Also, for a PC use USB 2.0 for drives and firewire for video. No need for you to rediscover why this is so.
if i have a piece of hardware that accepts a 6 pin firewire cable and go down to a 4pin firewire cable into a labtop am i losing any transfer speed? the next question is that if i have a external hard drive with a 9pin socket and i have to go down to 4 or 6 pin do i lose any transfer speed, if so is there anything made that i could use the firewire800 hard drive and buy an adaptor or something in which my computer only has a 4pin socket, ?? any suggestions or links
