While backing up my comp, I tried copying over my iTunes library to an external HDD. After doing so, I unplugged the drive, and suddenly every song in my library has the dreaded exclamation mark to the side of it. I've used programs such as iPod Agent before, but they all seem to have a 5 or 10 song per transfer cap unless you buy the program, something I'm to cheap to do. Snyone know of any free programs that let you copy all of the music off of your iPod at once?
