So I have a ordinary pc with a 500gb seagate hardrive in...and I have another seagate hardrive I want to put in (also 500gb) but do I need the sata power cable since it is not the main hardrive or can I only insert the Data cable for the harddrive since I didn't get any cables with my hardrive do I need need both cables, the Data and power cables or can only use the data cable ?
You always need a power cable as well. The power cables are part of your computer's power supply unit and are never being shipped with harddrives.
the cable is connected to your power supply - you don't get a separate cable with your hdd - usually those power cords have 2+ connectors so just see which one fits (one of them might already be connected to your dvd drive or w/e)
Hello You need to connect sata power cable and sata data cable both in order to make it work. One drive will be primary(from which OS will boot) and other will be secondary. Just connect both drive from motherboard using sata data cable in both ends also sata power cable. If not enough ports free in your smps then use a splitter cable to split the connection.

The drive needs both power and data. You'll need something like the cable in my source. Figure out where you're going to draw power from before you order a cable. The cable that I link to will connect into a 4-pin molex connector. It is a passthrough connector, which means that it has both a male and female end. If you have a 4-pin molex that is already in use, this splitter connector goes in the middle so that the molex still provides power to the original connector. I'm not sure if I'm explaining it well.
yea you need both, the data and the power cable. Power need to go to the hard drive via the power cable and the hard drive need to communicate with the motherboard via the data cable.
