Converting RAID 5 to RAID 10

I have a PowerEdge 600 SC running Win2000 Server with a CERC ATA100/4 Channel RAID controller. Presently I have three 40GB drives in a RAID 5 configuration and one 40GB drive as a hot spare.

 

Is there a way (without starting from scratch) to convert this to a RAID 10 configuation? According to the controller info, it can run a RAID 10 configuration, but I don't see a way to reconstruct it from an existing RAID 5 setup. I am hoping to speed up database access by converting to RAID 10.

 

It seems like it should be possible, but I just haven't figured out how.

 

Thanks!
