Removing bad sectors from hard drives


What is the best way of removing the bad-sectors from hard drives, since it is making some cracking sound & the hard drive is 4 year old.

On a 4-year old drive it's best to simply replace it.

You can't really "remove" bad sectors -- and all modern drives will automatically remap them until the drive runs out of spare sectors [the S.M.A.R.T. system on the drive does that automatically].

The excellent utility Spinrite can sometimes repair sectors that are "bad" due to magnetic deterioration (not physically damaged) ==> it's as good as it gets for rejuvenating an old drive.    If you want to give it a try before replacing the drive you may get a bit more use out of the drive.   http://www.grc.com/sr/spinrite.htm

But if the drive's making noises and you're noting failed sectors, the best approach is to simply replace it -- a new drive will cost less than Spinrite ... and will almost certainly be appreciably larger than what you have now, so it'll be a nice upgrade.

There are too many variables to deal with. I don't think there is any way for you to do it but see these links for a better idea.


no more in production just replace it.

backup what you need and replace the drive.
you can always test the disk with the manufacturer's diag :  http://www.tacktech.com/display.cfm?ttid=287
this will give you it's status
and if you want to clean it - write zero's on the whole drive
