[DM-MUG] Electrical Q ref external harddrives

[CW Smith]

Victoria:

Tell us more about the laptop that won't power this drive: is it new  
enough to have USB 2.0? or is it an older iBook/PowerBook with USB 1.1?

USB 2.0 (on your Mac Pro and MacBook) carries more current than USB  
1.1 and shouldn't require additional power. More info please?

Peace,
CW
