What causes a corrupted hard drive?

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

Improper shutdown. Suppose the power was abruptly shut off when booting up or the computer was forcibly shut down. In that case, it will likely damage the hard drive, causing partition table corruption, partition loss, or even data loss.

Dusty running environment. Dust causes considerable harm to the hard disk. Hard disks can easily absorb dust particles in the air, thus hindering electronic components' heat dissipation. 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 an exact structure.

◆ Virus and malware. For instance, CIH is a malicious virus that can harm the computer system’s hardware. Some users will find files automatically deleting themselves, which indicates your hard drive is infected.
