    I have a new pc (2 months old) with Windows XP and 3 500GB discs in RAID-5
    (total of 950GByte available). I'm using the on-board Intel ICH8R chip with
    Intel drivers.
    Now I tried to install Vista x64 on a seperate partition of 100GByte (on the

    I thought this new shiny Vista DVD would have all the drivers needed for the
    latest and finest hardware. So I just started the PC from DVD. Vista install
    starts and after a few clicks shows the 'available volumes'. The existing
    RAID-5 array is mentioned as '950GByte Unallocated space'. PANIC, my Windows
    XP is in the first 850GByte, it's not unallocated.
    There is a button to install a driver (from floppy !!!), but I dont have
    that driver so I decide to reboot in WinXP.

    BIG PANIC, the pc doesnt reboot. The RAID-5 array is corrupt. It seems Vista
    has written something to one of the disc (only one, LESS PANIC). The
    BIOS/WinXP system needs some manual help and then starts rebuilding the
    RAID-5 array. A 24-hour mission.

    Why did Vista write something to this disc? It almost destroyed my WinXP

    I dont trust it anymore, no Vista for me anymore until someone has
    thoroughly tested this.

    Oh yes, the RC2 I also tried, this did not even boot, some driver error. But
    it did not mess up the raid array.

    Any suggestions?

    Did you ever find a solution to this problem? I'm experiencing the same
    issue with my RAID 5 array. I eventually installed Vista on a separate
    non-RAID disk.

    Interestingly, I have experienced the same problem with another product that
    uses Windows PE, the installer used by Vista. I wonder if it may be a
    Problem with Windows PE.
