To index file system data, NTFS (New Technology File System) employs B+ tree structure to allow fast look up times. All the filenames are generally indexed individually in their own directory and with separate MFT entry, attributes, and security descriptors. NTFS users can experience critical data loss problems if NTFS indexes undergo corruption for some reasons. Such problems can be detected by unusual system behavior while accessing the corrupted partition. However, to deal with these issues, one may need to reformat the drive and restore the data from backup. But if no updated or valid backup is available, situations arise that can necessitate the use of NTFS recovery software.

Following is a realistic problem that will help you comprehend such problems in more detail. Consider one or more of your hard drive partitions are formatted to NTFS. When you try to access or open any of the NTFS partitions, it shows few or all of the given symptoms:

• You open 'Windows Explorer' and try to expand the NTFS partition, but the computer hangs

• On running chkdsk for the same partition, it reports NTFS index errors, such as below:

“Deleting index entry in index of file of file ”

• Some of the Windows applications fail to start because of missing files (.exe or .dll files)

Cause

NTFS index structure is damaged. This can occur for common reasons like, unexpected power outage, bad cables, and system issues.

Solution

Run system diagnosis to find out the problematic hardware. Remove it and see if the problem still persists. If this doesn't resolve the issue, check for the above mentioned BIOS settings. In case the problem still persists, NTFS structure is damaged.
