That is not my experience. I have a Lacie enclosure with a 7200 RPM Hitachi 2.5" laptop drive. The drive will NOT spin up correctly when plugged into a USB port on my T43p. It works fine when powered by a provided Lacie power wall wart (quite small) and then plugged into either of the two USB ports on my T43p. It does work OK when powered through a 6-pin Firewire connection with an iMac but does not work correctly with only the USB connections on an iMac. The Lacie enclosure supports 400 MB firewire (standard 6-pin socket) and USB. A different Lacie enclosure with a slow 1.8" 60 GB disk works fine on the T43p USB without an external supply. It is rated to draw no more than 0.5 Amp total. I think that the spec for power from a standard USB/2 port is 0.5 Amp (I have read that but I've not read the actual spec). Spin up current draw according to the spec on the 7200 RPM Hitachi is 1 amp ...
