I have a Mac Pro 5,1. Is it possible to add or remove a hard drive in the bays while the power is on? My mac Pro is currently running, the lid is open, and I'd like to re-insert one of the hard drives without powering down.

I don't see why this wouldn't work, as I do it all the time with external bare drives through eSATA. But I just want to make sure that the internal hard drive bays do not work differently.
