I put extra permissions on my external hard drive, but now i cant modify anything or add. i tried to change the settings to full control even though i am the admin and the security settings have a admin and my user name as two different users when my user name is the admin. i get it to change it keeps telling me it cant for every folder on the the damn hard drive. how do i fix it. i even removed everything and formatted it hopping it would fix it but it wont. HELP!!!!
