Why not name names?
What make/model card and size?
I have a Konica/Minolta Dimage Z5 and I have just bought a new SD card for it. The problem is that the camera will not recognise the card; It just says "System Error" and switches itself off. Is there anything I can do to get my camera to work with the card? By the way, I tried this card in a PC and it works perfectly well.
