Hi! If the hard drive and the Quattro are on the same bus (usb controller), I don't think there is any chance of getting that working. But, your computer probably has more than one usb bus. If the devices are connected to different busses, then it should work fine if the driver isn't crap. I haven't tried this, so I cannot confirm this though. At least on my motherboard, the usb plugs for the front panel are connected to one bus, and the ones in the back are connected to another one.
