Usually this can be done by the disk-bios using the disk manufacturers disk

If there are damaged sectors then I would VERY STRONGLY advice to buy a new
disk.
A higher level (full) format, such as NTFS filesystem, *should* remap bad
sectors, but only *if* it detects them. You already know that you have bad
sectors, which means to me that you need to replace that drive.
