My Macbook pro Firewire port is intermittent and it's driving me nuts. It works when I first plug things in and then stops. I'm eventually going to buy a new computer but I'd really like to wait for a few months if there's a fix for this. It's actually been going on for a long time but appears to be getting worse.
Examples: I plug in an external firewire drive for Time Machine. It usually completes the backup but later will drop the drive, and if the system goes to sleep, it will wake up and cycle endlessly looking for the drive (which I eventually have to unplug).
I monitor through an Apogee Duet. In Ableton Live, it'll run for awhile, but then if I stop a song in the middle and start playing again, it will get all glitchy. I can unplug the Duet, plug it back in, then reset my audio preferences and it will work fine again for a few minutes. Also, Ableton playback starts glitching at lower processor levels than if I use the built-in audio.
Things I've tried:
switching out the cable on the Duet
never plugging more than one device at a time into the firewire port.
2007 MBP, 17", C2D 2.4, OSX 10.6.6. Any suggestions? Anyone have a similar experience? Is there any kind of definitive test you can do on a firewire port?
but maybe its this underpowered thing. i currently drive duet and external lacie disc only with bus-power ...
must check with an powered hub.
Yes: IOGear makes decent FW hubs. Or if your external drive is AC powered many have two ports so you can loop through to your interface. This works fine on LaCie drives. You might need a FW400 to 800 cable.
I think the FW bus from the laptop tops out at 15 watts. Or rather that used to be the case.
