No you don't need to jumper anything on the drive! SATA is a backwards compatible interface and so it will work anyway.
Is the port it is connected to set to IDE or AHCI mode?
Do you have Native iDE enabled in the BIOS?
Are your other hard drives SATA or PATA?
Yeah both of us said this about the jumpers but we're running out of ideas!
Both are SATA, one is a WD Caviar Blue, other is a Hitachi both 320gb
I tried both IDE and AHCI mode also, no joy
I remember seeing that native IDE was also enabled. What would be the effect of disabling this? treading lightly here as i dont want to be unable to use my two currently functioning drives.
Thanks again
