After multiple tries to backup my files, it just didn't work. I couldn't even move 2 files. So, in an effort to get my files out and after reading plenty of blogs about people with dying Western Digital MyBook drives, I decided to take the case apart and take out my hard drive:
At this moment, it is hooked on to my tower and going through disk check to look for bad sectors and corrupted files. It's been an hour and it's still going. I guess that's normal since it's 160 Gigs of space to go through.
It seems to be running okay, but we'll see when it is done scanning.
