4 drive to 2 in a Raid 0 array?

[defcon88]

Hello, I have 4x 250GB Sata hard drives set up in a Raid 0 array using my Asus P5NE-SLI Motherboard's raid controller, and Im trying to figure out a way to go from a four drive raid 0 array to a two drive raid 0 array without losing data, and without using an external hard drive over 30GB, because thats all i have...any ideas?

any ideas?

alot of blank DVD's, seriously. without having an external harddrive(s) or without being networked to a server or other computer where you could backup your files, your kind of SOL. there is no way you can decrease the amount of disks in a RAID 0 array without losing ALL your data.
