Perhaps an easier way if you have a Windows PC to hand.
Connect to PC in Storage mode, right click drive then select properties then tools & you get options to fix drive as well as defrag. I have used the defrag a couple of times.
Don't forget to set to Storage mode in PC link settings, does not need any PC sofware.
With the drive connected to windows thu storage mode, one would need to use chkdsk, or open disk properties and "check for errors" (same as chkdsk).
The problem I had above was with misplaced clusters. Defrag won't fix these, but the above method using, (disk properties and "check for errors"), will.
Most of the time if a hard drive has lost clusters or cluster problems, A defrag program will complain, and direct you to "check your disk for errors" first.
I preferred to use the "Linux" method, because I wasn't sure what was wrong in the first place.
