I have two disks that I'd like to partially combine into a striped volume (RAID0). Disk 1 contains the primary partition that boots into Windows 7 Professional, disk 2 is currently not used. On disk 1, I have 20 GB of unallocated space, and disk 2 has roughly 110 GB of unallocated space.
My understanding is that I should be able to create a RAID0 volume using the 20GB of unallocated space on disk 1, and 20 GB of the unallocated space on disk 2.
Unfortunately, the Windows disk management tool only allows me to create a "New Simple Volume" on the unallocated space of disk 1, whereas on disk 2 I have the whole range of options at my disposal.
Why is that?
(I've attached a screenshot that's actually two screenshots merged together, showing both menus. I apologize for the Dutch language, but it should be fairly obvious what the available options represent.)
