My dad refused to listen to me when I told him, what he was buying was in actuality a NAS and not a normal external hard drive, up until recently he thought all external drives were the same.
So, he gave it to me (Yay) problem was he had already set it up that every time/anytime it overheats and shuts down, he gets an email to tell him it has shut down, my dad has a hairline trigger for anger.
I updated the fans inside, as far as I know they are industrial strength, and the unit is no longer kept in a cupboard, it's well ventilated, but it still happens from time to time.
I have looked online and not found anything to remove/change the email address, without either wiping the unit or reformatting and starting all over again, plus he had no idea the setup process would be so complicated for him and made it so it only works/mounts as a Guest account there is no username or password.
