Hello David, The disk is probably dead as suggested by the clicking sound. If you really want to recover important data which are only on this disk, I suggest that you open the USB enclosure and connect the disk directly to the computer. The USB controllers are usually not the best to handle defective disks. Cheers, Adrien
