Calcular uso del disco duro

[arrase]

Finalmente he resuelto el tema asi, por si alguien le interesa:

class DiskUsage:
    """ Clase que representa el uso de la capacidad de una particion """
    def __init__ (self,partiton=None):
        # Si no se define una particion se produce una excepcion
        if partiton is None:
            raise ValueError,'partiton is None'
        # Valores que representan el uso del disco 
        self.fs = partiton
        self.kb = 0
        self.used = 0
        self.available = 0
        self.percent = 0
        self.mountPoint = None
        # Capturamos los datos con 'df'
        self.parseDf()
   
    def parseDf(self):
        # Ejecutamos 'df'
        fh = os.popen ('df -k -P '+self.fs)
        # Parseamos la salida de 'df'
        while 1 :
            line = fh.readline ()
            if not line :
            break
            if line[0] == 'F' :
            continue
            line = line[:-1]
            lineTuple = line.split()
            try :
                self.kb = lineTuple[1]
                self.used = lineTuple[2]
                self.available = lineTuple[3]
                self.percent = lineTuple[4]
                self.mountPoint = lineTuple[5]
            except AttributeError :
                print "Fallo al obtener la salida de 'df'"
