Yep.

So get SpeedStor V5.x, which includes a driver for a thing called a
"SPAN-DOS" disk, which is a multiple-volume fixed disk driver.

Allows up to 512MB on one partition, and spanning two drives.  Rather neat,
but it does have one drawback:
	
	If either drive dies, all contents of the "Spanned" partition are gone.

Be careful, and keep good backups.  If you really need this kind of space
then it will work, and do the job quite well.

Disclaimer: We sell the product, as well as use it in-house.
