Hard Disk Bad Sector

There is no way to actually remove the bad sectors. Programs such as Scan Disk(which is included with Windows). Mark the bad sectors so that data is no longer stored there. Sometimes Scan Disk will find a bad sector while running and ask you whatto do with the data that is currently on that sector. It will write the data to a new location but the data may be damaged or may be recoverable. Once identified that sector will no longer be used so no further damage should occur.

The type of hard drive is important. You can download a hard test. From the manufacture such as maxtor...etc. This is a little better than windows scandisk. It does not fix the problem only to tell you that you have bad sectors. However if the computer/hardrive are still under warranty then you can get a replacement. If not the best bet is to purchase a new hard drive. Boot in safe mode, then use ghost software to copy the image over to new hard drive. If booting to safe still finds bad sectors and will not boot. Throw it out.
And start out new.

There's no software that will physically repair a damaged drive. The best that you can do is mark the bad sectors as unuseable and work around the defects that have developed. Know that once a drive starts developing bad sectors, it is only a metter of time before the entire drive will fail. I'd recommend that you purchase a new one and start over.

However, if you must mark these bad sectors, there are utilities such as Norton Disk Doctor that will mark these sectors as bad. There are also uti8lities that you may be able to get from the drive manufacturer free of charges to mark these bad areas as well.

If the hard drive manufacture offers one, a low level format utility will either recover, or permanently mark bad sectors as bad.

Alternately, if you delete all partitions with fdisk, and re-partition and format the drive, any bad sectors will beplaced in a table of sectors to ignore.

If your desire is to recover some data from a bad sector, forget it.
Unless the data is very valuable, the cost of a data recovery service is prohibitive.

As other posters have stated, it is time to replace the drive.
