Raw Flash Drive - Testdisk Says No Partitions

#1 Post by lewy » 08 Apr 2014, 04:27

Hi,
My 2 year old son pulled out a cruzer edge while it was connected to windows. It is now showing up as a raw drive. I tried Testdisk (using Hiren's Boot CD), but it shows no partitions on the drive. Photorec cannot find any files and the same for other data recovery programs. Is there anything that can be done to get back all the data.
Thanks

Can you post a copy of testdisk.log file content ?

There is no FAT or exFAT boot sector, nor backup boot sector. It's very strange that PhotoRec has found no file.
Run TestDisk, Advanced, Image Creation, zip the image.dd file, if you get a very small zip, the content has probably been wiped when the key has been removed.
