If the card is intended for your digital camera then try to format it in the camera itself. DO NOT format it in the computer if it's meant for the camera. If it isn't intended to be used in a camera then you could possible attempt a format in the computer. These cards usually arrive ready formatted which makes me think there is a possile fault with the card itself. But try the format routine and see how you go. I know it's new but it is possible a small amount of grease or dirt could have accumulated on the gold connections. Rub these with a small piece of printing paper to clean them up (printer paper is very abrasive and makes a great electrical contact cleaner)
If you have no luck then a trip to where you bought it and see if you can get a replacement.
