As I said b efore the sound at reset is OK.  From your description it seems
that you probably responded YES to the question you get from prep about
whether you want the head parked after 3 (?) seconds of inactivity.  If you
did, re-prep the disk (which will wipe out all that is in there) and answer
NO to the same question.  On a ST-251 answering YES is really stupid, since
the ST-251 automatically parks the heads at shtdown. I don't know about the
Miniscribe.
