I had connected a Western Digital 120GB Passport drive to my system. It has a usb interface. When I connect that to my dell laptop I am getting a error that the usb drive is malfunctioned. It is detected at start. I am having a Windows XP system. At the first time it was connected the drive was installed properly. I had copied some file. But this problem started appearing later on. It does not allow me to move heavy files from folder to other. Is there a way to fix it.
