You don't fix bad sectors, you replace the hard drive. Once bad sectors appear they only spread until the drive is no longer usable, and, may result in loss of all data. Your only option here is to back up your data and replace the drive.

Remap the bad sector?
Remapping manually is like putting lipstick on a pig. When a drive is manufactured, a large number of sectors are marked as spare. This pool of spare sectors is calculated to last the life of the drive. When the drive's firmware detects a bad sector it uses one of those spare sectors to map out the bad one. This happens invisibly. When those sectors actually become visible it means that the spare table is now empty and no spares exist. This is the mark of a failing drive. It will only get worse. Replace the drive now, while you can still retrieve your data, otherwise you will be right back here, in a couple of days, weeks, or months asking how to recover your data from the now failed drive.

Actually, I would liken it to putting a bandaid on a sucking chest wound.
The patient is going to die. You're just extending that a day or two.

Back up your data, now, and replace the drive.
Before it fails completely, when it decides to.
