I recently download a backup program that deleted everything off my external hard drive. There is now basically nothing on my external, so I doubt any data was overwritten. I have a Western Digital 800BB External USB 2 with FAT32. I've tried almost every program I can get a freeware/trial version of and haven't had any luck. A few of them have shown me some of the files I am interested in but are missing quite a few I want. I've also tried restoring a few .avi files that did show up and all I get is a bunch of my mp3 files oddly strung together. Any help would be greatly appreciated.
