So far there is no helpful solution to this problem. here is a link to my post as well...


It is nothing to do with the external drive but occurs when an upgrade has been done to the pc. in my case, from an internel 500gb SSD to a 1 tb SSD . using regular cloning methods.
All suggestions about reformatting etc are wrong, do not reformat if you have data you want to keep.
If you plug it in to a different pc or laptop it will work.
This is a real puzzle as no one seems to know why or how it could occur.

Good luck.
