I'm going to assume you have all your files in the My Documents folder. You can format and set the new drive to another drive leter then go "Start"->Right Click on My Documents then change the path to the new driver letter. Of cores you would have to copy all of the "My Documents" folder over to the new drive.

I will tell you that using a Raid-0 is a Very, Very, Bad idea. Spaning a OS over two drives is just seting your self up for disaster.

All these options are good but if you were going to make a RAID-0 I would recomand buying 2 more dirves and make it a RAID-5 with backup.
