Hi Racerdan, a few years back a similar thing happened to me, like many people I used to take my SD card out regularly to download the photos. One occasion I removed the car and one of the gold connectors was dislodged and rendered the card useless, since that day I very rarely take the card out and always use the USB wire. Please be careful when inserting/removing your cards, although I must say your card seemed to have a manufacturing fault.
Cheers,
John.
Except that others will say "don't use the USB cable...repeated use makes the camera's socket loose and it will fail..." (and I've seen it happen)
