Hey ALE, wonder what's favorite or highly recommended these days wrt USB-bootable PC diagnostic/repair toolkits. Keeping on-topic, best I can tell, what I've seen (e.g. gparted) is Linux-based. Guess that would stand to reason - should be able to at least "see" all hardware & it's immune to the (ahem) "sicknesses" of (ahem) other OSes. Thanks, -Ken
