Hi, I have an Asus K53sm laptop, which is not detecting 2 Crucial MX500 2 TB SSDs simultaneously. I have inserted one in the Primary slot & the other in a Caddy in place of the optical drive. One of them is my boot disks which work fine. But the other is not detected in windows at all. However it works perfectly in an external enclosure. I have tried to insert another HDD (Toshiba drive 1 TB) along with my primary SSD and it works fine. Can anyone help? is it a hardware limitation OR I need to enable some option in BIOS?
