yes. I have done a lot of these.
Usually they combust in a blaze of glory.
15k rpm, 2.5 inch platters... run hot as hell.
the bearings wear out,
as long as they are spinning they keep working.
but once you turn them off you cant restart them - too much wobble.
The gyroscope keeps them smooth - till they power down....
I left one powered on the desk without a fan once,
hours later I grabbed it and scorched my hand.
