What causes Western Digital HDD bad sector?

The bad sector means a tiny cluster of storage space that appears to be defective on the hard drive. When your Western Digital HDD has any bad sector, this sector cannot respond to read or write requests. Both the WD traditional mechanical hard drive (HDD) and modern solid-state drive (SSD) might develop bad sectors. The bad sectors can be caused by physical damage. In such a case, you can not repair them, just have to replace the bad hard drive with a good one.

However, you can apply some HDD bad sector repair tools to fix the bad sectors caused by some software errors. For example, when your computer suddenly shuts down because of a power failure and interrupts the process of writing data to a sector on the WD HDD, it might result in bad sectors. Besides, when the sectors containing data that does not match the error-correction code, there are chances that the sectors would be marked as bad sectors. Or the virus and malware could also lead to bad sectors.
