There are many reasons why a computer user may experience loss of data – accidents, damaged disks, servers, and simply human errors.

If loss of data is a problem with the operating system, it is usually fairly easy to recover data with which to access the system and information on the subject, in general, to copy on another disk . But a failed or corrupted hard drive is a delicate problem of data recovery and in this case, often needs to repair the file or directory with a software to recover data. Sometimes, the hard disk itself must be replaced.

Given the risks to individuals and businesses to manage the hard drives and servers, most people opt for a data recovery service for all but the simplest of tasks to recover data.

A professional service begins with a physical inspection of a damaged hard drive damage with a microscope. The electrical components of a reader – as if, all, motor, servo circuits and interfaces – also taken into account, and his mail. If any of these components are defective, they will be repaired or replaced before the disk itself is reprogrammed, recalibrated and updated.

The magnetic media are subject to inspection, with technicians to research the function of read / write heads and to ensure that all are properly aligned. Again, all the faulty components are replaced, on the hard disk before being guide again, and remove contamination. The reader is then cleaned in laboratory conditions and reassembly.

Once the disk repair complete, it is possible, on the loss of data. All information on magnetic disks are read or extract the hard drive using proprietary programs.

The data stream itself subject to errors in the parity sectors and their codes CRC repaired before the data from the list of files are stored on secure servers in the enterprise.

Technicians, and the lists of files and data manually, customers or if it is necessary for the data for errors. Once validated, the data on a DVD or exchange the hard drive.

The original disk is kept for a short period after the restoration of data in case of problems, before the removal of all safety data are confirmed.
