I recently bought an HMC myself and the Transcend 16GB Class6 and PNY 16GB Class4 work fine, but when I purchased a 32GB Transcend it would not work with the camera at all it gave me a “check card” message and would not allow me to record or format the card…The card works fine in two other still cameras and on three computers, but no matter how much I format it, the HMC completely rejects it. Any ideas?
