So, basically I was trying to install a second HDD for my rig, but my SATA I cord wasn't long enough, so I bought longer SATA III. My motherboard is rather old and has 2 SATA I connectors, so main HDD runs with SATA I cable. The problem is, I've plugged everything in and HDD is just not detected. What's the problem? I heard all SATAs are compatible? Please help.
