When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board. Some drives may
also have an audio connector; one end of the audio cable attaches to the drive connector and the other end attaches to the system board.
Drive Interface Connectors
Serial ATA Connector
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.
When you connect an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When you disconnect an IDE cable, grasp the colored pull
tab and pull until the connector detaches.
When you connect and disconnect a serial ATA cable, hold the cable by the connector at each end.
Power Cable Connector
Hard Drive
1. If you are replacing a hard drive that contains data you want to keep, back up your files before you begin to remove the hard drive.
2. Follow the procedures in "Before You Begin."
Removing a Hard Drive
1. Disconnect the power and data cable from the drive and from the system board.
NOTE: The system board serial ATA connector may have an attached cover or shroud.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the 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.
