It's stored in the disk label.

What you are seeing is actually the partition name, not the disk name.

For example, this is the first internal drive on my system, which has 
two partitions:
BenNevis and Loch.

/dev/disk0

    9:              Apple_HFS BenNevis           27.9 GB   disk0s9
   10:              Apple_HFS Loch               27.9 GB   disk0s10

As I recall, you can't change the name without re-partitioning under OS 
X.
