Hi folks,first time poster,I have a maxtor 250gb usb drive that shows all data on the drive,can play mp3s and videos from it but when I try to transfer anything to or from my c drive the lights dim on the front of the usb drive and the data does not transfer. It has also caused some freezing when running programs from the c drive,when I turn the usb drive off the program loads right away. I also formatted recently and windows loading stuck at the windows setup screen until I unplugged the usb drive,then windows loading proceeded normally.Thanks,great forum!
