive.

When the components are analysed and diagnosed, strenuous efforts are made to repair the drive sufficiently to gain access to its data. The data can then be transferred on to a working disk in the form of a file list and the client can relax, safe in the knowledge that their information can be rescued by their virtual emergency service.
