I'm confused by where the "desktop" is. How many disks are there, and how many partitions? Output from "sudo fdisk -l; mount; df -m" would help. If you have two disks, made a single raid partition, and installed ubuntu to that, then your root partition is probably mounted from /dev/md0 already. If your root filesystem is somewhere else, and you want to use extra space on /dev/md0 for something, then it would have to be formatted with a filesystem and mounted somewhere.

When you say you can't write to md0, what command are you running, and what error message are you getting?
