I currently have an iMac (OS X) with an AirPort extreme base station. I have a USB adaptor and two USB drives connected to the extreme. Every time I start Parallels/Windows XP the USB drives (network drives) get assigned different letters. Does anyone know if it is possible to assign permanent drive letters to the USB drives, so that when Parallels/Windows starts, the USB drives will always be, for example, the "X" and "Y" drives? Thank you in advance for the help/advice
