When I set up my mycloud I made a mistake on my email. So when I try to get my password reset my account does not exist because it is wrong. If I do a hard reset can I start completely over with my real email address ?
You could perform a 40 second reset on the device and again setup it up using the dashboard. Please follow this article: https://support-en.wd.com/app/answers/detail/a_id/3600
