There are no guarantees here as the "overwriting" of data may have damaged the underlying files. You might want to try the File Recovery program from the link below:
PC INSPECTOR? File Recovery
Hope this helps.
Is there any way to "undo" or "restore" a floppy disk to the state it was in before I decided to copy something from another floppy disk to it? It was after the fact that I read that all information on the destination disk would be erased.
