If you go into Disk Utility, you'll see your devices laid out like :
Disk model identification
Drive Volume name (partition1)
Drive Volume Name (Partition2)
etc (as I recall, it's been a long time sine I used drives with
multiple partitions, there's little reason to do so.)
on the left hand side.
Actions done while the top line is selected apply to the entire drive
device, actions done while a volume is selected apply only to that
volume.
