Hi I had a freecome 80gig usb hd and it was working fine. I just purchased a 320gig maxtor usb drive. But when I plugged it in both doesnt work. It keeps saying usb device not reconized. I have wins xp sp2 and have installed all updates. I have searched on google for fixes but nothing works. Have removed all devices and tried but doesnt work. I also tried different ports but doesnt work. But when I plug the 2 hd in a diff pc it works. Anyone know how I can fix this error?
