Pin 11 can be used for activity indication and/or staggered spin-up. If pulled down at the connector (as it is on most cable-style SATA power connectors), the drive spins up as soon as power is applied. Not just this but also it’s the standard connector for all SATA-based optical drives or hard drives. (3.3 V Power, Pre-charge prior to SATA 3.3) The SATA 15-pin power cable is the standard peripheral power connector in PCs. Another free program I use is called CleanUp that you can download from. The same physical connections are used on 3.5-inch and 2.5-inch notebook hard disks. For SATA drives, attach the data connector with the exposed metal facing up. One pin from each of the three voltages is also used for hotplugging. This is because the small pins cannot supply sufficient current for some devices. The seemingly large number of pins are used to supply three different voltages - 3.3 V, 5 V, and 12 V.Įach voltage is supplied by three pins ganged together (and 5 pins for ground). The SATA standard specifies a power connector sharply differing from those used by PATA drives and many other computer components. At startup, run the CMOS Setup program and configure your BIOS so your drive is detected. If the drive you installed is not detected, restart the computer. ![]() ![]() ![]() At startup, the computer will display all the devices detected on the system. Molex 67581-0000 used for cable connector and Molex 67582-0000 used for terminals connector. Replace the system cover, reconnect the power cord, and power on the system.
