Yes, the floppy drive is off when the HDM2 is in use. There are two power cables now inside my keyboard.

I don't know the exact power specs on the HDM2. My keyboard has been very stable with it inside. When you think of it, this device is merely a circuit board with a slot for a flash memory card and a very rudimentary switch attached to a cable. I cannot see how this could draw as much energy as a floppy drive that has something that spins around. I might be concerned with the hard drive based HDM but not with this flash card based system.

I'll be checking very soon to see if the system works with the new software, etc.
