Every computer uses file system to store and organize the data stored on the storage media such as hard disk, flash drive, CD, DVD, optical drive etc. In other words we can say that a file system of your computer is basically an index or database which contains the physical location of each and every piece of data on the hard drive. Thus, the file system is responsible for storage, manipulation, retrieval, and organization of data and information from the hard drive. Hence, any corruption or damage to it may cause inaccessibility to your precious data and thus cause severe data loss. In such critical situations of precious data loss, you are required to carry out hard disk recovery on immediate basis.

Different operating systems use different file systems such as Windows operating system supports various versions of File Allocation Table (FAT) file system and since Windows NT all Microsoft Windows system support New Technology File System (NTFS). While Mac operating system uses HFS, HFS+, HFSX, and HFS Wrapper file system. Hence, the stability of your computer system entirely depends upon the stability of its file system.

 If the file system of your computer gets corrupt then you will not be able to access the data stored on the hard disk of your computer because the operating system will not be able to find the memory location (address) where the desired file is stored. Some major reasons of file system corruption are:

• Improper use of commands

• Virus attack

• Improper system shutdown

• Power outage

 Basically the hard drive of your computer becomes RAW in the case of file system corruption and you require hard drive recovery to recover your essential data. Hard drive recovery is a process of scanning the RAW hard drive and extracting the data. However, the hard drive recovery is possible through specialized third-party disk recovery software. These are specialized tools which use intense scanning mechanism to penetrate the hard disk of your computer and thus recover your data.

 Most of the good hard drive recovery software have intuitive user interface and simple recovery steps which guide you throughout the recovery process. Having non-destructive and read-only nature these software are safe to use and recover your data without damaging or modification. Hard disk data recovery software can recover your lost, deleted, or inaccessible data lost due to file system corruption, virus attack, formatting or corruption of hard drive, etc. and should compatible with Windows 7, Vista, Server 2003, XP, 2000, and NT4 (SP6).
