I have a new G1W and I am using a ADATA 32gb class 10 card in it. The card was formatted in the camera using GUI Format and it sort of works......... The red record light blinks approximately 10 to 15 times then disappears only to start blinking again after 10 seconds. The files on the card are short in length and not constantly 3 minutes in length or size. Not sure what is going on. Should I go out and buy a class 6 card?
