Windows7 Create Striped volume

Question

I'm trying to raid0 a data partition on two disks in Windows7 Pro 64bit.

Both drives are identical, partition scheme is identical, I have converted them to dynamic disks.
But all the raid options in disk management are disabled.
Does Win7 Pro not support raid? Then why does it let you create dynamic disks?

Answer 1

It seems you have to click on the non-boot drive first and create striped volume on that, then add the first drive to the set.
