Emergency Data Recovery

Emergency  data   recovery  is the process of retrieving deleted and inaccessible  data  from the hard drive of a PC or laptop. A hard drive may crash at any time due to logical or physical failures, which include software problems, computer viruses, and mechanical or electrical malfunctioning.

Emergency  data   recovery  is possible because when a file is deleted, the operating system merely deletes the address or path of the file and treats the occupied space as free space. The file remains there until it is overwritten with new data. FAT (file allocation table) and MFT (master file table) contain details of all the files on the hard drive even after they are deleted by the operating system.  Data   recovery  software looks into these tables and recovers the lost files.

It is important to follow standard emergency  recovery  guidelines to avoid further damage to the hard drive and other components. The first step is to shut down the computer, remove the hard drive and send it to a  data   recovery  firm. There it is evaluated for cost and time of  recovery  and the client is informed of such within 24 hours. Upon approval of the client, the hard drive is cloned by making a sector-by-sector copy of the original drive. Lost or deleted  data  is then recovered using  data   recovery  systems and software.

Freeware can also be used to recover lost data. It recovers lost data in four or five easy steps. Users just need to execute the  recovery  freeware and select the drive. The software recovers all files and folders from the drive and gives the option of transferring these files to another hard disk or other storage media.

To avoid the high cost of emergency  recovery , it is important to create back up copies of important  data  onto a CDR or other storage media. Guidelines regarding hard drive protection and upkeep should be followed to prevent hard drive crashes or failures.
