Probably not a perfect test, but I've looked at the source for BDOS 1.5a
and MasterDOS 2.3.  The only difference in the physical format seems to
be MasterDOS using an extra three 0x4e bytes (27 compared to 24) at the
end of each sector, which it comments as "more time between sectors".
Might just be the PC being sensitive to that?

Alternatively, could you e-mail me the version numbers of BDOS and
SAMDOS?  It'll be easy to stop it in the track formatting code in
SimCoupé to compare the raw formats being used...

Si
