Just got a digital camcorder. Plugged in to the USB port of my Mac but it was not "recognized." When I go to disk utilities, you can find it as a removable disk. But, it is protected. I removed the protection on the camera but it still is not showing up as a hard drive on the Mac. The camcorder has a hard drive in it. It is supposed to show up as an external HD on the Mac. Why does it not? What should i do?
