@icescout27 Sorry for the delayed answer. Somehow I lost track of this. OK, so now we see a different error, obviosly because the password of the fogproject account is different. As well the access rights of the folder seem strange.
Run sudo chmod -R 777 /media/fog/External and follow George’s advices and you should bei good to go: https://forums.fogproject.org/topic/11203/resyncing-fog-s-service-account-password
Those accounts are service accounts created and used by FOG. If you mess with those you will run in trouble sooner or later.
