Can you partition a RAID1 volume?

[techserv]

This is my first time setting up a RAID volume. I have a hard drive that is not part of the RAID array that Windows is installed on. Then I have 2 other drives that I am using for data storage that are successfully setup as a RAID1 volume. They are brand new unformatted drives.

Can I simply use Windows disk management to create different partitions on my RAID volume?

 

[HAVOC]

If you have the two drives set in a RAID 1 Array, you can not partition them like you would a single drive. One disk is already the Primary Partition and the Other is the Mirror Partition. (2) Identical Partitions on seperate disks.

This is the essence of RAID 1. Fault Tolerance.
If you lose your Primary Partition, you can still boot and retain data from your Mirrored partition.

I could be wrong, but I doubt it.
