    HDDs Show in BIOS, But Do Not Show in Disk Management


    Hello,

    A newbie here that just completed a first-time new Win7 PC build. Successful installation of Win7 Pro on WD 600GB 10000 system drive. Went back and installed 4 additional HDD. (2) WD Caviar Black 1TB 7200 RPM and (2) WD Caviar 7200 500GB HDD from XP system that were used for storage.

    BIOS sees all HDDs, but are not viewable in Disk Management.

    System Specs:
    Antec Nine Hundred
    ASUS P6X58D-E MOBO
    Intel Core i7-980 3.33ghz
    24GB (3 x 4gb) Corsair XMS3 1600mhz RAM
    PNY Quadro 4000 2GB VC
    Corsair 850TX 850W PSU
    1 WD 600GB SATA HDD for OS
    2X WD 500gb SATA HDs (previously used on WinXP system for storage)
    2X WD 1T SATA HDs
    1 Pioneer Blue Ray Burner SATA BDR

    BIOS SATA Order:
    SATA1=WD 600GB
    SATA2=WD 1T
    SATA3=WD 1T
    SATA4=WD 500GB (previously used as storage on XP system)
    SATA5= Pioneer BDR
    SATA6= WD 500GB (previously used as storage on XP system)

    SATA configuration is enhanced. BIOS is 0701. Marvel 9128 Controller [IDE Mode] PCI/PnP is set to [NO] which was the default setting. The grey SATA1-6G headers are not in use.

    Device Manager lists all drives.
    However, only three are visible in Disk Management. Missing (1) WD 500GB (previously used on WinXP system) and (1) new WD 1T.

    What am I missing here?

    Thanks in advance.

    I agree, are you saying they do not show in windows explorer or in disk management. They are two entirely different things.

    If they haven't been "initialized", then they won't show up in Windows Explorer. Press Windows + R and put in diskmgmt.msc to check there.

    It would also work better if your SATA setup runs in AHCI mode rather than IDE mode.

    If you're trying to set up a RAID, then you might just have to refer to the motherboard operations manual.
