IIRC the default for the root of the drives in Windows is an analog to Linux / which should be root:root 755.
The difference: When Windows displays the UAC dialog and asks you to elevate, it will (mostly?) just add your user to the ACL list instead of elevating your file browser while you access the drive. If ACLs are inherited from other folders below, that can have serious side effects…
