I've been trying to install and partition my Samsung 840 Pro SSD but I've been having some difficulty. I've set the SATA ports to AHCI, I've connected all the necessary cables, and I can even see the drive in my BIOS boot selector. The only problem is that Windows cannot locate the SSD in disk management and so I am unable to partition it or even transfer any files to it. Am I missing something? I'll gladly post screenshots wherever asked.
