I suspect it depends on the controller. The main problem is that most
firewire or USB drive controllers assume just one computer at a time. This
means they don't build in the capability of taking requests from more than
one interface and queuing up requests from one machine when the drive is
busy doing something for another machine. Lots of potential to step on each
other as well. What happens if both machine see a spot on the drive is
empty so they both start writing to it and updating the directory with
different filenames as being the owner of that spot. NAS devices already
assume multiple concurrent systems and users and so they have all these
checks in place. For example, if you were about to write a 10MB file to a
NAS, that space would be allocated first, then written so that some other
user on another system couldn't come in and overwrite your file's
allocation.
That said, there are firewire devices which are designed to be connected
to multiple computers, like this one:
http://www.sancube.com/
but today with Gb ethernet on most computers, it's just as fast or faster
to access a shared drive that way. So the ideal to me would be to hook the
drive up to your Mac via Firewire 800 (fastest interface) and the
fileshare it out to a Gb Ethernet connection to your PC. Even 100Mb
Ethernet is going to give you 10MB/s. I did a test on GbEthernet and I
think it pegged at 35Mb/s which was the max throughput my drive could do.

Hi Alex,
That's not necessarily true. The general term for that is a NAS (network
attached storage), and more devices than the airport networking hardware
from Apple support that type of usage. It ranges from a single hard
drive
NAS device (like the Western Digital MyBook World Edition) to very
expensive
redundant storage like the Drobo with a device called DroboShare (both
together are about $4-700 depending on which model you buy, BEFORE hard
drives!). And if you have a computer to spare, you can set up your
computer
to share that hard drive over the network to others, but that computer
would
have to be on every time you'd want to use it on another.
Also, Apple does sell a single device called Time Capsule that combines
the
Airport networking hardware with a hard drive, but in my opinion it's
sort
of overpriced and inconvenient if the hard drive ever fails.
cheers,
jane

Hi,
You could actually share it over the network by attaching it via USB
2.0 to an Airport express, Airport extreeme or one of the computers on
the network. If using the third option, it is possible to use
firewire. I recommend using the airport method. It worked really well
for me.
Thanks for listening,
Alex,
