An error occurred while applying security information to: E:\randomfilename Access is denied.
I plugged in my hard drive to my lap top and when i tried to delete or move files access was denied because i dont have correct security. well when i attempted to change the security this popped up >An error occurred while applying security information
to: E:\randomfilename Access is denied. and wouldnt go away! I tried turning on the Admin account and then changing it but I still couldnt do it.
I had the same problem, that's what worked for me:
My mistake: Trying to deny access to all the users a part from administrators i had checked the box "Users" and deny all access.
But I foud out that teven being the administrator, I am also considered a "user", so even if the administrator has full rights, if he's also included on the users list he wont be able to access anything.
Similar mistake can be made by checking "Everyone" when setting the rights.
Solution: just go to the properties of your folder and allow full access to "Everyone" and also to "Users". I hope it helps.
