I recently bought a new Hard Drive for my Inspiron 531, a Hitachi 1TB. I have set my SATA Controller to SATA 1+2 and when I boot up and hit F2 it shows the new drive. When I go into Control Panel/System/Device Manager/Disk Drives it shows both drives. The problem is that when I go into My Computer, it only shows the C Drive (the main drive), the D Drive (the backup portion of the original drive) and the two CD/DVD Drives I have installed. It does not show the new Hard Drive. How do I get my system to recognized the hard drive under "My Computer"?
