Makerbuino - Faulty SD Card

The SD adapter and SD card supplied with the Makerbuino are faulty. We noticed this when checking the inventory - removing the SD card from the adapter was a struggle, and it still sticks whenever it is replaced.

Tried reading it on my PC - nothing.

I have another (6GB SD card and adapter) - how do I set it up to work with the Makerbuino?

Hmmm… wiggling the SD card in the Makerbuino seemed to get it working.

But why can’t my PC read it? It works fine with the aforementioned 6GB SD card…
