Reset NTFS permissions

Every time I reinstall my computer and then try to access my external hard drives I keep getting security errors and it won't let me access some of the folders.

After some research I figured out the way to reset the permissions on the drive:

  • Right click a problematic folder in the drive and press Properties.
  • Under Security press Advanced
    • Under the Owner tab:
      • Press Edit
      • In Change owner to: select the new owner (your user).
      • Enable Replace owner on subcontainers and objects
      • Press OK.
  • Close all of the dialogs until you reach the explorer dialog, and then open the Security\Advanced dialog again (after changing the owner you have to reopen it).
  • Under Permissions:
    • Press Change Permissions
      • Remove all NON-inherited permissions.
      • Enable Include inheritable permissions from this object's parent
      • Enable Replace all child object permissions with inheritable permissions from this object.
