At one point I was in the same position you are now in, and I found that the
only way I could do this was to format the disk on the IBM in SS/DS 40 track
mode.  This only allows for 180K per disk, but it works.

Another thing you could try is formatting it SS 80 track, and then copying the
boot sector from an IBM disk onto the Atari disk.
