How to recover or fix Hard drive bad sector

 

Hard drive bad sector is a common problem and it will cause hard drive crash in future. A bad sector occurs when there is physical damage to a part of the hard drive. Modern hard drives are created with many spare sectors. When the Hard disk controller detects a bad sector in the hard drive, it remaps that sector to another physical sector on the hard drive.

When we run a disk utility such as Scandisk and Norton Disk Doctor, such faulty sectors are marked with a "B".

As the hard drive bad sector is a permanent physical damage of hard drive, we can’t recover it by High level Formatting Like “Format” Command. Low level formatting is another option but Low level formatting programs and utilities for detecting bad sectors and wiping the disk not carrying out in such situation.

So bad sectors are not removed, but it will be in the table of bad sectors so that system can ignore those bad sectors.

Here I named some software for Hard drive bad sector Recovery, which is mainly manufacturer software Like Fujitsu (Erase, 33 KB), Maxtor, Quantum, Samsung (Clearhdd.exe, 11 KB), Seagate (Sgatfmt4).
