My Windows 7 Release Candidate is about to expire, so I'm going to do a clean install of a retail version. I have two volumes, on four physical drives, as follows:

Disk 0: Spanned Volume (D:)
Disk 1: Primary Partition, Boot/Windows Install (C:)
Disk 2: Spanned Volume (D:)
Disk 3: Spanned Volume (D:)

If I install Windows to a formatted drive 1, will it still recognize the spanned volume in Disks 0, 2, and 3? The spanned volume is not redundant in any way, so the volume is 1.5TB consisting of three 500GB disks.

I don't have the space to do an external backup, and I thought it was impossible to convert a spanned volume back to a basic volume.
