Recovering corrupted BKF file from external hard disk

I guess you must have faced loss of your precious data sometime or the other. And you would definitely agree that it is really frustrating to lose your data, which you may have maintained for years. Probably things would have been in better shape had you backed up your data. For this purpose, the Windows (2000, XP, and Server 2003) users have the option to backup the data using the in-built NTBackup utility. It saves the backup in the form of .bkf files and can backup from the tape, ZIP drives, floppy disks, and hard drives. However, these BKF files too can get corrupted because of virus infections, power outages, human errors, CRC errors, etc. In such cases, you should check if the original data is available. If yes, then you can create the backup again. However, if you do not have the data with you then you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you have a hard drive that has just gone dead. You replaced the hard drive with a new one. You used to backup all your data in an external hard disk using incremental backup mode. Now, when you try to use that backup to restore lost data you are unable to do so. An error message is displayed:

“The data file contains unrecognized data and cannot be used.”

The error message clearly suggests that the BKF file is inaccessible.

Cause:
The root cause of this issue is that the BKF file is corrupt. It may have gone corrupt because of the aforementioned reasons.

Resolution:
Now that you do not have the original data with you, the only thing that you can do in such situation is to use a third-party BKF recovery tool to repair BKF file. These read-only tools are highly interactive, and use fast yet sophisticated algorithms to scan the damaged area.
