CF Card failure - a bit different

Just got a new Extreme 32 San Disk.  Camera (G15 Canon) recognizes card.  Shot video and stills and iphoto doesn’t recognize the thing.  It recognizes my old 2 gb Kingston just fine but not this thing.  Insert the card in reader, plug it into usb, zip, nothing, nada.  Luckily, what I shot were tests but I did format the card with the same result.
