I just destroyed my RAID array. Help.

[BP-Revo]

On my desktop, I have 4, 160gb Western Digital 7200RPM drives.

Two are configured into a Stripe array (Raid 0), and this is where my windows is loaded as well as all my games.

The remaining two drives are configured into a Mirrored array (Raid 1), and this has all my important stuff (obviously). My brother also somehow set it so all the "my documents" and user related stuff is saved on this drive.

However, while trying to eject a USB flash drive, I accidentally clicked one of my hard drives (damn SATA and it's hot-swap-ability). I always wondered what would happen and managed to go 2 and a half years without figuring it out. Go figure. Anyway, I force shut-off my computer right away hoping nothing would take and it would reboot like normal, but now my mirrored array is listed as degraded in my raid status monitor and during the self-test in the Bios on boot. I'm damn lucky it wasn't the striped array...

So, I have two questions:

First, is there anyway to restore the array without having to wipe BOTH drives clean? Like just have the computer erase one drive and copy everything to it to restore the array?

Second, if there is no way to achieve the above, will having my "documents and settings" folder gone for a brief period cause any major issues? I'm backing my stuff up onto an external hard drive as we speak.

This is the last time I "safely" eject my USB drives. They are getting yanked out for now on...
