The different device names are not the only difference between the "Tebby" 
and "MP" device drivers. Even the "MP" formatted disks have also the "QL5A" 
header, their sector organisation is a bit different. I have read about that 
a long time ago somewhere (can't remember where), but I unfortunately have 
no further informations about that.

"MP" formatted disks are readeble with any "Tebby" driver but not vice 
versa. Even SMSQ/E on QPC can read "MP" formatted disks (have tried that 
with the Utilities disk supplied with the MP I/F), but it is a bit clumsy as 
the SMSQ/E handler accesses the MP disk three times before loading 
something.
