it may be a stupid question, but does it work?
i have two macs and one is connected to my external firewire disk. while both are running could i connect another mac to the second firewire port on my disk? i.e. can two macs see the same firewire disk? can they both read/write to it simultaneously?

you can try. the worst that could happen is your system would freeze.

yes and no. yes both Mac's will (should) be able to see and wright to the disk. no, if both machines attempt to control the device at the same time there will be some kind of error. After all the read/write head on the drive can only be in one place at a time.

Well, I can tell you that I can't use an XP and OS X machine with the same drive. Plug it into computer 1 and it "locks" it. The second computer doesn't even see it until I unplug the first computer. YMMV.

You can't keep the file system integrity together with 2 computers accessing one drive at once. Well you can with clusters, but they have specialised mechanisms to allow this.

I tried the same with an external DVD-RW. It has 2 firewire ports. So I thought to put 2 firewirecables in it and send two burn-signals from both machines ..and let one computer burn with TOAST and get a friendly "please wait till other computer is finished burning".
Idle hope. None of the macs sees the writer.
They sell USB-switches (use 1 usb-device on multiple macs) but this is not possible with firewire. It cannot make a loop. You can chain it though. That's why it has 2 ports.

File this under "please kids, don't try this at home".
If you really want expensive fireworks, try connecting 2 SCSI macs to the same drive. You will have created a "Terminator" of your own.
