4.If you are replacing the drive you removed with another drive, remove the guiderails and screws from the drive and use them to install the other drive as described in “Installing a Drive in a Horizontal Bay” on page
5.Wrap the drive in its original packing materials and store it in a safe place.
6.If you removed your computer’s only hard disk drive, disconnect the hard disk drive ribbon cable from the system board and store it as well.
If you removed one hard disk drive and are leaving another one in the computer, you need to set the jumpers on the remaining drive to indicate that you now have only one hard disk drive. See the documentation that came with the drive for the correct jumper settings.
