Hard drive data recovery is the process of recovering data from damaged or corrupted media when it cannot be accessed normally.  Data can be retrieved from hard drives, FireWire drives, USB drives, DVDs, CDs, RAID (redundant array of independent disks), SAN (storage area network) and NAS (network attached storage).

Usually a hard drive may suffer either logical damage or physical damage.  Logical damage is due to corruption of operating system or file system, virus attacks and similar factors.  Physical damage is due to drive head crash and damage to circuit board, actuator arm, and other internal components of the hard disk.

It is highly important to have an efficient method of recovering your important data such as company particulars, legal documents, personal information and family photos.

Various methods exist for retrieval of data. We list the common ones below:

1. When the operating system or file system gets corrupted, your data cannot be accessed.  It's possible to recover the data with the help of data recovery software.

2. When data is deleted due to formatting of the hard disk or inadvertent operation, your data still remains intact on your drive.  Only the file indexes get deleted.  You should scan the disk drive to recover the data, and the recovery software can help you in this regard.

3. If physical damage occurs, recovery software cannot help you.  You will have to approach a recovery professional who will provide personalized service in repairing your damaged hard drive and retrieving the data from it.

Data file recovery software is user-friendly and can be used by any user without technical expertise.  But if physical damage takes place, you shouldn't try to recover data yourself.   It may cause further damage to the hard drive and may result in data loss which is permanent.

Efficient and assured data recovery demands solutions offered by a trustworthy and experienced enterprise.  A total analysis of the problem is necessary before deciding on a recovery process.
