So, in prep for going to my parents', I put the jump drive in so I can reformat it and use it when I go over there with Opportunity. And guess what? Now , after I've reconstructed all of Friday's work, now it's working just fine. Like nothing was ever wrong with it. And I said, "Shrink -- I wanna kill....." Murphy's Law continues to defecate in my trousers, it seems. Sigh.
