Good RAID array "unknown", "not initialized" after Windows 7 crash

  1. Hello all,
    I'm suffering froma troubling problem with a Windows 7 system.
    This system has a boot HDD (C:) and data storage RAID5 array (D:). The system locked up hard requiring a power down to get Windows operational gain.

    The sytem is fine now, except the ~3 TB RAID5 array is not seen by W7. The W7 disk managment snap-in reports that the 2793.97 GB "drive" exists, but the status is "Unknown" and "not initialized". Needless to say, the drve was online and contained LOTS of data before the crash. Due to it's size, the drive was GPT.

    I ran a synchronize on the RAID 5 array and that finished w/o error, so I assume the actuall array is fine.

    Any recommendations for what utllity/diagnostic/etc. to try next?

    Further info: The RAID 5 is a creation of the AMD SB750 "southbridge", which uses tech licensed by Promise Technology.
