Hello, My external hard drive work just this morning then when i went to access it the drive disappeared. now when i look for it, in the device manager, It shows up in the usb controllers as unknown device. when i plug in the firewire to usb cable my computer tries to recognize it but comes up as device not recognized. I run win 7 64 bit and the hard drive is a Lacie rugged 1tb.
