"hdparm -C /dev/whatever" should tell you. Disks that are spinning show up as
active/idle, disks that are not should be standby or sleeping. Disks that
are USB give me a set of weird SCSI errors and "unknown", though, so YMMV on
this.

In general, you won't be able to spin down any disk that
contains / , /var , /usr , or /home unless nobody's logged in.
