I’m on a MAC, and trying to find solutions has been a total pain in the freaking neck. At least I was able to copy all of my files off of it, and onto my HD as backup. I discover though the file info, that it is suddenly read-only, and I have no clue as to why or how it happened. Suddenly, out the stinking blue, I can’t copy anything to it, nor delete anything from it.
I’ve been using a Sandisk Cruzer USB stick for a few months now, no problems.
