I wanted to replace system drive in my HP z420, however it is not recognized after installing it into AHCI ports (first 2 ones, 6Gb/s). New drive is ssd Crucial MX200, and it is working in SCU ports, but only at 3Gb/s. Any idea what's wrong? In AHCI ports it is not even discoverable in bios.
Try changing to AHCI+RAID. Do not worry too much as to what shows up in the bios since it is pretty primitive.
