I just bought a new SATA hard drive. I am currently running 2 PATA. Well, when I installed the SATA drive, I checked the bios, and the device appears. When the computer boots up, I check explorer and my computer, and the new hard drive does not show up. I then check the device manager, and it appears there. I also checked the device status, and it said the drive was working properly. Why can't I access my new hard drive? Do I need to set up a Raid configuration?
