MSCP controllers do the bad block mapping, so AFAIK the disk _always_ looks
to the host like a linear array 0..n-1 of 512-byte blocks.
When accessing an MSCP disk, the host should not, unless running special
diagnostics, be able to distinguish what kind of disk is in use, aside from
that it has a particular block count.
