Self-built system using GA-P67X-UD3-B3 MB. I connected the DVD Drive to SATA3-0 port and the HD to SATA3_1 port. All ok. I wanted to add another HD, so I connected the new HD to SATA2_2 port. Win7 does not see the new HD, because I did not tell the BIOS that there was a second HD. I can't tell which switch to flip in the BIOS to let the system know there is a 2nd HD. Any idea?
