I had a bit of a panic today.  Just as I was gettng to the end of taking my pictures a message came on the screen saying there was a problem with the card and I should switch to another.  The camera has 2 slots so I duly switched to the other (after confirming that I could no longer view any of the images I had taken!!).

Fast forward 6 hour and the images downloaded to the Laptop o.k. so a big sigh of relief.  The card also now seems to  be fine but I'm not sure I should risk it again.  (Its a Transcend 32Gb card).
