I've recently installed a 128 MB SD memory card in my em 500. Worked great for about a week, but yesterday it quit. The device doesn't seem to recognise the memory, and asks if I want to format it. If I say "yes" it gives me an error (code 21).

I had installed Casio's update 1.04 - I understand this is supposed to fix the SD card issue. I did a hard reset and restore from backup - hoping this would fix it - it didn't.

I've heard of problems with SD memory in the em 500. Anyone have any experience or advice?
