Hi guys,

Sorry I'm a bit slow getting back, been a bit flat out. Thanks to both of you for your quick responses.

Darren -- you nailed it. It was exactly that, I had taken the disk out of my dead tivo and put it into another one. The "Clear and Delete everything" fixed it, good as gold now.

Chris -- From your description it sounds like it might have been the same thing for you, if you were swapping disks out then it seems that's what will do it. I had figured that you could just swap disks around, but obviously not... must be something on the board that ties it to a particular disk.

Thanks again to you both for taking the time to reply, hopefully this post also helps someone else when they hit the same problem in the future.

Cheers,
Troy
