Heres how it goes... I use my external as a storage for a lot of important data. Just today, I turned it on and noticed the drive loaded, but, when I clicked on it, it had said "The disk in drive L is not formatted Do you want to format it now?" The hard drive was full to the 450gb mark! Hopefully this can be fixed without losing any data, I don't know what could have caused this to happen. Your help is appreciated. Edit: Right now I'm scanning with Data Lifeguard. Its going to take 4 hours, so Ill update when its done.
