My HTPC has an ASUS H77 motherboard which has 6 sata ports. 4 are sata 2 (blue) and 2 are sata 3 (gray). I have a leftover MSATA SSD 32GB which I have it connected with an msata => sata adapter for my OS (as I dont need anything else except the OS and XBMC this is large enough) also I have a 3 drives x 1TB. The issue is whenever I connected the SSD on the sata3 ports is not being detected in bios if its on AHCI (if I put it IDE it being detected) Any other drive it is detected on the sata 3 ports. Unfortunately I don't have another msata adapter to test just so I can remove it from the possible issues. Any ideas?
