heard that some external HD's don't work on macbook pro because they
run via USB and no power supply is needed. (via mains plug ) and the USB is power is not enough to use the HD...is this true for the following HD's and the normal macbook?

i haven't had a problem with running 2.5" drives up to 80Gb with one usb connection on my regular macbook (not pro).

i think this may have been an issue with some older ibooks and such, but i haven't heard of any issues lately. additionally, most newer 2.5" ext drives and drive enclosures seem to come with the double usb cables to tap two ports if necessary.

I have an iBook and my WD 80GB USB powered HDD runs just fine. Should be fine on a Macbook.

The problems with power only tend to happen if the root hub is overloaded, e.g. if you run two such drives of a single USB interface. For normal use, and if you plug it directly into the machine rather than via a hub of any kind, you should only need a single USB connection.
