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.
