If you've seen my post then you'll know that no memory card is safe not even Micro SD adapters although the Micro SD card inside would be unaffected.
I feared as much... But at least yours lasted for 2 years. Mine is bend after a mere 4-5 months. I think I might try the suggestion of the link explaining how to 'repair' the sd card slot, adding what I hope is sufficient support for preventing the sd cards to bend.
I also took a look at the adafruit adapter (http://www.adafruit.com/products/966
), which is thicker and therefore probably stronger which would hopefully make it last longer, but they don't sell it anywhere near here (Belgium) which means I'd have to pay $25 to get a $6 sd card adapter...
