hi i bought a maxtor basics 500gb external hard drive which was working fine until recently. now when i plug it in a message comes up saying "one of the usb devices attached to this computer has malfunctioned, and windows does not recognize it" . i plugged it into my laptop which runs with vista and it works fine. also i tried it in a friends xp pro and it works fine. i am running xp pro sp 3. the driver showing on my friends xp pro is driver version 5.1.2535.0 which i can't find anywhere online. any help much appreciated.
