re: #104 Higgs Boson’s Mate
If all else fails you can try Wise Data Recovery. It’s freeware. I use GetDataBack and it works really well, but it costs $79.
Going to try it in another computer tomorrow before starting data recovery efforts. I’ve seen flashdrives act wonky before and then straighten out.
Also will check whether I still have the photos on the other computer as well. Would suck to lose over a Gig of photos.
