No one who owns a computer ever wants to go through the process of hard drive recovery. Sometimes it is necessary if the hard drive contents are valuable enough. Drive recovery is the process by which important data are extracted from a crashed or damaged hard drive. Hard drives are generally very reliable devices. However, they are mechanical components with moving parts, and can fail for a variety of reasons. Electrical surges, wear and tear, fires, impacts and other drive crashing events can cause the need for recovering a hard drive’s data.
The degree of recovery needed by the hard drive depends on the circumstances. If the hard drive is still spinning but cannot access the data, sometimes a software solution is all that is needed. Professional drive recovery software is available that will scan the drive using sophisticated detection and analysis methods. These methods scan each sector on the drive for data, and use various techniques to attempt data recovery. If the drive damage is not too severe, much or all of the data can be recovered. The recovered hard drive data must be immediately transferred to a new, undamaged hard drive. The software recovery technique requires a hard drive that is still almost fully functional. If the damage is more severe, additional radical and expensive techniques are needed.
Specialty businesses exist for recovering data from badly damaged hard drives. It may sound unbelievable, but data can be recovered from drives that have been in fires, in earthquakes, or even shot with a gun. These hard drive data recovery businesses disassemble the hard drive in a clean room. The drive recovery technicians wear special suits to prevent them from adding any dust or contamination to the hard drive. The hard drive platters are analyzed with sophisticated machines that can detect and read the faint magnetic signatures on the drive platters. These magnetic signatures correspond to the files saved on the drive. In this painstaking method, recovery of a damaged hard drive’s contents can be partially or totally completed.
During hard drive data recovery, the computer from which the damaged hard disk was taken will be useless. The business that depended on that hard drive might have financial hardships. Those are reasons why multiple current hard drive backups are essential in a business or even home environment. Hard drives are reliable, but can fail just like any other machine. It is good to know that if a hard drive suffers a catastrophic failure, a hard drive recovery business might be able to retrieve the lost data.
