1 power cable
2 power input connector
Connecting and Disconnecting Drive Cables
Most 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 IDE cable—SATA cables do not use a colored stripe) 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.
When removing an IDE data cable, grasp the colored pull-tab and pull until the connector detaches. When connecting and
disconnecting a SATA data cable, hold the cable by the black connector at each end.
NOTICE:
When you connect an IDE data 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.
Hard Drive
CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide
.
CAUTION:
To guard against electrical shock, always unplug your computer from the electrical outlet before
removing the computer cover.
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.
Removing a 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. Check the documentation for the drive to verify that it is configured for your computer.
4. Disconnect the power and data cables from the drive.
