Surprised to see that my UD7, Windows 7 64 bit Pro:
Plugged in a running, externally powered SATA drive into the rear ESata/USB 3 ports. Nothing happens until I reboot!

Once Windows sees the drive, if I unplug Windows doesn't notice.
Arn't Esata ports hot-pluggable?
Under XP with a PCI Sata/Esata card all of this worked fine!!!!

anyone know better?
