Default Project Mix I/O and Firewire 800 external drive

hi guys
I am having issues with my external hard drive, everytime that I open prootols ( Project Mix I/O ) with a firewire 800 drive my computer freezes and I have to press the power botton down in order to restart it. When I use it whith other applications I never have a problem like this one, seems like a power related problem or something like that, since its shutting down my mac.

I am using a Mac Pro Two 2.66GHz Dual - Core Intel Xeon
External HD Western Digital 320GB My Book Pro Edition connected via firewire 800
Project Mix I/O
Protools M-Audio 7.3.1 cs4
Mac OSX 10.4.10 Combo Update

If anyone can help me with this problem I really appreciate.

thank you

I wish I had better news, but I pulled this off the WD website;
"Western Digital now uses Oxford 922 and Initio 1430 bridge chips in our external hard drives that implement FireWire."

According to Digi, they have only qualified Oxford 912 and 924 chipsets. So... I'm not sure what that says other than if you contact digi, they may tell you the same thing. I'm also wondering whether mixing a FW400 device (Project Mix I/O) and FW800 device is causing some grief, but I can't say for sure.

I have an early 2007 iMac 24" with a FW800 and FW400 port and when I plugged my FW400 drive into the FW800 port, I experienced exactly the same symptom. To remedy this I switched devices (PM I/O on the FW800 with a 6/9 pin cable and FW400 drive into the FW400 port). Your configuration is different, however I thought that situation may shed some light.

Hey Marcio. I don't think the 922 chipset will be a big deal. I did a lot of research on this before I bought my external hard drive. You have to run everything at the same speed (FW400). Otherwise it causes issues on the bus.

I'm running projectmix FW400 output to a FW800 port. Then I'm running my HD FW400 output into FW400 port. Never had any problems.

Yes I wasn't sure whether the chipset would be an issue, however if you call digi, it might be "flagged" as one. As for the FW400 devices I suppose that's what I was clumsily trying to say.

You'll probably need to get a FireWire expansion card:

Problems in combination with FW800 hard drives.

marcioguitar, I am using the same exact computer as you, except I use a Lacie FireWire 800 hard drive, and I had the same exact problem with my machine crashing when plugging in both the FireWire 800 drive and the ProjectMix to the Mac's internal firewire ports.

But instead of reading the M-Audio post that TechKnowledgy posted, I went out first and bought a PCIe FireWire 400 card (assuming the problem was something to do with the port sharing, even when using my PC with a firewire 400 drive, the ProjectMix and firewire drive liked to both have their own ports, not to share the internal port of the machine). I've been plugging the ProejctMix into this card, and the Lacie 800 firewire drive into my Mac's port.

Things "kind of" work... (you can reference my posting on my ProjectMix not working correctly on my new Mac here), and as you can see, the M-Audio article recommends you do the exactly OPPOSITE of what I did... get a PCIe FireWire 800 card, and plug the drive into that, while plugging the ProjetMix into the Mac's internal firewire port.

So I was wondering if you bought a PCIe FireWire 800 card, and if you did, how is your setup working now?

Thanks,
Mike

hi Mike
well, I did not try yet, I am still using my firewire 400 instead of using the firewire 800 drive.
I am wondering since PT 10.4.10 its not qualified yet maybe Digidesign will come up with some update or something like that, but as you can see nothing happened yet!
I will let you know once I get the card and install!
thanks

Hi guys, I had the same problems a few months ago. I am running a 2.2 MacBook Pro with two of the Western Digital 800 Drives.

I believe your main problems will come from mixing fw 400 and 800 bus speeds. I ended up routing mine this way.

Firewire from the MacBook Pro to the 400 input of the first drive then 800 to the second then 400 to the Project I/O. Because the first drive is connected at 400 the 800 connection is now also at 400 to the second drive and 400 to the project i/o.

I would also suggest chaining the drive or drives and put the project i/o at the end of the chain. I am running 32 plus tracks with numerous plugins with no problems. There is plenty of bandwidth on the 400 wire to cover the needs of most users.

Have an OWC FW800 drive but looks like I don't have the 800 option (unless I install a dedicated FW card) if I'm using a FW400 interface (ProjectMix) as I experienced the pop/click/drop-out syndrome when I had the drive on FW800 and the ProjectMix on a FW400.

The pops seemed to be in sync with the sample rate turning red and green (lock opening and closing) in the ProjectMix/M-Audio FW Control Panel (Hardware tab).

Hooked up the drive to FW400 up front and the ProjectMix to the FW400 at the back of the Mac Pro. So far so good...

I recently heard that somebody worked around this issue by turning on the hard drive first, and the M-Audio device last. Apparently this allowed them to use an M-Audio FW device & a FW800 HD connected to the computers built in ports (FW HD TO FW800 port & M-Audio to FW400 port) without problems. It may be worth a shot. I only have a MacBook and can't run FW800, but would be interested to know if this worked for anybody else.
