Thanks for the kind words.
You make a couple of good points.
Nothing wrong with a live-usb.
I went with live-CDs because the OP posted:
"I'll check out LiveCD as it sounds like what I probably need" when replying to a comment by syg00. That and the fact that none of my ageing motherboards have a bios that will boot to usb means I have no recent experience of Linux on a usb stick (not that that invalidates your point). As to SD card readers, I used to use (and still do sometimes) a usb stick that takes SD cards. If the computer has usb ports and a cd drive it should be usable. A couple of those usb card readers cost very little and would allow for disk to disk cloning. Even if the OP buys an external usb cd drive to boot from, the costs would be much less than the $450 the milling machine people want for a new SD card. Now I come to think of it I do have an HP netbook that will boot to usb (forgot about that). It was a while ago now but back then my success rate with live-usb was less than half that of when booting from an external usb CD drive. Things are probably better now.
Best regards dogphlap.
