I would guess the Adaptec has special BIOS code to fool DOS into
thinking there are 1024 or fewer cylinders. Some DTC controllers
can do this, but the WD1006V doesn't seem to be able to. There are
other workarounds, I think Speedstore and Disk Manager can do the
same stuff but that requires resident device drivers.
