That's a surprise I use a couple of external portable harddrives that
only require one port.
Oh yeah I am using a PC so maybe that is why.

My first gen MBP has a free USB port on the right side and on the

only the port on the right can power my USB hard drive that I use for
backups and my iTunes collection. I use the port on the left side to
support my IPhone and my iTouch.
USB, being a PC technology picked up by Apple during its dark days, is
technically a mess. One can have no reasonable expectation about what
can and can't be successfully powered. I carry a portable drive with
me that works fine with FireWire. To connect it using USB I have to
carry an extra cable. First I have to plug in one cord into the drives
power socket and plug that into one USB port. Then I plug in a second
USB cord to carry data and supply additional power. The drive won't
work unless it is getting power simultaneously from two separate USB
connections. I see that as pretty shameful engineering.
