Dunno about "JBOD", but RocketRAID cards also have "legacy" mode,
where you DO NOT EVER configure your drive using the onboard BIOS.

Drives treated in that fashion are "portable" to other controllers.
But beware the (posted earlier) nastiness about the onboard BIOS
overwriting a sector 1GB from the end of the drive.

To be save, don't use the last 2GB of space (or read the earlier post
and figure out the exact limit based on the sector calculation formula).
