But what do you mean by "Sven's instructions are adequate (or, if you want to be on the safe side, mine up to first reboot)."
What do you mean by that? Does this mean I won't be able to use the 48gig as master and the 10gig as slave?

Exactly. If you follow Sven's instructions, 48G disk will have to be slave (and it also assumes that software will never use partitions other than hdc4 - music partition - from the slave disk; I think this is pretty safe assumption: otherwise, there would have to be separate versions of SW for single- and dual-disk empegs). If you want to be able to run the new disk as primary, you have to build all those additional partitions (in correct order, types and sizes). Finally, to actually use it as primary, you have to upload consumer or development software image to it.

BTW, why are you insisting on using it as primary disk? Is it going to be the only disk in the system? If so, then you should move everything in /driveX/fids (tunes, playlists and their tag files) from old disk ti the new one.
