No, you didn't ;) In fact, I even think recent MacOS (or is it MacOS X ?)
may create pure HFS+ volumes without the wrapper.
The main reason for the wrapper was for machines running non-HFS+ capable
filesystem to display something (where are all my files gone ?) instead
of proposing you to format the disk, and for the system to be able to
boot from HFS+ since OldWorld ROMs didn't understand it. Basically, the
wrapper contains a slim-fast MacOS System file which contains the necessary
HFS+ support to mount the real volume and continue booting from that.
Ben.
