Hi, I have just built a HTPC and the Agility 4 128gb ssd I chose to be the boot drive is giving me grief. It shows up in bios (Asus P8Z77-M with latest bios) but does not show up in windows 8, not even in the windows install screen. I have updated the firmware on the drive via OCZ's update tool and the drive formats and is accessable on my desktop computer, another Asus MB baised on the Z77 chipset, running windows 7 ultimate. I have tried 3 different sata ports on the P6Z77-M, all with the same result. Any suggestions?
