Drives not designed for 8
cm CDs. Drives fulfill
specifications.
If an adapter is used for 8
cm CDs, the thickness of the
CD increases which leads to
problems when inserting

Furthermore, there is the
danger that the 8 cm CD
will be pushed out of the
adapter while being pulled
in/ejected and thereby block
the mechanism.
