I assume that you are going to be using Linux software RAID.
You can convert to RAID-1 (mirror) without destroying your system.
You can't convert to RAID-0 (stripe) without destroying your system.
However, it looks from your post as though you want to convert to RAID-1.
Two points:
1. Check out the Software-RAID-HOWTO - if you don't have it installed,
it's at http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html - section 4.14
will help you plan the conversion.
2. It sounds like your setup will have your mirror on the same IDE
channel as your primary. That may be risky: there's a possibility that a
disk failure will take out the whole channel.
Hope this helps
