External Hard Drive Wiped Itself?

#1 Post by shuagood » 06 Nov 2013, 16:29

Hello, I am new to the board, love what you guys do!

K so heres the deal...

I have an external usb hard drive that I stored most of my data on. One day I was loading files on it, and after I was done I got a bit excited and unplugged it before the computer was done shutting down. :roll: So I let the gf use it at her place, she plugs it in, the entire drive is empty, apart from a $RECYCLE.BIN and a system volume information folder. Either way, 500gb vanished somehow. I have been using testdisk to try and diagnose whats been going on, but alas, i'm not really too advanced with dealing with data recovery, or hard drives in general. I would play around if i didn't want the data, but photos of kids are kind of irreplaceable lol. Anyhow, ran testdisk, got a log file, maybe someone more advanced with this kinda stuff could possibly please help me out? Would be greatly appreciated! Thank you in advance!
