| You Said=2ndly yes it is a IDE and it is on the primary as the master and i have set the jumper to cable which the Compaq website says to do. |
This is a little confusing, if you set the original drive jumpered as master you should set the new drive as slave and not CS.
Or, if you have the 80 wire ribbon you can set them both to CS. You also need SP2 installed to use the 250 GB drive.
