    HI guys,

    I'm working on a computer with a RAID setup. It is 2 hard drives 500gb each showing up as 1tb in windows. Both drives show up in the bios but all of a sudden when trying ot start the computer I get a "Operating system is missing" error.

    I'm trying to run a chkdsk form a win 7 64 bit disk and telling it to run on H; (system drive) but it says 'cannot open volume for direct access'.

    The other drive, C: is just a recovery drive built into dell computer systems.

    I tried using a boot cd and running mbrfix to no avail. Any ideas?

    You need to provide a LOT more information; the information you provided is somewhat confused.

    Two 500GB drives, showing up as one TB. Does this mean the drives are striped?

    Where, exactly, is the drive you are calling C: and claiming is the recovery disk?

    How, exactly, is each drive formatted and partitioned?

    Is this hardware RAID or software RAID? If hardware, whose controller? If software, which?

    Sorry, yes it is Raid 0 striping.
    Drive C: is a partition that dell sets up by default for reinstalling the factory system. In this case it is drive c:
    drive H: is the near 1TB (2 striped 500gig drives) partition that contains the OS and files.

    Drive H: shows up as raw when externally mounted by itself using a USB dock. Not sure about the raid specifics, but it is the dell aurora alx.

    When using a boot cd, I can navigate files in the H: drive fine for backup purposes but would like to get it booting again .It started with blue and black screens (i never saw them myself).

    So sorry for wasting your time guys, I should've known this. I reset bios and it changed from RAID to AHCI. Just had to change it back to RAID.
