    Yes. Just repartition the drives to avoid the final 2GB of each drive,
    and then you'll be safe.

    The RocketRaid BIOS that I examined here a couple of years ago,
    liked to write "metadata" over top of whatever was in certain sectors
    near the end of the drive. EVEN FOR NON-RAID DRIVES.

    I think it was the last even (power-of-two) multiple of 1GB or something,
    so if you leave the final 2GB untouched, you're guaranteed to avoid it.

    Thus the recommendation.
