Can You Daisy Chain Firewire 400 and 800 Mixed?

Russ,
Yes, it is possible. I have a drive that works on FW800, FW400, or USB2. Connected to the second FW800 port on that, I have an adaptor cable, a FW400 cable to a FW400 drive, and another FW400 drive connected to that . All 3 drives are on the desktop of my PowerBook. When I read your post, I had the only first drive connected to the iBook with USB2.

The only problem I've run into was trying to copy a 200G drive on FW800 to a 250G drive on the FW400 port on the PowerBook. Working overnight, it managed to copy ONE Gigabyte! I hooked them up as they are now, and copied the whole shebang in about 45 minutes

I picked up an empty drive case, 800/400/USB2 combo from OWC and a 250G Maxtor drive at CompUSA for about $100 less than I could get a 250 FW800 drive anyplace. http://www.macsales.com

Separating The Tortoise And The Hare
Not all FireWire devices are created equal; some devices support faster transfer rates than others. For example, DV camcorders deliver data at the slower 100Mb/s and 200Mb/s rates, while hard drives typically deliver data at the 400Mb/s rates. When the devices are daisy-chained (connected to each other and sharing a single port), the devices may be reduced to the transfer rate of the slowest device. With a separate FireWire PCI card, you can isolate the slow devices to one port, while dedicating another port to your high-speed devices.
