My External Hard drive wasn't working. Having used different power cables I tried connecting it directly. I opened up the case un-mounted the drive from the PCB and connect the drive directly using a SATA to USB cable. On connecting to the computer it installed as a Mass Storage device and is supposedly working correctly, but I cannot access it via My Computer. in need to get on the device so I can retrieve all my data that was backed up onto it. in short I have power to it but no access
