Sometimes it`s possible to recover some information from a diskette although it`s damaged or corrupted. For this there are programs like MediaHeal for Diskettes 1.0 which examines and scans the undamaged sectors of the diskette allowing you to extract the information stored there.
It doesn`t only recover the information but also in some cases lets you completely restructure the tree of the data stored there, enabling you to locate a file by name.
If you think this program is useful you might be interested in this other, MediaHeal for CD and DVD
