Question

Hard disks

What or how to recover broken files?
The situation is this, a disk has fallen off, something has been completely restored, something remains broken.
Mostly graphic files, about 300pcs.

If files are fragmented (which is a fairly common occurrence), recovery with the wrong tool will not allow you to recover files correctly, and it is not known what else was done and how the recovery took place.
The first piece of advice is to make an (accurate, raw) image of the "broken" disk and work only with it and recover data only from it.
