I'm an idiot, I was writing an image to a USB drive using dd when instead of typing /dev/sdb I typed /dev/sdd and wrote the 135mb image to my 750gb External Hardrive full of files. Is there ANY possibility of recovering the files or did dd completely zero out the drive? Please help, as this is one of the lowest points of my life EVER.
dd finished writing the 135mb image in 5 seconds, so I didn't have a chance to stop it. By the time I knew what happened it was too late. The command was as follows:
The External Harddrive's filesystem was FAT32(I've had the drive for awhile and FAT32 was the most Universal FS at the time). I also have a 2TB drive I just got which I was planning on moving most of the files to from the 750gb, If needed I can use it to transfer the Recovered files to.
sudo dd if=generic.img of=/dev/sdd bs=1M
I posted this question on AskUbuntu(Link) and was advised to use TestDisk, however I've been having trouble understanding how to use the Tool(I looked at it's site Wiki and Documentation and couldn't figure out what to do for my problem). If someone could help walk me through the process I'd be very greatful.
