Firewire 400 and 800 together

I have 2 external HD firewire:
120Gb Firewire 400 and 500Gb Firewire 800.
They work fine EXCEPT when I connect both HD to my PB.
I have to use 1 at a time, not together.
Do I have to do something to use them togheter?
Its both LaCie HD

PB G4 17" 1.67/1x1Gb/100Gb Mac OS X (10.4.8)

Last time I needed to do this, I daisy chained one off the other, which worked fine. So one was connected to the PB and one was connected to the drive connected to the PB.

Thanks for the suggestion,

I tryed that to, but none of them mount on the desktop when I start my PB.

In the meantime I found the solution…
I restart and reset PRam and after that it works when I linked as you suggest.

Thanks

Ben

I tried once hooking a 400 drive into the 400 port, and an 800 drive into the 800 port, then transferring a big file between them. A 1.2 GB file finally stalled at about 10 hours. I then daisy chained the 400 into the 800, and the 800 to the PB, and that worked fine. I now frequently hook 4 of them, only 1 of which is 800, and as long as it is hooked thru the 800 to the PB, it works fine. If I unhook the 800, and plug the chain into the 400 port, that works fine. I don't have the right cables to go the other way, but that would slow down the 800. I can hook it in as 400 in the case of hooking it all up to my MacBookPro without FW800.
