any computer gurus here?

RAID 0 is "striped for performance", RAID 1 is mirrored, the only choices I have for this older controller card.

Instructions say to install drives (bare)
create array using fastbuild (auto) for performance (striped)
Then it says use need to FDISK and format array as if it were a single drive.
Then install new OS
I guess I missed the FORMAT step, will do that next
