seems it is almost empty, probably hardly ever used. Doesn't seem like corrupted, u could not read from it in that case. |

Someone may have tried poking in it with it's production tool, and have re-written the controller Info? It happens in that cases.. |

How are you reading the data? Directly from the stick or with the chip removed in a programmer? Have you tried to rework the soldered connections to the memory chip/s? I would try that next. |
