I have a 12" PB with a FW400 port and a Lacie external HDD with both FW400 and FW800.
The FW400 port on my Lacie got fried by my 'Winblows' box! Leaving me with only FW800 on the HDD. I know the drive is still fine as I've tested on a friends 17" PB.
Would I be able to buy a new Dual connecting HDD, plug the new HDD into my PB via the FW400 port and then Daisychain the new and old drives together through the FW800 ports??
Or would this cause some conflict issues?
Many Thanks

You could always get an adaptor or cable that goes from 9-pin (FW 800) to 6-pin (FW 400). Something like this: Sonnet | FireWire 800 to 400 Adapter, which would plug into the back of your HDD.

Thanks for that!
That seams like it will do the job perfectly for me in the mean time
Would you happen to know if what I wanted to do above is possible?
At some point I’m going to get a second HDD and thought that if I set it up in the way mentioned above I might get better data transfer rates between the 2 drives??

Yep, you can daisy chain FW drives together with both 800 and 400 as you wanted to. However, since the data has to be passed through the bus in your computer, I don't think the data rates will be noticable different no matter whether they are daisychained or not.

I'm thinking that the fastest you'll get is 400 if the traffic has to go through a FW400 device.
How did the Windows box damage the port? ALL firewire cards are supposed to protect both the power and data lines so neither the external device nor the computer's interface are endangered by the other. That's weird.

I think you're thinking of USB. Quite a few people have dead/fried FW ports.

Thanks for the info chaps much appreciated.
Thanks for that link mduell about the dead FW bus problem (which I’d not thought of) I'll have to do some investigating.
I've also got a iPod that will no longer mount which I assumed the windows box had also blow, but it is now looking like that iPod could have killed the FW Bus on my PC and my MAC

Maybe that was just more optomistic than reality...
