Hello. I'm attempting to format my new 160gb WD hdd which I bought to install into my MB to increase space. I put the hdd into the external and connected it to the mb. I opened disk utility and clicked on erase to mac OS extended journaled. It started to format for about 5 seconds and then just stopped. I repeated this step several times. I even checked for software updates and updated just in case that was the problem but it still didn't work. Was there anything else I was supposed to do? The hdd is fully inserted into the external and all of the lights are on. Could my hdd be dead? And if so how can I tell? Can someone help me and tell me if I did something wrong?
