So, I have two laptops and two my passports. Both passports will work on my first laptop just fine, wont on the (new) second one. Installed my discovery, updated it, installed WD backup, wont recognize ether my passport. Strangely, WD discovery will recognize them.
I did get the passports to be recognized by maunlly transferring all of the western digital files, in the 4 locations i found(why 4, why not one T-T), program files, program 86 files, local, and roaming. Put them on the new pc back in their spots. Then it would recognize the existence of the my passport, but wouldn’t allow back up giving me some gibberish about this backup line already existing. EDIT: mess around with it some more, no progress.
