external HDD connection question

Just a simple question I hope!

I have a new WD My Book Studio Edition that seems to have every connection under the sun. I planned to use the Firewire 800 connection to my iMac, but might need to use the drive under Windows on occassion. Is it possible to use the drive with its Firewire 800 connection on the Mac and then, when needed, unplugging it and then utilizing a USB 2.0 connection on my PC?

I could always just use USB 2.0 across the board on the Mac and PC, but I was led to believe that Firewire 800 would be faster if available so why not. I just don't want to run into any issues down the road.

Also, if I use it with Fusion I don't think I could use Firewire with that, only USB 2.0. Perhaps USB 2.0 is the better option overall?

Thanks for any advice!

Re Firewire-USB, I have been able to use either/or with my Seagate external drive, but not connected simultaneously. USB is more cross-platform friendly I've found. Check too that you're using the correct FW 400 or 800 ports. FW is definitely faster.

Thanks for the reply, hughvane. I had suspected as much but it's good to get confirmation.
