HFS. The drive was formatted from the 7.6.1 install disk.
I figured out what it was. The deal is this: You actually can't mount a 2GB drive on a Mac IIci. I don't know whether it's a IIci/68030-specific limitation or whether HFS just peters out just shy of 2GB due to address limits (I am guessing the former). I resorted to splitting the 2GB drive into two 1GB partitions and they mounted just fine. It's not precisely what I wanted, but it gets the job done.
Best,
John
