not really an issue, just an enquiry
I have spent some time "tuning" my setup to work they way I want it
if the SD card have dies, it'll take a while to get back to my preferred setup
so I thought best plan is to clone the card
what technology did the clever lads/lasses at OctoPi use to create their card image?
I tried WinDiskImager (I think that's the name)
it seemed to make an image slightly bigger than the original SD card!
