Fire Wire 800 connections

Am thinking about getting an external hard drive that uses Fire Wire 800 connection. Than realized there is only 1 800 port on this G5. So if I wanted to use another 800 port, it doesn't exist. Not to worry say some, 800 devices can be chained. Not to worry say others, there are 800 hubs just like USB has hubs.
Are any of these truth? What are the facts?

I understand what you are saying. On the main-line computers you hook many devices to a selector channel BUT only one device at a time can perform I/O; on a multi-plexor channel all devices can function at a higher speed than on a selector BUT still not up to their maximum. I would be reluctant to chain a device that would be operating at the same time as another device in the chain.
If chaining is possible, you would need in AND out ports, shades of the SCSI, wouldn't you. I've seen several small (160-250GB) but only one showed me a picture and it appeared to have 1 each USB, 400, and 800 therefore, no way to chain. The others gave me no reason to think they had "out" ports.

Have you tried any of these soundcards designed for 2.0?
The 3.0 port is categorically designed to be comoatible with all 2.0 devices. The port itself will adapt to the usage parameters of the device.
But if you really want to downgrade, then simply plug any 2.0 hub into a MBA 3.0 port. The ports on the hub will be 2.0.

Fire Wire 800 VS eSATA interfaces

Hello,
I am looking for a phat hard drive to use with my system.
The things that I am pondering; Fire Wire transfer speed as compared to eSATA transfer speed. Is it advisable to step up to a drive that has the eSATA option, or is Fire Wire 800 sufficient? Perhaps a raid array is the way to go?
If eSATA is the stuff, can anybody steer me in the direction of a vendor for an Express Card.
Thanks.

For the formats you work in using FCE FW800 is sufficient.

Fire wire 800 not working on IMAC

My Fire wire port on my IMAC 24 inch is not working now. I have tried switching cables, etc. This started when I had to have the hard drive replaced. The drives do work if connected by USB or FW 400.

Have you reset your SMC and PRAM? If that doesn't get your FW800 port going, run the Apple Hardware Test to see if it spots any hardware problem.

Fire wire 800 and the 24" imac

I'm strongly considering purchasing a 24" iMac. I see that a lot of people are having problems using their 800 port with external hard drives. I was wondering if anyone out there has had any success using it? The main reason that i'm buying the 24" instead of a smaller one is the 800 port. What do you guys thing...hold off until they fix it?

Tom,
Have you verified that using both the FW 400 and 800 ports at the same time really gives you full speed on both ports on your imac? (Check the FW speed in "About this Mac" with both connected). The reason I ask is that when I have a FW800(only) drive plugged into my Powerbook G4,, I get FW 800 speed. However, when I plug in a FW device of any kind to the FW 400 port, both ports drop to FW 400 speed. I have a FW 400 cardbus adapter also, and even if I plug all FW 400 devices into the cardbus adapter, I still only get FW 400 speed out of the FW 800 port.
So I am curious if the ports on the new imac are actually independent (like they are on a Mac Pro), or if they continue to share one FW chip. I wish to have a Firewire audio interface connected to the FW 400 port and a fast hard drive connected to the FW 800 port and still get maximum performance out of each. Any further info 2ould be appreciated.

Fire Wire 800 for Hard Drive - not work

I have a FW hub for FW 400.
Recently added new Formac Hard drive. When connected with FW 400 via the hub into the back of my G5 - works ok.
When I plug the FW 800 cable (that it came with) direct out of the other port on Hard Drive to the 800 port on the back of my mac - nothing.
What am I doing wrong?

Go direct to the FW800 port on your G5.
Also, you can't get FW800 performance if there is anything "upstream" in the chain that is FW400.
Only connect one cable to the FW800 port on the case.
The hub is going to keep everything connected to it as 400Mbps.
Keep it simple. I think you could be ocnfusing your system (and could damage the drive's directory) with it being connected to the 800-port AND a cable from the hub. Just use the native 800-port on G5.

External Drives Won't Mount with SIIG Fire WIre 800 PCI Card

I can't get any drive to mount using this card. It's the SIIG FW 800 3 port PCI card. I've also got the SIIG FW 400 and I think a Belkin 5 port usb PCI card. I've removed the other cards leaving just the 800. I've moved them all around into different slots. Nothing Changed. I've reset the PRAM and the NVRAM. I've Unplugged system and let it sit for a while. I've had only one drive connected to the 800 card and no other 400, 800 or usb peripherals connected. That didn't help either. Again, this is the second card, so I have to assume that the odds of getting to bad cards in a row is a long shot... right? I have to assume that it's the G5 but the other cards work when put into any of the PCI slots. I know all the drives work. I'm just kind of baffled here. Oh, and in the system profiler the drive shows up as "Unknown Device" but it never mounts on the desktop. Also drives connected to the 800 PCI card don't show up in programs like Diskwarrior or Drive Genius. Starting the drive while Disk Utility is open also does nothing. So, I'm at a loss. I spoke with SIIG tech support and they said they had no idea but they could test the card if I send it to the. That would at least confirm or deny if the card is faulty. I think the card is ok and the mac is just messing with it somehow? Any Ideas? Could resetting the PMU help? I've also cleared my cache and defragged and rebuilt the data directory and all the usual utility stuff. So the system is peppier but still no drives mounting on the 800 pci card? Please shout out if you have an idea... Thanks..

I eventually gave up. I will probably get another card at some point but it probably won't be a SIIG card. Even though they are recommended by digidesign I just doesn't seem to want to work with my G5. Maybe it's some kind of weird software conflict blocking the functionality of the card? Don't know. Two cards in a row were non functional. Something is gummin up the works and the PCI slots work with the other cards I have. The only thing I did not try is plugging in the optional power connection to the FW800 card, which is supposed to be optional. I called SIIG and they had no idea what the problem was and they also said that the power plug would not make a difference for the problem I was having. Anyway, I'm gonna keep monitoring posts to this cause I'd love to hear the answer.. but I'm throwing in the towel. Good luck to the rest of you still trying to solve the riddle.

Fire Wire 800?

I have an external firewire drive plugged into the standard fw400 port on my Mac. If I get the right cable, can I plug the same drive in the 800 port and get faster transfers? Or do I need a different drive altogether.
Thanks
Noah

Thanks for for the tip. I'm not sure what type of fw connectors it has, but I'll look. I guess if it's not fw 800, I'll have to buy one.\
Thanks

Fire Wire 800/400 Ports

Could someone kindly advise if On a Mac G5 ... if a FW400 perhiperal could also be used the FW800 port ?
Thanks

Many thanks for your reply - I appreciate your help & mac expertise.
You mentioned that the F800 and Fw400 ports are both on the same bus - will that restrict the current Fw port usage to one port at a time ? ... Without a 2nd bus added via a pci card (Kindly excuse my lack of technical terminology & knowledge)
I need to run a film scanner fw 400 and an ext HD F800/fw400 from a G5 tower at the same time - do i need to install a 2nd bus (via a pci card)?
Many thanks once again

Fire Wire 400 vs 800 vs USB speed

A Fire Wire 800 port has a faster rate of transfer than both the Fire Wire 400 and a USB 2.0. Is a Fire Wire 400 port faster than a USB port and if so is it considerably faster than the USB.

Hi mick1964;
USB 2.0 is the slowest. I know it has a quoted rate that is greater then FW400 but that it burst rate which it is not capable of sustaining.
Generally FW400 is about 40% quicker then USB 2.0 for sustain data transfers.
FW800 is faster then FW400.

Connecting AirPort Express using Fire Wire

Hi, can't see this posted anywhere else. Have been running my MacBook Pro off my AirPort Express quite happily for some time. However recently purchased a Sonos S5 that needs to connect to my wireless router via ethernet. Only problem is the Airport Exp. only has the one ethernet port. So figured I could use the FireWire connection for the Airport/Modem and then the ethernet for the Airport/Sonos.
Only problem is I need to configure the FireWire in System Preferences and despite my attempts at guessing configuration I have no idea what I am actually doing. Not sure if it's an easy answer, but if anyone can help with config I would be very grateful.

Hi, thanks for the response and sorry that I am unclear - not my area of specialty.
Currently I have my airport express router that connects to my modem via ethernet.
I purchased a sonos unit that streams music over the internet and plays it through the unit. It uses its own base station/router to connect to my wireless network so the main unit then becomes wireless and I can move it any where in my house.
As I understand this base unit needs to connect into my router via ethernet. The problem is the Airport Express has one ethernet port and one fire wire port. I was hoping to get around this by using the fire wire to connect to my modem, and then that would leave the ethernet port free for the Sonos base unit.
In case I have just been confusing again the manual for the Sonos refers to the ethernet connection 'use category 5 ethernet cable to connect to a router, computer or additional network device'
This might not be possible, just assumed fire wire would work but no idea how to configure. Possibly it will involve me having to buy a hub (or extreme) to get multiple ethernet ports.
Thanks for your help - I am (obviously) lost here so any advice is great!!

Fire Wire problem on mini (mid 2010)

Hi,
i just bought an external hdd (Seagate GoFlex for MAC 1,5TB) which i want to connect using FIRE WIRE 800, but now I notice that the fire wire port on the mini has a different dimension (much smaller) Can i use it (do i need an adapter? and will this small port power the disk?)
I checked the disk on my 2011 Mac book pro (which has the right size of port) and it works like a charm!
can anybody advise me on this!! thx, as i already opened the disk i cannot return it anymore so i really need a solution on how to use it.
thx
peter

Hi,
can you indicate which adapter to use, and second of all does it power the disc?
thx
Peter

Core Audio Overload - Will a New Fire Wire Unit Help?

I use a G5 2.5Ghz Quad with 6GB of RAM and an Edirol FA-101. I'm finding that the 'Core Audio Overload' is becoming a huge irritant and I've tried multiple driver configurations in Logic Pro 7.2 to correct the problem.
Watching the performance, I had 64% of my processor power idle and 1.79GB of RAM free when it last occurred. Given that so much system resource is idle, my only conclusion is that my Edirol FA-101 is not adequate for the tasks I'm setting it. Before I spend the money, does anyone agree or am I barking up the wrong tree? Can Core Audio overload due to the sound unit being used?
I'm thinking of a Fire Wire 800 unit like the RME Fireface - if anyone has experience of FW800 units I'll be glad to hear from you and from anyone who knows whether it will help Core Audio process information in time.

I'm not using a seperate drive for my Logic files. I've worked through the link you posted on settings several times, and it's Steinberg's 'Halion Symphonic Orchestra' that's crippling my system. I watch the system performance as the song plays and the second core peaks out every time while the Disk I/O meter barely registers a blip which is why I haven't put anything onto a seperate drive, though I certainly shall be.
Will getting Logic projects on a seperate drive work to a greater extent for Core Audio? Halion Symphonic Orchestra uses huge files, but I can't understand why I have such a large amount of Idle system with the Core Audio Overload?
Would an RME Fireface not help Core Audio in its processing? If I can avoid the cost, I will. I'm even using a Pro Care appointment on Tuesday afternoon to see if there's anything else I can do, I'm that desperate!
If I move the Halion Symphonic Orchestra to a seperate drive and then the Logic files to another, would that be more benificial to system performance?
Beer anyone?
