I downloaded sdtool but I don't have the required devices in /dev to use it. In the readme it says not to use /dev/sd* but to use /dev/mmcblk*. It seems my card reader doesn't connect in a way for those to be created. Would have been nice just to see what it does tho. I still wouldn't trust it of course but being curious . . . . By the way, the card is a Sandisk which has a fairly good reputation. It is possible that it failed in the best way it could. On the positive side, it did fail in a way that the files could be recovered. That's always a good thing. It's certainly better than failing with no way to get the files. Dale :-) :-)
