I chose to put this in BT becouse it is set up for Forensics & comes with Multiple Tools for the job.. this was jut 



 Today we will be doing a quick Forensics Analysis on a Blank Flash Drive with a bunch of erased Data 

so we will start out using testdisk =>

TestDisk is free data recovery software designed to help recover lost
partitions and/or make non-booting disks bootable again when these symptoms
are caused by faulty software, certain types of viruses or human error.
It can also be used to repair some filesystem errors.

Information gathered during TestDisk use can be recorded for later
review. If you choose to create the text file, testdisk.log , it
will contain TestDisk options, technical information and various
outputs; including any folder/file names TestDisk was used to find and
list onscreen.

Use arrow keys to select, then press Enter key:
>[ Create ] Create a new log file
[ Append ] Append information to log file
[ No Log ] Don’t record anything

so Create the new Log File & lets start recovering Data!

except for .Trash all of these are RED meaning they were deleted plus they all have Linux File & Directory Permissions by them !?!?
So lets move our Arrow to the .Trash-1000 =>
