After a spanned volume is extended, no portion of it can be deleted without deleting the entire spanned volume. Spanned volumes cannot be mirrored or striped and do not offer fault tolerance. If one of the disks containing a spanned volume fails, the entire volume fails.

So there's no benefit in using a spanned volume at all... it's like a RAID0 but worse.

And if I shrink the volume on the original and create a spanned volume from that, wouldn't that just make a second partition on the original that spans to the new drive, separate from the first partition on the original?

Hmm, not sure if I should use it.

Thanks for the help guys.
Well you are the one that asked. You didn't want another drive letter in Explorer. But you want to put another drive in. Yes if you shrink the volume to create unallocated space you will end up with another drive letter. But if you save all the data and use the WHOLE drive along with the new drive it will be only 1 drive letter.
