Hi kford,
It was on the Intel controller and I have also tried placing it on (from SATA port 1 to 6) and its not recognized once I shut down the PC completely. I need to unplug the Power cord and leave it for about half and hour and reconnect, only will BIOS recognizes it.
No I have not reported it to ASUS. The thing is my Samsung EVO 840 120 GB SSD always shows up.
Guess if a new firmware for the Intel 530 SSD will fix this hopefully.
