def splitdrive(self):
drive, rel = os.path.splitdrive(self)<EOL>return self.__class__(drive), rel<EOL>
p.splitdrive() -> Return (p.drive, <the rest of p>).

        Split the drive specifier from this path.  If there is
        no drive specifier, p.drive is empty, so the return value
        is simply (path(''), p).  This is always the case on Unix.
