I downloaded sdtool but I don't have the required devices in /dev to use |
| 46 |
it. In the readme it says not to use /dev/sd* but to use /dev/mmcblk*. |
| 47 |
It seems my card reader doesn't connect in a way for those to be |
| 48 |
created. Would have been nice just to see what it does tho. I still |
| 49 |
wouldn't trust it of course but being curious . . . . |

By the way, the card is a Sandisk which has a fairly good reputation. |
| 52 |
It is possible that it failed in the best way it could. On the positive |
| 53 |
side, it did fail in a way that the files could be recovered. That's |
| 54 |
always a good thing. It's certainly better than failing with no way to |
| 55 |
get the files. |
