Your evidence does not necessitate that conclusion. You did not have an example of successfully copying multiple GBs successfully and all the failures you cited were for such large transfers. So your experience proves that either you are right or I am right. When I have 10GBs or more to move I have given up on USB. Such transfers are quick and easy with FW. This is using many different brands and over many years of trying. I try to never use FW with Apple's G5 Pro towers because I think they have a defect that occasionally fries my drive interface. To avoid the expense I use USB whenever I can with these Macs. I would love to use USB for large transfers, but I can't. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
