If I'm tracking correctly, you have your OS installed on
another drive, you've added your Raid 0 array, and then
formatted and partitioned in through the Computer
Management / Disk Management snap in? Go back into Disk
Management and make sure you included the entire space
when you created a Primary/Extended partition after the
drive was recognized. I've got ahead of myself by having
the partitions sizes I want and clicked through
the "create partition" menu too fast and only reserved
part of the drive for use.
You are right that Windows will "see" the array and treat
it no differently than a single drive as long as you've
set it up in the bios and resulting raid management
screen shown in the POST). BTW I have the same identical
Raptors set up in a Raid 0 array with a 2GB FAT16
partition and then the remaining space split in half for
a dual boot with XP Pro SP2 and Server 2003 on the
remaining partitions. When you do go to placing this
array as your boot drive, please ensure you've made a
floppy with the raid drivers for the F6 prompt when
reinstalling your OS.
