I have a Dell Inspiron 531 running Vista Home 32bit. It has a WD 250 GB HD master. I bought a new 2TB Hitachi Deskstar to add as a slave. They are both SATA. I have four SATA ports on the mobo. SATA 0 is for my WD HDD. SATA 1 is for my DVD drive. I plug up the new HDD to SATA 2 or 3 and the BIOS doesn't recognize it.
I unplugged the WD HDD from SATA 0, plug in the new HDD into SATA 0 and the BIOS recognizes. It seems as though anything plugged into SATA 2 or 3 is not being recognized in the BIOS.
I have tried the new SATA drive with and without a jumper on the back.
Can anyone tell me why my BIOS won't recognize anything being plugged in to SATA 2 or 3?
