I don’t know of an application which will do what you’d appear to like Disk Scanner Pro+ to do (force the disk to allocate replacement sectors to replace any unreadable ones without affecting – e.g., wiping – the surrounding data). This is likely because lacking detailed knowledge of the way the file system is using the damaged sectors simply revectoring them elsewhere would leave any files (or, worse, any file system metadata) that had used them corrupted because the file system didn’t know the sectors no longer contained what they should and/or because the user might want to use an application like Unstoppable Copier to make a more thorough attempt to reclaim any missing data than the disk and/or operating system did.
When a 2 TB disk of mine developed some unreadable sectors several years ago I used a similar scanning facility in the free version of MiniTool Partition Wizard to find out where they were, deleted the partition which contained the corrupted area (and later placed a backup copy of the partition elsewhere on the disk), created a small new partition just large enough (4 GB) to isolate them (just in case they were the result of head contact with the disk surface I preferred to keep the heads away from them), and have used the disk without problems ever since (those Samsung HD204UIs made in Korea are almost immortal).
