I hope this conversation about piracy is not aimed at me!!
Anyway, back to the original discussion for a moment ;-), I have now started the process of transferring everything onto a nice, big, fast internal disk and in 17 hours (!) when the copying has finished I will know if it has worked as hoped. Fingers crossed.
One of the benefits of that copying (which I did not know until a week ago!) is that the copying process will 'unfragment' the copied data and store it as efficiently as possible.
Silver lining eh'?
Dave.
