[Coco] drive motors

Robert,
For RSDOS you want to use single head. RSDOS will not read a double sided drive.

Found my problem.  Went through all the shelves, found 4 different 
floppy drives to test, found one that works, the others do not. Possible 
that newer floppy drives no longer properly support DD write?  Who 
knows.  Very happy it works now, and thanks for all the advice.

Another note, found this utility,:

http://www.hp9845.net/9845/projects/fdio/

Downloaded the zip toward bottom of page, installed it on xp, and was 
able to format (in theory) from PC however I like.  For example for coco 
I used command

fdio -format -g 35,2,18,256 -i 3

which I think corresponds to:

35 tracks
2 heads (double sided)
18 sectors
256 bytes per sector
interleave=3

Don't know much about it other than the arbitrary format option using -g 
seems pretty cool.  Did double sided to be safe, didn't have to...

using DSKINI, but yes, DSKINI will format the disks fine. They will just be 
formatted as 35trk SSDD disks. Unless you have something like ADOS or ADOS3, or 
are using OS-9, RSDOS will format ALL drives as 35trk SSDD no matter what kind 
of drive it is.
