What are bad sectors?
These are parts of the hard drive that cannot be read or written on for new data. The data stored in those sectors either vanished or got corrupted.
Bad sectors also contribute to major slowdown of the computer even in simple processes. They can spread if they are still used, eventually destroying the entire hard disk.
What are the causes of this problem?

When the disk inside the drive touches the head due to shock, it can lead to problems. Power outages that occur during data writing can also be a cause. Bad sectors caused by physical damage are called hard bad sectors, and they cannot be repaired.
Another cause of bad sector is the parity bits that got corrupted by malware, resulting in the data not matching when the hard drive is trying to read them. This is called a soft bad sector and fortunately, it can be repaired.
