Ignore what goes on on the screen. Services, 4, 0, 1, select. Now the installer menu appears. Same goes for all Sky Digiboxes.

got the special secret menu, but still no 'housekeeping'...............i therefore assume its either:
sky+ planner rebuild or
full system reset...............
and do i have to have a special handshake now?

sorry mate - planner rebuild defrags the drive and recalculates free space etc.
there's no need to format the drive (and no option to either)
