Matthew Holland 5 years ago Ok so I just purchased my shiny new Panasonic AG-HMC 150 and a 32GB Transcend SDHC card to shoot on. The only problem is, when I stick in the card the camera asks me to "check card." And when I go into the card functions on the menu, it says "incompatable" and is also unable to format the card. I have tested this same card on two computers and a Cannon Still camera. All have no problems reading and writing and formatting the card...the HMC is still being stubborn...However it will recognize and use a crappy class 2 4GB card I had, but that doesn't help me if I want to record high quality, or for very long....Can anyone tell me why everything else can recognize and use my card but the HMC won't?
