+ 1 Votes Cable fault/port failure mjd420nova 1 year ago Try another USB port and check out a different port cable to the drive. The drive is trying to initialize but can't complete its start until the interface acknowledges the drive controller. It could be the port connector on the drive enclosure too. Either end if the cable is suspect. I have seen some USB ports fry traces off the port card(if you're lucky) or the system board itself.
