A hard disk file system is a method that hard drives uses to store and manage all the data it contains. NTFS is one such file system that employs index structure using B+ trees to locate the stored data. Once the file system gets corrupted, a user experiences issues while accessing this data and in worst situations, system might become completely unbootable too. Most of such problems can be detected at boot-time by Windows. When data is inaccessible, a user requires to restore it from the last available backup. But if it is not feasible to use the backup, it causes unavoidable situations of using a commercial Data Recovery Software.

File system corruption can be illustrated using different existing realistic problems. One of such problems is described below:

A user attaches an external hard drive to its Windows computer
The computer cannot access the hard drive.
Next, when the user runs chkdsk to check and repair the inconsistencies of drive, it reports the below error message:

"The type of file system is NTFS. Unable to determine volume version and state. CHKDSK aborted"

The data of the drive is not accessible to the user.


NTFS file system structure, possibly the indexes, are corrupted. The file system is corrupted to an extent that chkdsk cannot repair.


In such situations, a user is recommended to follow suggestions, such as:

User can try to re-run chkdsk using switches like, /f and /r
If it cannot resolve the existing problem, the user is suggested to reformat the drive and install a fresh file system. Since all the data will then be deleted, user needs to restore the lost data from backup
In case backup is unavailable or invalid, it is suggested to use a Data Recovery utility. These tools can scan a logically crashed media using powerful scanning algorithms and can recover lost or inaccessible data. Data Recovery Software provide a user-friendly interface that makes the applications easy to use by the user.
