So, some of you may know, my firewire ports have packed up and left. So, i was considering buying a firewire 800/usb2 pci card.

The card has 3 usb2 and 3 firewire 800 ports

My question is, i know usb2 is backwards compatible, but is firewire 800 compatible with 400? as i have a camera and a external HDD that i need to use.

Nope, FireWire 800 is a whole new plug. So you can't plug FireWire 400 devices into a FireWire 800 port.

However, you can buy cables that adapt Firewire 800 to 400! Firewire 800 is just a kind of "dual channel" Firewire 400, ie: uses twice the number of connections.

And a firewire 800->400 adapter works wonders...

Speaking of firewire... anyone know any companies that sell 2-4 bay cases... If I could get hold of some decent looking external scsi cases, it might pay for me to buy some firewire -> ide bridges from the USA and install into said case so I can have 2-4 IDE devices

Someone on ebay is selling some, but to buy it complete from USA would cost too much. I'd be better off sourcing a case local and then buying just the bridges from the USA and making my own.

Yeah what everyone else said..

Also.. some people were saying to me a while back that if you use the FW800 & 400 at same time you reduce them both to 400..- well on my powerbook anyway... any truth to that?

i cant believe im up this early...

I would be really surprised if that were true Estoyloco. Considering Firewire 800 really only serves one purpose at the moment (external raid arrays for HD editing, one market Apple's very serious about) I don't think that's likely

Yes and no... daisy chaining devices is possible with firewire.. and thus if you daisy chain a fw400 device on the bus (subsequent devices after that can't be fw800). I think thats what they mean...

I can't imagine the fw800 device thats first on the chain being slowed to fw400... but I know logically the devices after the fw400 would only be as fast as it.

Hope that makes sense..

Cases with 2 or more bays are still hellishly expensive, try Zytech, epowermac for them, or indeed, grab an old SCSI case and get some adaptors, at equally huge expense from Firewire Depot.
