cooperbill78 these are the jumper settings for a Seagate Barracuda ATA harddrive,
http://www.seagate.com/images/support/en/us/u5_family_1.gifAs you can see the jumper should be on Pins 7 and 8.
Make sure the harddrive is plugged into the END of the flat ribbon data cable.
Pin 1 goes toward the power connection.
Some flat ribbon data cable's connectors have a Locating Lug on one side. A square protrusion, or two ribs.
This lug lines up with a cutout in the circuit board on the back of the harddrive.
If no Locating Lug is present, and/or no Locating Notch in the harddrive, make sure Pin 1 is towards the power connection on the harddrive.
On one side of the flat ribbon data cable is a faint red stripe. (Sometimes hard to see)
This red stripe is on the same side as Pin 1.
When installing the flat ribbon data cable, ensure that the red stripe on the cable, faces the power connection on the harddrive.
