Connecting the drive involves two distinct cables: the SATA data cable and the power cable. The SATA data cable, usually supplied with the motherboard or the drive, connects the hard drive to the motherboard. These connectors are L-shaped and can only be inserted one way, making them user-friendly. One end plugs into the port on the back of the hard drive, and the other connects to a SATA port on the motherboard. Next, the power cable must be attached. This comes from the power supply unit (PSU). The user must locate a free SATA power connector—which is wider than the data cable—and plug it firmly into the drive. A loose power cable is a common cause of a drive not being recognized, so ensuring a snug fit is vital.
