Streetdaddy, the "first aid failed" message may be because of the circumstance Al posted on above: FAT32 formatting of the hard drive.
If that's the case, I certainly agree with Al that you have much to gain by correcting the situation. Transfer your music to a backup drive when you have finished following Herman's suggestions, above. Then partition the hard drive as I described in my own long post, using Disk Utility. Finally you recopy your music to the reformatted drive.
Use SuperDuper ( or Carbon Copy Cloner ) to do the first transfer and the second recopy. Just clone one disk to the other.
Once that's done, you may have to tell iTunes once more, via Preferences --> Advanced ( thank you Herman ) where your iTunes Media folder is.
Good luck and update us if you can.
