I guess most all USB 2 PC Cards have that external power plug since, as you say, it just can't get enough power for some external devices from the PCMCIA interface.

Is that only used if your USB 2 PC card doesn't have that external power option? No reason for both PC card and the HDD case to be powered I'd guess.
