Hi everyone I know there is a million threads on this kind of thing already but I've looked through so many and haven't found a fix to my problem. My current build is FX-8350 and GTX 980 Ti on a Asrock 970 Pro3 R2.0 motherboard with 8GB ram. Currently my system is running off of a 500gb HDD, I was given an old OCZ Trion 100 120GB SSD from a friend but my system for some reason couldn't detect, it wouldn't show in BIOS, disk management or device manager. I initially thought the drive was faulty so I went and bought a Kingston A400 120GB SSD but this wouldn't detect anywhere either. I've tried both SSD's on every SATA port and got nothing but the HDD works on all the ports, I've swapped over the SATA cables and they work with the HDD but nothing with the SSD, I've also updated my BIOS and all drivers but still nothing. The closest I've got to any sign of detection was when I enabled AMD AHCI BIOS ROM and then rebooted I got a screen that showed the hdd and ssd but said SMART error for the SSD. I should also note that I put the SSD into my laptop and it was detected fine. The only fix i can really think of now is just to replace the motherboard but all the ports etc work fine with the HDD just not with the SSD's. PC's are never simple :lol:
