No, all the drives are single drives (no RAID) and attached to one Intel SATA controller,
using individual connectors (drive C: is one of them, BTW).  Drive S: is a multi-purpose
card reader, which is actually a USB-interfaced removable device (so it's different from
other drives).

> fsutil volume list

C:\Windows\system32>fsutil volume list
list is an invalid parameter.
---- VOLUME Commands Supported ----

dismount        Dismount a volume
diskfree        Query the free space of a volume
querycluster    Query which file is using a particular cluster

But I ran this instead:

DISKPART> list volume
