Rated. / 5. Based on customer reviews
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the cable) goes to the pin-1 end of the
connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or card.
Hard Drive
1. If you are replacing a hard drive that contains data you want to keep, back up your files before you begin this procedure.
2. Shut down the computer through the Start menu.
3. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, turn them off now.
4. Disconnect any telephone or telecommunication lines from the computer.
5. Disconnect your computer and all attached devices from electrical outlets, and then press the power button to ground the system board.
6. If you have installed a padlock through the padlock ring on the back panel, remove the padlock.
7. Open the computer cover.

Interface cable
NOTICE: When you connect an interface cable, do not place the colored stripe away from pin 1 of the connector. Reversing the cable prevents the drive
from operating and could damage the controller, the drive, or both.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the System Information Guide.
NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
