Its far from clear that there actually is an undamaged area of the disk.
If the fall caused some damage that produced a head crash when the
drive was used after the fall, there may well be a significant amount of
debris floating around inside the drive and thats whats producing the
symptom you are seeing of it become more and more inaccessible.

What do you mean by work ? Nothing will allow you to use the
undamaged area of the disk if there is no undamaged area of
the disk because debris is floating around in the drive.

There is no such animal if debris is floating around in the drive.

Thats a hell of a lot of reallocated sectors and has
likely exceeded the capacity of the bad sector map.
