There has to be a numbered SATA port on the motherboard into which the SATA cable from the hard drive was plugged into. Make a note of this SATA port number.
Get into the BIOS and activate this SATA port by number. Unused ports are turned OFF at the factory. Whenever a device (HDD, DVD drive) is added, the SATA port into which the cable is plugged into must be activated (ON).
