How to Fix “D: is not accessible. Access is denied”

So, let us see what can do to gain access to the disk if we encounter the error, unable to display the current owner and see the empty Security tab (it won’t display any user groups). If you are already logged in to the user account with administrative privileges, you should do the following:

  1. Right-click the disk or folder and select Properties.
  2. Go to the Security tab.
  3. Click Advanced.
  4. Now you will see “Unable to display current owner“. Click Change
  5. By default Windows adds 4 user groups to the Security tab: Authenticated users, Administrators, Users and System. If you add just Administrators and System you won’t be able to normally access the disk and even read its properties such as used & free space even from accounts who are members of Administrators group except the built-in user Administrator.

Why You Should Not Add Everyone

There are several forum posts on the Internet suggesting to solve “Access is denied” error by adding “Everyone” to the permissions of your drive. We don’t recommend you to do so because in this case really everyone including guests (unauthorized users) will be able to access your drive. In some cases this can give you hard times. So, we advise that you added only those objects (groups and/or users) we mentioned above.
