I just got a Samsung 850 Evo SSD and I plan on cloning my old HDD drive that has my OS on it to my new SSD. So far I understand the cloning process using software seems fairly easy. However, most of my questions are for after the cloning process is complete. I've read that after the clone you just remove the old HDD and put the new SSD into the sata port that the HDD used to occupy, boot up the computer, and it should run fine. The thing for me is what if I don't want to use the same sata port? I want to use the 6gb sata port for the SSD. The other thing that concerns me is settings in the BIOS menu. Do I have to change it to AHCI mode? and if so, when should I? I've read people have changed to AHCI mode before a fresh OS install to an SSD drive but what about when cloning? I've tried to look for steps of the process but I couldn't find much for my particular situation. I just dont want to screw anything up. Any advice, answers or questions would be great.
