Reason your wiped data
If you per misfortune a memory ticket knew, on which recordings stand that you actual wanted to keep, have you only a cool head and the right software necessarily your mistake undone to make.
The most important rule is: nothing do more with the memory ticket. If you it new recordings on placeest, are the chance particularly small that you ever yet something of the wiped recordings find again - unless you with real specialized equipment work, but that is almost priceless.
