I'm trying to add a SCSI drive to my A2500 - Quantum 105S. I defined 3 partitions in
the mountlist all of which MOUNT OK. However, only the partitions that add up
to around 50MB or so show up with the INFO command (FH2: and FH3: in this case). If I
try to FORMAT the FH3: partition (which mounted but didn't show up in INFO) I get:

		format failed 
		can't find handler

The mountlist entries are identical for each partition except for the LowCyl and HighCyl
entries and I copied these entries from the FH0: and FH1: entries already in there.

FORMAT bombs on large cylinder spans (400-500?) unless I use the QUICK option.

I tried defining 5 partitions which totaled up to less than 50MB total and they all came up
and formatted ok.

This drive uses zoned bit recording and so returns 0 (ZERO) sectors/track in mode_sense
page 3. Does the A2090a use this information?

I've heard that the old file system had a partition size limit, but I'm definetly
using the FFS here (DiskPerf assures me of that :-).

Any ideas as to what's going on here?
