This is only on the IBM PC Bus controllers that have bios roms for
controller identification. OEM'd WD100x's like those in the Kaypro and
Perkin-Elmer 7300/7350 Unix boxes do not have this feature (or
the debug program to use it).

If all else fails you may want to try a low level format on the hard
drive. Boot with a MS-Dos ver 2.10 or later, run debug. At the '_'
prompt type in g=c800:5 which should access the controller rom and
enable you to low level format (it is <crudely> menu driven). Your
Tandon has 306 cylinders, 4 heads and 17 sectors per track. After the
low level format procede with the high level partitioning and
formatting.
I'm not familiar with the Kaypro 10 HD Controller but I am guessing it
uses a WD HD controller. One of the things I *always* do before using
debug and the "g=c800:5" command is to unassemble that location first (u
c800:5) to make sure it contains a jmp instruction. Other locations
that I've seen include c800:6 and cc00:5.
