Here I have simply initialised the disc, in other words written a new root directory and free space structure at the front of the disc using the existing settings. If I had formatted the disc, I would have lost over 1100MB of space in the process!

It's a bit sneaky although I appear to have got away with it!

The only concern is that the free space message at the end is incorrect, suggesting that the disc size is only about 715MB.
