    After a fiasco with two firewire hard disks (the courier company lost them), I have to purchase an external firewire HD. Once the insurance company refunds my money (which can take up to 90 days), I still want to get the other 2 disks I ordered.

    Is there a limit on how many firewire drives I can daisy chain? I was thinking on having all 3 hard drives daisy-chained to my iMac.

    63 is the limit of daisy-chained FireWire devices.

    So there should be no problem with having three drives (A, B and C), and having A connected to B, which is connected to C, which in turn is connected to my mac? All three drives would be properly ventilated.

    I don't believe there would be, though I have never done it. You won't blow anything up by trying.

    There wont be any problem, and firewire is actually a good way to do it.

    I have four firewire units daisy-chained, the first three being optical drives, the last a hard drive. The only hassle is that if you're using the first unit in the chain, Nos 2, 3, and 4 must be switched on, or No 2, in which case 3 & 4 must be switched on ... and so on, even though they may not be in use. In that case I pull the f/w plug from the chain and put it directly into the Mac. Have your most-used unit last in the chain.

    For the reason outlined above, some people prefer a f/w hub.

    By last in the chain you mean connected directly to the mac, right? I don't think I'll have much problem, since I plan on having all three drives on at the same time.

    I've thought about buying a Firewire 800 hub, are there any you recommend?

    Yes, that's right.

    I can't honestly recommend because I've not used one, but see here http://search1.superwarehouse.com/search?w=Firewire Hub for numerous options. Recognised brand names are Belkin, LaCie; Cables To Go has had good feedback. Be aware that, whilst still available, some models are discontinued.

    Bit of bump to an old thread, but I was wondering if people have had problems chaining fw800 devices on Early 2009 Mac Mini.

    For a while i've had 2 firewire (Freecom Datatank) devices working fine, added a 3rd device (Freecom Quattro) and the Mini keeps crashing (BSOD telling me to restart) when transfering large amount of data (using rsync). Could I be overloading the fw800 port?

    I've also tried the 2 Datatanks on FW800 and the Quattro on USB and it dies as well. It's looking as if I might be sending the Quattro back, but I like to check first to see if it's not just me.

    I successfully transferred 400gb earlier and it was fine, getting annoying at the moment!


    (just a thought, I renamed my old drive Storage_old (from Storage) and named the new volume Storage - wondering if that's the issue? As the earlier backup was from the volume called Raid - Renamed the new volume to Store - will wait and see what happens)
