Hi Dave

To find out if it is not broken -

Try this -- safely unplug external drive > close down > wait 20 secs and reboot > then plug the two cables into the computer first then into the External Drive last - this si opposite to the printed instructions - sometimes it takes some time to recognise so be patient

I have transfered the contents of the black box to a bigger and robust hard drive

If you have a partition program like Paragon Partition manager open it and you will see an unassigned drive - assign a drive letter to it and it will work
