At least CD-ROM drives should have difficulties - there is no special medium
sensor, so the drive really has to try to read something [1] (with the
associated timeouts) in order to be sure that there is no disc in the closed
tray - however, most drives seem to handle this quite fast. However, if yoou
just inserted a disk with many sessions, any access may take quite long.

[1] Or at least try to lock the focus servo on the surface - but even this
may try for some seconds.
