Hi Tony,
I sure haven't seen that error message before....Maybe someone else will pipe up that has seen the message with some advice. If I was in your shoes, I would build up a new hard drive with the OS and then copy your music (the large partition out of the 4) to the new drive from your existing hard drive (outlined by my post in the General section). Curiosity question: Have you been able to upgrade your existing drive to the new software release? I had trouble doing that on drives that had a lot of music...

Let us know how it goes....Thanks, Randy
