Oh wait. Rewind all of that.

You just said you did a hard disk upgrade with an 80 gig disk.

It's possible the builder image didn't work right. Assuming your music is backed up, then please run the builder image a second time and remember to press Enter in hypterterminal to the "disk appears to be already built" prompt. (I'm assuming that you were carefully following the disk upgrade guide and therefore know what I'm talking about already.)

If that doesn't work, then come back here and we can give you instructions on manually partitioning the disk.
