Common reasons for hard drive corruption

A hard drive won’t die for no reason. Check for the triggers as follows to see if you have run into the same or similar situation.

Improper shutdown. If the power was abruptly shut off when booting up or the computer is forcibly shut down, it is very likely to do damage to the hard drive, like causing partition table corruption, partition loss, or even data loss.

Dusty running environment. Dust causes considerable harm to the hard disk. Hard disks can absorb dust particles easily in the air, thus hindering the heat dissipation of electronic components. Then the hard disk may get burned because of the electric leakage.

Wear and tear. After a long period of use, the platter and the head assembly are prone to wear out, especially the head assembly with a very precise structure.

Switches Meaning Supported mode(s)
/n Filter the scan range: scans for a specific file with its file name/path/type, etc. All
/y: Recovers specific extension groups. Signature

/segment Segment mode; recovers files under NTFS drives using file record segments. Segment
