Hello! I've purchase a 2nd HDD from newegg and it just came in the mail. I plugged it in correctly. It will not show up in My Computer. Now I looked up solutions and I have tried Disk Management and it will not come up. I found it in Device Manager because it installed the driver when I installed the HDD. I also found it in BIOS when I was looking at HDD boot thing and it displayed as #2. Im 90% sure the disk is spinning due to hearing it once it boots and it vibrates when on. I been having a bad week so far and I hope this one isn't DOA! Also It's a Hitachi HGST 500gb HDD.
