Subject: Re: TRS-80 Model II Fixed Disk Controller Support
That is if you're using external drives in the radio shack enclosure
with board types 2 and 3. The board in question here does not operate
that way. ST-506/ST-412 standard interface. Any bad track info already
on the drive is ignored. User has to enter it in diskutil. It is stored
on the partition that is created.
Try the drive in a PC and make sure it works first.

Some of the controllers also provided power on the
control?
Cable to power
on secondary enclosures.
Technical bulletins state that yes the cabling for a second drive is
modified to accomidate for the system to power on the
external drives by
means of a relay. If you didn't get the memo and you attached
a second drive
you would be greeted by a resistor on the drive burning out. :)
