Ok, I just clicked on the link, and if that's what happened to you, yes, you did have a hardware-based RAID. That's not what I am referring to above. Which may still work, anyway.

If you want to check in advance, just go to disk manager and upgrade your current drive to dynamic. Than right click on it and if you see a grayed "Add Mirror" option, you can create a mirror and all the system is waiting to enable that option is a second hard drive with enough empty space.
