I would like to use Spanned Volumes in Windows 7 to present a number of disks (or iSCSI LUNs) as a single volume. I like to maintain flexibility in my setups however.

Is it possible to remove a disk from a spanned volume in the future?

I can find documentation about shrinking volumes but nothing about later removing one from a set.

I hadn't used a spanned volume in some time, but from what I recall, the isn't a way to unspan a volume. Also, if you want to access the space of the drive/lun from within the C drive, depending on what you want to do, using mount points or junction points may do what you need. – Scott McClenning Feb 3 '12 at 2:11
I was going to use it for storing hd video, just a convenience method basically. I'll post the definitive answer to this, and possibly my alternative solution once I get my setup rolling. – Jacob Groundwater Feb 3 '12 at 3:51

You cannot remove a disk from a spanned volume in the future without deleting the volume itself.

That being said, just because Microsoft doesn't officially support such an operation doesn't mean it isn't possible.

Can you expand or link to details on how such an operation would be done? – Jacob Groundwater Feb 4 '12 at 5:59
I would think it would be technically possible on Windows, but not a simple task. There are products/file systems that I believe can do this, like Drobo's BeyondRAID – Keltari Dec 3 '13 at 4:49
