Ron bought a Western Digital Passport USB hard drive and he's having issues with it. Ron can see it in the device manager, but he can't access it on the computer. Leo says that a USB connected drive only means the computer can see the device. Doesn't mean it can read it. Drives do die, and sometimes they die sooner rather than later. That's why Leo recommend SSD drives for the main drive and a spinning drive for data. It sounds like his drive has simply died.
