Access control is not done inside Cygwin.  The permissions on the block
devices are set by Windows.  If you want to take a closer look,  see
the mapping of the native namespace into the Cygwin /proc/sys namespace.
Look at everything under /proc/sys/Device/Harddisk*, but make sure you're
admin, otherwise you won't see everything.  If you want to take an even
closer look, I suggest to download the winobj tool from sysinternal.  It
also provides a detailed ACL view.
