    Intel G33 motherboard's AHCI not detecting hard disks


    What could cause it?

    PC is a HP m9088hk. The SATA has 3 modes: IDE, AHCI and RAID.

    Now only IDE mode detected the 250G hard disk! The SATA DVD burner was
    not affected, working both in IDE and AHCI modes. The SATA cable seemed
    to be fine as well.

    Well, that's a new one.

    Other people have seen such things. It's possible there is a correspondence
    between "flaky disk" and "AHCI not detected", in which case you'd want
    to put the controller back in IDE mode and run a hard drive diagnostic.
    And see if the drive is healthy or not. While not mentioned in this
    thread, you also have the option of "Clearing CMOS" (with computer unplugged).
    If all the ports responded uniformly, then I'd blame the hard drive.
    Otherwise, I'd suspect a corrupt CMOS value, not detected
    by the simple minded checksum used to protect those bytes.

    http://www.sevenforums.com/hardware-...ed-bios-2.html

    The evidence almost hints to me, that the BIOS code may be
    doing more disk checking when in AHCI mode, than when in IDE
    mode. If SMART is enabled at BIOS level, it might even be
    possible for the BIOS to issue "SMART short test" or similar
    command, if they wanted. I think there are SMART diagnostic
    commands in the ATA/ATAPI command set, which would not normally
    be used except by Seatools or the like. You don't really want
    to be using a built-in diagnostic, if it causes an unacceptable
    delay to the user (user doesn't know what is happening while
    a disk test is running). So if the BIOS was doing that, and
    not just reading the SMART stats, the test duration would
    have to be very short.

    The 250G hard disk is a Seagate. Maybe I should swap in other brands
    and/or newer generation ones.

    Let me disable SMART and try again! Tomorrow... :)

    I should also try removing all PCI/PCIe adapters.

    BTW, if you could remember, I had complained about a motherboard losing
    BIOS settings all of a sudden in this newsgroup.

    It's that motherboard! :)

    Bad thing. Got a BIOSTAR that did that, except, rather than
    occasions, every time it booted up. Nice board in all respects as
    advertised/spec'd out, severely discounted for new from a company with
    something of a long-standing reputation, dating back with computer
    building hobby community, and now recently out of business. Only
    thing lacking was it was too good to be true. I did, however, make a
    point of filing a credit-card dispute against how they handled return
    shipping costs;- stupidly while doing it, as it's petty pinching
    stuff, that my credit card absorbs as a courtesy to good-standing
    customers, under a certain monetary limit precluding the retailer's
    involvement.

    American customer service is a thing of the past for many as
    consolidation in the global market probably excludes hiring at that
    level of profit, considering anyone worth the salary and particularly
    competent (or trustworthy as I saw it).

    I wouldn't want a dead BIOS on a new MB from a premier seller, NewEgg,
    say, and would raise hell if they sold me one for new pricing and
    refused to absorb my shipping for something blatantly wrong. People
    whine a lot, for a lack of technicality, if not outright abusive, so
    storefronts are harder and careful about returns.

    Run it for a 24/7 computer, never turned off while it lasts;- they all
    more or less exhibit degradation over time, quirks, if not becoming
    downright mean. Had a MB once that ruined, burnt out drives and power
    supplies. BIOS is way cool, comparatively;- bad capacitors dragging
    down other components into oblivion, enough of that will make one hate
    anything but reasonable MSI/Gigabyte solid-state capacitors.

    I've mixed feelings about Intel. They can tend to be modest,
    no-frills and somewhat outdated for a broader scope of available
    features, (deep sale/discounted), if often placed at prices well above
    the norm where more contemporarily deserving of notice.

    That HP Pavilion m9088hk PC was using an Asus motherboard. I think we
    cannot blame Intel chipsets for BIOS problems. :)

    Must have misread you saying it was an Intel board, straight across.
    With an Intel processor, it'll be licensed for Intel chipset support,
    in part;- nope, don't believe offhand I've ever run into a MB that
    booted up to a BIOS screen Intel designed and implimented. Not sure,
    why either, AWARD or the likes of a few others have an effective
    corner on BIOS chips variously implmented on MB brands.

    It's natural to assume companies like HP & Dell would use motherboards
    from companies other than Intel. :)

    Sometimes, I thought there was a naughty ghost inside that motherboard.
    It's too weird....

    Not really. Between a dual core x4200 AMD and the MB's chipsets,
    including video support chip on my multimedia computer, the level of
    processing going on and subsequent heat. . .'weirdness,' knock on
    wood, I suspect, is just a matter of time, now, after going on three
    years heavy usage.

    All things considered, the price of such a computer, as well as
    rebuilding a replacement, though, is very reasonable. So is being
    accustomed to a five years computer life expectancy, except I've never
    had a computer, such as it is, capable of heavy loads and degrees of
    program processing I'm now used to in a manner of course for
    multimedia.

    I was/am still being puzzled by the mysterious loss of CMOS data in that
    motherboard. I had replaced the power supply with a Antec 430D as well
    as the CR2032 battery, didn't help. Note that it didn't happen
    frequently, just a few times.

    I do/did assume that the user didn't play tricks on me.

    That would be hard to track down, even in a
    fully equipped lab. Especially as it could be
    a hardware issue or a software issue.

    That is strange, and not something you want to see stay around. It'll
    turn it into a computer you never want turn off (you'll get tired soon
    of setting up the CMOS every time it boots).

    I may have a little of that weirdness accompanying a 2-SATA header on
    my AMD Gigabyte -- though more to do with these large terabyte drives
    (and an extra PCI SATA controller slotted). Next board is going to
    have 6 or 4, at a minimum, SATA headers.

    Just lost my NEC 40" display after about 5 years use, in between that
    last post to you and now. Took a 32" SYNTAX LCD display across the
    room and now I'm back on a 19" Samsung. :(

    Talk about weird - that SYNTAX is almost twice as old as the NEC.
    Almost jumped on a new 32" LG LED, but it was HDMI only and I want a
    VGA connector included. Take a little getting used if I stay at 32"
    on the multimedia, but I want something bigger for here. Might be
    time to think IPS, not just that, but a 26" display I think I'd like
    (the 32" was a hair too big for close-up computing).
