    I don't know if this has been answered before but is there a way of getting OSX to cut all firewire connections when it goes to sleep? Reason being is i have a soundcard and lacie drive on firewire ports and neither switch off when mac goes to sleep. The lacie is the more irritating factor because it keeps the disk spinning i.e. unwanted noise when i myself go to sleep... There may be some issues in this that i'm not aware of e.g. hard drive mounting issues but if anyone knows a good fix please post it.

    If you don't want the drive powered when you sleep, eject and unplug it before sleeping the Mac.

    My external firewire drives turn off when I put my mac to sleep.:confused:

    Mine stops spinning, even when turned on, after a stretch of not being used. The lights on it are quite bright, though, so if I want the lights off, I just eject and unplug it. That's the only way to shut off the power, since it still draws power from the Firewire port, even if the MBP is powered off, as long as it's still plugged in.

    The LaCie ones don't spin down unless disconnected or the mac is switched off.

    It just seems like such a hassle having to switch the drive off everytime. I need to get another drive soon too so i'll end up switching off every drive just cos the damn things don't spin down. I'm looking for a better way out really.

    This is probably vendor specific.

    My Wester Digital "MyBook" will automatically sleep when I turn off or sleep the connected Mac. And start again when the mac comes back on. Even works as a boot drive this way.

    And I did not have to install the drivers they give you for Mac OS X, either.

    This is so that you can charge your Firewire-enabled iPod while your computer sleeps. It might also be required in the Firewire spec, but I dunno about that. No way around it; sorry.
