I seem to remember that MDM offers a 16-sectors format, suppposedly for compatibility with TI's DD format. I never used it, of course.

The 16-sector DD format is supported by the Myarc DDCC-1 (early ones could only use that format, later ones could also do 18 sectors to make them compatible with the more popular CorComp controllers). The Myarc disk manager (and DSKU, IIRC) supports the format, as does TI's disk manager.

Yep... so DC needs some 320K HFEs to use with his Myarc. If he uses the Myarc Personality Card HDD with a Corcomp, there are potential data loss issues on the HDD, and we don’t want that. So, has to be Myarc 320K HFEs to copy Straight to the Gotek HxC.

Also, I’m guessing that if he tries to format 360K with DM2K, it might look like it worked, but really wouldn’t because that format has no idea.

Myarc was never spelled as MyArc.  On all their product manuals, it was MYARC.  I would either use Myarc, or MYARC, but not MyArc.  MyArc just does not look right.

Changed it  73  125 times in my main excel sheet ;)
