that it would take weeks!  So unless someone can suggest a faster method of fixing the partition (mainly just as an exercise now) or at least just working out what is wrong with it, I guess I will just have to re-create the partition?

Since you have a very recent full backup, I would recommend just
reformatting the partition.  If the damage is that extensive, it's not
worth trying to fix it.


You are probably right - it would be an interesting exercise if it could be done though . .

There is no point in even trying. "Multiply claimed blocks" is an unrecoverable situation. Sure, each block can be cloned to give each file its own copy. The filesystem will now be consistent, but the some files will have corrupted content. Only one of those files (probably the newest one) claiming the block will hold its correct data. It's the job of _fsck_ to make the filesystem consistent, and not necessarily to preserve user data in the process. Having a consistent filesystem with corrupted file content is arguably a worse situation than a filesystem with known, detectable corruption.
