CP/M 3.0 (A.K.A. CP/M-Plus) does automatic disk logging as a matter of course.
It does this two ways - first by comparing the allocation tables of the disk
and BIOS, as suggested by Mr. Sage, and secondly, if operating with a drive
that can detect disk removal/insertion (by interruptions of the write-lock
photocell), by using that information.  And as Mr. Sage suggests, there are
some problems when swapping formats (this, on a C-128/1571 CP/M system), but
it largely works just fine.  C-128 CP/M 3.0 supports a virtual drive (E:), and
as expected, disk swaps to honor requests for the virtual drive do not trigger
the automatic logging.
