permanent fix is quite simple - this only happens if you're a little bit too slow at following the instructions to first of the instructions to take after flashing! This is because live pause is trying to write to a unintialised disk. Not to worry to sort this out......
Turn off the live pause by pressing MENU then go to Setup, Recording & Timeshift, Timeshift Settings, Now change the value for "Automatically start timeshift after" to Disabled and press GREEN to save. Use EXIT on your remote to get out of the menu. Change channel.
Now go back and follow the instruction for initialising your drive and check the mount point is media/hdd, then turn live pause back on and you're all set.
