[long flame about DOS Mounter 2.0 and Syquests]

There may be an explanation for what you're experiencing.  DOS Mounter
2.0 uses the "external file system" hook in the Mac file system.  This
is an entry point which is called whenever the native Mac file system
doesn't recognize a disk.

Some drivers check that a cartridge is Mac format, rather than letting
the file system do that check.  They then reject a cartridge (or offer
to format it) without ever letting the file system call the external
file system hook.

If this is true for the particular drive you have,  then the message
you're getting is not DOS Mounter's fault; they aren't even getting
called.  The solution in this case is to try someone else's driver.
No, I don't have a list of these drivers.  

A conversation with one of the authors of DOS Mounter brought up this
problem (which I had also experienced when writing the High Sierra &
ISO 9660 file system translators for CD-ROM using the external file
system hook.)
