This one I can answer, because I first had this problem with my Intertec
Compustar (relatives of the SuperBrain).  I found I had to format the 
Compustar disk on the DOS machine with 22Disk's CFMT /com3 Du: command,
but then could easily read and write the data from the Intertec computers.
The CP/M machine does not write the proper header on the DOS disk for the
DOS machine to recognize that there is a disk there.  

Try to format the disk on the DOS machine, and then copy files to it.  I have
had beautiful luck with this technique.  (Kaypro format works fine from the 
Kaypro, it must set up the 'boot track' that the DOS machine recognizes that
it has a formated disk in it).
