Just a side note, typing the command "blkid" in terminal will list the block
devices (drives/partitions with block readable memory) by UUID and
corresponding /dev/partition if you would like to set up your /etc/fstab
manually. My understanding is that the UUID is used for more complex
systems with many drives and/or partitions. Under varying conditions, the
partitions could be given different /dev/partition designations by the OS.
Using the UUID in /etc/fstab ensures the correct partitions are mounted in
the proper location regardless of what label the OS has given the partition.
