Memory card is broken. Insert a new memory card.
Memory card type error Insert a supported memory card.
The camera cannot read or write data on the
memory card.
Turn the power off and on again, or taking out and inserting the memory
card several times.

It might be due to a bad contact of the placed memorycard.

1. Pull the memorycard out and in the camera several times and retry.
2. If not OK, format the card in the camera. If that does not work, format it in the computer.
3. Try another memorycard and recheck.
