firewire drawing power
on my friend's laptop, whenever he has a FW device like an iPod, or if he has a cd in the drive, it uses his battery power like nobodys business, so, i'm wondering ig in desktops, if you have a FW device or a cd in there, even if you are not accessing it, does it use alot of CPU or power?

i think if your portable is running on batteries then iPod won't be charging when connected. (at least in 10.2) Your laptop has to be connected to power in order for iPod to start charging.
Again, maybe it's changed in Panther.
As for CPU usage, I would think it's extremely minimal, if any.

If it's a firewire device charging from the computer it's connected to, then yes, it will obviously use some power regardless of what it's connected to, desktop or laptop.

that's what i wanted to know
Firewire devices can use a significant amount of power, though typically this is only true of bus-powered devices, like the iPod.
