Win7 HP 64-bit Disk Management options?

[VirtualLarry]

Is there some reason it offers spanning, and striping, but no mirroring?

Does it give you the option for mirror in the menu? if so then it need free space(no partition) to actually create the mirror.

If there is no option to do the mirror, then artificial limitation for HP

Yes. They want to make more money from people who want such features.

You need Pro to do RAID 1, and Server to do RAID 5.
