A8N-SLI Premium loses SATA drive

    About once or twice a month, starting about 4 months after I built my
    rig, my A8N-SLI Premium will freeze during Windows launch. On
    rebooting, the POST pauses a long time at "detecting drives," then
    finally finds only the SATA drive I use for backups, NOT my Raptor.
    Naturally, I then see a "no system disk" error. I would open the case
    and reseat the power and SATA cables of the Raptor, although nothing
    ever seemed loose. The Raptor (C: drive) would then be detected OK
    every time.
    Yesterday, instead of opening the case, I simply switched the PSU off
    for 30 seconds and then switched it back on. The Raptor was instantly
    recognized. So it turns out that all it takes to get the drive back
    is completely powering down the motherboard. I believe that my "fix"
    of reseating cables was a red herring.

    Is the mobo faulty or is there another possibility that's not obvious
    to me? Could a faulty BIOS chip do this?

    I've the same problem. With this configuration:
    NVIDIA SATA 1 = Western Digital RAPTOR (74gb)
    NVIDIA SATA 3 = Western Digital 2000JD (200gb)

    After some freezes i've lost mi fireware port.

    You might want to try a better power supply.

    Really? I have an Antec TPII 500W. It suppose that it's possible
    that it's faulty, but it's plenty powerful enough for this rig, and
    its voltages are always spot on for all rails, well within it's design
    tolerance, on all the monitors I have.
