RAID

I have a Gigabyte board with an nForce 430 chipset that supports RAID. I was hoping to use it to create a simple RAID1 mirror using two hard drives to protect my previous MP3 collection. The system in question is an updated Kubuntu Gutsy box.

Before we start, this is the first time I am playing with RAID and the information below might very well be wrong. Please feel free to correct me :)
