I solved my problem with pdisk and more than a little help from Bruce Johnson offlist.
I used pdisk's '[capital] C' command, as Bruce suggested, to create a new volume. (You have to use the 'e' command at the top level in order to get to the C command.) I used the starting address and length in blocks of the already-existing free-space partition and I specified the partition type as "Apple_HFS". (The latter I copied from a partition map. I didn't guess!) When I rebooted, the finder gave me its unrecognizable disk dialogue, and since the size it specified was consistent with the new volume and not with any of my pre-existing volumes, I felt quite safe in formatting the volume. I did, of course, practice all this on a JAZ cartridge before risking my 'real' disk! Thanks to Bruce and the rest of you who offered suggestions. - Aaron -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
