It's been several weeks since I've done anything with my TM-848E drives, but I
think that the behavior that Ali described is normal. As I recall, I have older
belt-driven (but still DC-powered) TM-848 drives in some of my Radio Shack machines, and
the newer ones with brushless hub motors that I use in my imaging setup. Both of them stop
the spindle motor when not in use, unlike older 8" drives with AC-powered motors that
run continuously.
