There's a 2 gig internal and a 16 gig external. Nothing has happened with the 16 gig, ever. The install-tools-ad is what I am running. When I ran it the first time (on each 2 gig card) it gave an error some time after that "starting filesystem clone" message appears 3 times. This error suggested my ejecting the card due to some inability to write or something. Re-inserting the card and re-running the program resulted in it running all the way through. Sorry if all this was not clear.
