Appreciate all the advice, thanks to speedygonzal for your posts and trying out all that, telnet & using PuTTY is all new to me and I haven't quite got my head round it yet, so while it might not have been a success it saved me a lot of trial & error.
Filezilla is also new to me but I've been trying to learn and I'm going to try and follow what you ask above. I'll set it to record something tonight and report back.

1999gtv I've disabled timeshift and today whilst trying to sort out my epg I've had no issues, prior to this I was getting as low as 32% without making any recordings.
I'm on 5.0.0002 and appear to only have 1 folder on my hdd (media/hdd) I had 2 yesterday with a bookmark? Has turning timeshift off got rid of this? As I've said I'm in uncharted waters here and really not got a clue what I'm on about.
