    WOOOOHA . . .

    Stop me when I go wrong:

    You have three physical disks - let's call them 0, 1, 2.

    You do not have a hardware RAID controller - or if you do, you aren't allowed to change the config.

    The Win2K Disk Administrator sees three disks 0, 1, 2.

    AFAIK at this point the only reason to "stripe" is for performance.

    Oracle will multiplex Control and RedoLog files, but you only get full value of doing that if that each member of the "group" goes to a different physical disk.***

    If you have logical drives (C: D: & E: ) striped across the physical disks, then most files will have blocks on all three disks and a disk failure will wreck them all.
