    Yes, as you suspect this could be a fault on the mobo. But, as it is intermittent it could just be a bad connection or a faulty SATA cable. About the only suggestion I can offer is to try a new SATA cable.

    When the drive dissapears have a look to see if it is still recognised in the Bios.

    If you're running Windows 7 and have the drive in "AHCI" mode, (SATA), if the drive doesn't spin up fully fast enough, (within 10 seconds), then it will disappear. There is a windows update for this. First see this thread: Then, check out this hot fix from M$:

    If this is a system drive, the machine crashes. If this is a storage drive, it will just disappear. This happens with SATA drives a small as 640GB, no matter what the KB article says. Keep in mind the problem mostly occurs when resuming from standby.

    I hope we're talking about the same issue, as this is an easy fix

    As a shot in the dark you could see if there are any more recent drivers for the motherboard and check for an update to your Bios.

    Event Viewer : Warning Detected on device \Device\Harddisk0\DR8 during a paging operation

    OK, I would run the checkdisk utility and see what it finds, if it is just bad blocks causing the problem the disc check should cure it but it will indicate that the drive is failing and more bad blocks may well occur.

    Don't know your OS so:

    Windows 7 and Vista.
    Windows XP

    If this problem is repeating for just that one drive then you should replace it. Running the chkdsk /r command will stop the bad blocks from being used but it is likely more bad blocks will occur as the drive deteriorates, it's not something that is going to get better.

    How old are the drives? If they get a lot of use they could all have bad blocks but on reflection that would be quite a coincidence. Is your power supply powerful enough as that could cause a problem. My final thought would be to test the drives performance in another PC, if it works OK in another PC then chances are that your original thought of a faulty motherboard may well be correct, especially when considering that the drive also disappears from the Bios.

    the drive in question is under 2 months old, but all of them have had this issue, 1000w psu ultra x3, and yeah i think it is the mobo had this issue since i got it, so i guess since ive spent about 500$ in HDDs mine as well spent 150$ and get the crosshair V lol
