The logic behind this is presumably that even if a sector cannot be read normally, it may still be readable with data recovery methods. 'Typically, automatic remapping of sectors only happens when a sector is written to. So SeaTools would not do any special proprietary thing to reallocate sectors or rescue your data, but just do something to trigger the disk's firmware's standard procedure for sector reallocation, as explained by Wikipedia: This seems to mean that SeaTools for DOS just tries to write to the bad LBA, which will then trigger it to be reallocated to a different physical sector by the drive's firmware. Usually, this action will assist the disk drive firmware in managing the problem by retiring the problem LBA and activating a spare in its place.' If you give permission to overwrite a bad sector SeaTools will attempt to write a pattern of zeros to that sector. 'If you have decided that the file or folder is replaceable, already backed up or just not important to you, then you can tell SeaTools to attempt to overwrite the sector. The SeaTools for DOS documentation reads: This is actually remapping the logical block on the hard disk not to this sector, but to a spare one. When using 'Basic Tests -> Long Test' in SeaTools for DOS, it may find bad sectors if there are any, and finally (after one info screen) present you with a list of them and the option to 'repair' them.
