[2008R2 Web Edition] I removed a volume instead removing a mirror... How to cancel or recover data ?

Hello,

One of my disk or a windows mirrior was broken and i wanted to remove the mirror. No backup, it was a backup disk...

I have just done a big  mistake, I clicked in Remove Volume intead of remove mirror on a Windows 2008 R2 Web Edition.

Is there a way to rebuild the volume as it was ?

Thanks 

Laurent
