The Nokia 2GB mini-SD card that came with my Navicore Navigation Kit no longer works. It happened with the previous firmware in the external slot. It worked for about 1 week and then while using the Navicore software the app locked up and I had to kill the process. Since then the card is totally dead, it is not picked up as being inserted on any system that I have tested it on. I did nothing to the card, so it would of been formated as FAT by Nokia.

I now have 2 Transcend 4GB 150x cards, and I am a little worried that they will be destroyed as well.

Does the problem only occur with FAT, not FAT32 or Linux, file systems?
