I bought a K-5 last month and I've encountered the error "Memory card error" several times when turning on the camera. Just turning the camera on and off obviously doesn't help; however, ejecting and inserting the card again resolves the matter.
This is with a Sandisk 16 GB Extreme SDHC. I haven't found a specific way to reproduce the error. Just now I turned off the camera (the card was functioning correctly), popped out the card, put it in again, turned on the camera, and... error. Hm. Took it out and in again and it worked.
It's not a big problem but it's slightly unsettling. Not sure if it's the card or the camera. Any ideas?
