Sounds similar to the original IBM 5.25
(and use HD write current) and I suspect that's why Steve's having trouble.

Sounds similar to the original IBM 5.25" format, single-sided, 512
bytes/sector, 8 sectors/track, 40 tracks, 250Kbps.

Yeah that does sound strange. And I agree, the drive 'should' switch based on
the hole in the disk. Does it format to 720 or 1.44 when the hole is covered?

The controller/computer probably can't handle the higher data rate of the HD
format (twice the DD rate).

Have you tried closing the HD sense hole with a piece of tape or similar?

the Coco is using it's standard controller
the Coco is using it's standard controller
When issuing the DSKINI 0 command the coco tries to format for 180kB.
The combination of
(Coco, std controller, PC 1.44MB drive + a 720kB dd floppy) works
whereas
(Coco, std controller, PC 1.44MB drive + a 1.44MBB hd floppy) does not work
this is
likely the floppy controller doesn't support 80 tracks or high density..
most of the controllers of the era are ds/sd 40 track or dsdd 40 track..
are you able to format 720k? ds/dd 80 track?

I have a Tandy Coco3 with a 3.5 inch floppy drive. The drive is a standard
PC drive and it is working well.
Seems though that I cannot use 1.44 MB floppies in that drive. They don't
seem to
