Ok so me like a dummy mistakenly reformatted my external harddrive...i've used a few recovery programs and was able to recover most files, but all the pic files i've recovered i can't preview, is there a way to fix this? and correct me if i'm wrong, but as long as i don't rewrite any data to this drive, i can still recover most files? i'm currently using stellar phoenix recovery software, anyone suggest maybe a better software to use?
