[QUOTE="Bluegrass, post: 677270, member: 32459"] Not all external hard drives will run straight from USB ports without a separate PSU providing the power to the drive. MacBook Pro's do seem to have low power USB outlets (mine won't even charge my Blackberry). There has been some discussion on this forum so would suggest you do a search. The other solution is to buy a powered USB hub to connect your hard drives to. [/QUOTE]
