Planner cannot be rebuilt in Diskless Mode

Community Manager

If you have an issue recording or downloading a programme, the chances are you've tried to complete a Planner Rebuild. If you then see this message, "Planner cannot be rebuilt in Diskless Mode" it's because the Sky box isn't able to access to hard drive.


The two steps which are most likely to resolve this issue are; a Power Reset and Full System Reset. If neither of these work, it's likely you'll need a replacement Sky box.

  • Pop your Sky box on standby
  • Turn off the power to your Sky box.
  • After a few moments turn the power back on
    • Give your Sky+HD box approx. 4 mins before taking it out of Standby

Once your Sky box is back up and running, check to see if the original issue has been resolved, if not try the next step.



Full System Reset


As a last resort. A Full System Reset will permanently deletes all recordings, downloads, reminders and series links. You can restore copies of anything you’ve bought using Buy & Keep at


  • Press Services on your Sky remote.
  • Press 0,0,1, Select (Setup should be highlighted)
  • Scroll to System Reset, press Select
  • A confirmation banner will appear, press Select to continue.
    • Give your Sky+HD box approx. 4 mins before taking it out of Standby

The chances are everything is working as it should be, so let's re-add those series links Smiley Happy

Hi everyone, I joined Sky in 2011 and haven't looked back since! I am passionate about helping others and all things Sport. My favourite TV show changes all the time, but at the moment i'm re-watching The West Wing on Box Sets.

I have recently had to re-set my Sky HD box following a "diskless error"; I used the front panle re-set procedure from an earlier blog; the re-fromating has now been running for 14 hours and still going .  does anyone know how long this should take?

Hi @EPRed,


From start to finish, a front panel reset normally takes around 5 minutes (ish) to complete.

Hi @EPRed,


What specifically is happening?

Is your box stuck in standby?

What lights are visible on your Sky+HD box? Smiley Happy


Included within the approximate 5 minutes timescale i mentioned was...

Once the reset has completed, your Sky box will go into standby.

After 2-3 minutes, you should press the Sky button to take your Sky box out of standby.

Your box will start on automatically start on channel 998.

You should find all recordings/planned recordings have been permanently deleted.
