Oh, and one more thing...
I suppose it's possible that I screwed it up, but I did partition my first empeg the same way, and I'm very comfortaible that I did do it correctly.
If your first empeg was a Mk1, then that might be the problem. As I recall, the Mk2 does something unusual with mounting the second drive to make it more compatible with the Mk1. I forget exactly what it was. Maybe this unusual thing is only in the init, or maybe it's in the partitioning itself, I don't know. But if you have your MP3s safely backed up, it can't hurt to try the official formatter utility to rule out any possible partitioning errors.
