Hard Drive Data Recovery



Data recovery can be tedious. The good news is data recovery, more often than not, is still possible. Data recovery can be done in either two ways: by using data recovery software or data recovery services. Data recovery software can help you revive the data which you thought was lost. However, data recovery services can do more than that.

So what exactly is data recovery? Data recovery, according to the word sleuths and data recovery experts, is the process of salvaging deleted or inaccessible data stored on damaged media like magnetic disks and computer hard drives, optical devices, and tape cartridges. Many data recovery software programs and data recovery services are designed to help users retrieve their files at the event of a computer crash or viral infection.

How does data recovery work? The first step of the process of data recovery service usually involves evaluation to determine the extent of the data lost. After the prognosis, the data recovery experts and technicians would then proceed in “cloning” or copying the media into their systems. The actual data recovery process occurs when the technicians secure and extract the data from the copy of the damaged media.


Hardware and software teams A damaged media has the data locked within it and it is the job of highly experienced hardware and software engineers to unlock it. These two teams of data recovery experts work very closely together throughout the project, combining all their experiences in their respective fields to solve the problem quickly and surely.

For safety measures, hardware engineers access as much of the disk as they can to produce the copy which they then share with the software specialists. The bulk of the data recovery process lies on the software team as they are the ones who do the actual extraction using complicated software programs designed especially for data recovery work. The ensuing data are then filed and written onto a new, undamaged media.

Before engaging a hard driverecovery service to attempt data recovery, it pays to know what a hard drive and hard drive failure are. A hard drive is a stack of discs coated with thin layers of substrate and magnetic material. Hovering above the disc is the drive head. The discs create a slight breeze as they spin, creating a cushion of air for the head. The drive head, as a rule, never touches the discs unless something happens to that cushion of air beneath it. If however, the head touches the discs, it will drop through the magnetic layers and cut slashes into the surface of the discs. It grinds through the aluminum substrate and sprays dust from all three layers all over the discs. The result is hard drive failure.
