I have a venerable Heath/Zenith H-148 to which I am trying to add a
second hard disk. The first hard disk, which I bought from Heath a few
years back is a Kyocera KC-20A (20MB) with a DTC-5150 Rev E controller.
(I'm guessing on the controller. I know it is DTC, and those are the
numbers on the board.) The controller's jumpers are set in the Seagate
ST-225 position for both drives. The disk I am trying to add is a Seagate
ST-251-1 (40MB).

Using "prep/q" from MS-DOS 3.3plus and format from MS-DOS 5.0, I
have the ST-251-1 working just fine as drive 0 (drive C). The problem
is that whichever disk is disk 1 (drive D) is not accessible. The D
disk is accessed during boot, but an attempt to use "dir" or "fdisk"
results in a seek error. Chkdsk does its thing and reports the correct
information, but says that all allocation units on the disk are "lost".
I have not tried running recover, and have no other disk utilities.

I'm not going to expend too much effort getting this other disk to work,
but it would be nice. Any ideas? I have tried all four possible jumper
combinations on the controller for the second disk to no avail. I am
certain that the cabling and termination are correct. Which is confused,
the controller or the BIOS?

Anyone else out there keeping a 148 alive?

Thanks for any help. Please email and I'll post the solution, if any.
