Can You Daisy Chain Firewire 400 and 800 Mixed?

I would like to purchase an External Drive. I'm looking at a FW800. What I'm wondering is, Can I daisy chain devices mixed in.
I Want to run a FW800 Bilingual cable from my Powerbook to the External Enclosure. From the Ext. Enclosure, I'd like to have take my second FW800 port and take a cable that converts Firewire 800 to Firewire 400 and plug in another item. Is this possible?
Can I mix and match FW devices using separate protocol in a daisy chain configuration?

Russ,
Yes, it is possible. I have a drive that works on FW800, FW400, or USB2. Connected to the second FW800 port on that, I have an adaptor cable, a FW400 cable to a FW400 drive, and another FW400 drive connected to that . All 3 drives are on the desktop of my PowerBook. When I read your post, I had the only first drive connected to the iBook with USB2.
The only problem I've run into was trying to copy a 200G drive on FW800 to a 250G drive on the FW400 port on the PowerBook. Working overnight, it managed to copy ONE Gigabyte! I hooked them up as they are now, and copied the whole shebang in about 45 minutes
I picked up an empty drive case, 800/400/USB2 combo from OWC and a 250G Maxtor drive at CompUSA for about $100 less than I could get a 250 FW800 drive anyplace. http://www.macsales.com

  • Daisy-chaining firewire 400 and firewire 800?

    I would like to daisy-chain two Western Digital MyBook Pros to a Macbook:
    - FW 400 from Macbook to first drive
    - FW 800 between the drives
    Would this work or not? I have one of those, they have 2 x FW 800, 1 x FW 400, 1 x USB at back.
    (If not, I'll buy a 'Premium' which has 2 x FW 400, and 1 x USB..)

    I'm not sure if the hardware in the first drive, that's connected by firewire 400 is "smart" enough to jump the data over to the FW800 connectors for daisy chaining.
    Just pulled this from the WD site. I would say this indicates it would work. You won't get more speed but they should work daisy chained. This indicates the drive is smart enough to do this.
    +Question: Will Western Digital FireWire 400 (1394a) external hard drives work connected to a FireWire 800 (1394b) port?+
    +Answer: The FireWire 800 Specification (1394b) states that FireWire 400 devices will work while connected to a FireWire 800 (1394b) port. The FireWire 400 cable (4-6 pin or 6-6 pin) will not connect to a FireWire 800 port (9 pin) therefore you will need to connect the hard drive using a FireWire 400 to FireWire 800 cable (1394a to 1394b cable). These cables are available at most computer stores.+

  • HT5299 Can 2 daisy-chained firewire-800 drives be connected to 1 Thunderbolt-to-Firewire adapter?

    Thanks Steve!
    One more question: Stayed throughput speeds more or less the same as original Firewire (since all my movies are on external disks) or has it become significantly slower?
    I haven't done a careful side by side quantitative comparison of what I had on the older Macbook Pro (which had three Firewire800 disks chained together via FW800) versus the new Macbook Pro (which has thunderbolt into which I have connected three FW800 drives daisy chained via the adaptor), mainly because my employer supplied me with these computers and required I turn in the old one when they replenished it with the new one. However, I can say this -- one of the FW800 externals is used for Time Machine, another for making entire disk clones, and the third is for misc storage. I have seen Time Machine start up during a disk clone (with SuperDuper) and there seems to be no impact. The disk cloning is generally pretty intensive on disk and cpu resources, but thunderbolt seems to have a much bigger capacity for throughput than firewire and hence can apparently accommodate multiple streams of FW800 data going back and forth with no apparent impact on each other. The main limit seems to be the FW800 speed itself, not thunderbolt. I see ~ 60 MB/s or more which is as much as I have ever seen on FW800. Ultimately, the ideal setup will be thunderbolt drives daisy chained together, I would expect hundreds of MB/s, but I don't see many of these thunderbolt drives on the market yet. Even better would be solid state drives ...

  • Firewire 400 and 800 problem ? Need confirmation

    OK, I have been running 2 external Lacie HD's over a USB hub into my MacBook Pro. A couple of weeks ago I decided that I needed more storage so purchased 2 Western Digital MyBook Pro's at 500GB.
    I got these two specifically because I knew they supported Firewire 800 and wanted to take advantage of the high speed connection.
    All is going well until yesterday.... Let me explain my set up. Firstly I am a DJ and use a Firewire Audiophile soundcard from M-Audio, this connects to the 400 port on my MacBook Pro, and the HD's connect to the 800... When I play music I get audio drop outs... I have looked through the forums and I am under the impression that both the 400 and 800 ports on my MacBook Pro run on the same connect, so is this the cause of the audio drop outs ?
    I connect the 2 HD's via USB and have no problems, am I right in thinking that I have wasted good money on getting 2 HD's that I'm not going to be able to use the 800 port with ? When I run the audio through the internal soundcard I get no drop outs !
    Also.... Just to annoy me even more I have a 20" cinema display so if I have use USB I decided to connect the two HD's to this and then to the MacBook Pro, now the problem here is when my MacBook Pro goes to sleep one of the HD's wakes up the MacBook Pro as it has been removed incorrectly ??? Do I now have a problem with one of my USB ports on the cinema screen also ????? I have put my iPod in the port and no problems ?
    Does anyone know how I can solve these problems without having to spend even more money ?
    And can someone confirm if the 400 and 800 ports are on the same connection, if so, whats the point ???
    Thanks
    - Neil

    neil,
    I wouldn't do that right away.. USB audio interfaces are usually at the more consumer end of the market, I don't think it's the best way to go just to solve your problem.
    did you read the part in my post about PCexpress cards that give you a totally new and independent FW800 bus? seriously, I think this is your best bet. these cards first came out when the original series of MBP didn't have FW800 on them (only 400) much to the consternation of video pros.. so 3rd party vendors made a card solution. as I said, they aren't expensive, I would have thought around or under $100 US. connect one of those to your MBP's express slot and your problem is solved. you'll have a powerful, dedicated FW channel just for those FW800 drives you bought. then, your m-audio interface will be fine. and even if you still want to get rid of it and get a better interface, you won't be forced to go to USB which generally means opting for a lower end of the market interface.
    also one other thing.. I don't know what your actual audio i/o needs are. but if you only ever work with stereo out and stereo in, ie, you never need more than 2 physical outputs and 2 physical inputs, then you have other options. the MBP (and in fact all macs) have optical digital audio built in. you can buy a 2in 2out digital to analog/analog to digital converter and connect it to the opticals. then, you'll never need to worry about FW or USB bandwidth ever again, nor will you ever need to think about drivers or compatibility or updates either.
    on my MBP I use logic pro. and on this system, I only ever need a stereo out to hear what I'm working on with good quality.. and when I record actual audio tracks, it's only ever one source at a time, like a mic input or an instrument. so I do not need an interface at all, I use the opticals and I love it. I bought a mindprint trio, not the USB one, but the one that uses optical i/o. it just connects to the same connectors on the MBP that you would connect headphones or a mic, but obviously uses the digital optical signal not analog audio. it sounds really very good. the trio itself is a very handy little box that conveniently lets you do a lot of things to work comfortable when recording. and I just use built-in sound, no drivers needed ever, which is very much a rare relief in the audio world, believe me.
    anyway, hope this helps. and seriously check out a card for FW800, in my opinion it's the best solution to your problem no matter which way you go.

  • Audio interface for 24" iMac - conflict between firewire 400 and 800?

    So, what I have now:
    2.8ghz iMac, latest model, newest firmware, running OS 10.4.11, connected to an M-Audio Ozonic Firewire 400 interface, and I was hoping to run said interface while ALSO connecting a firewire 800 hard drive for samples, or for recording to.
    Alas, as soon as I turn on the firewire 800 drive, a model sold by Other World Computing and containing an Oxford chipset, all audio stops on the Ozonic keyboard and is replaced by clicks and pops. The only way I've found to get the audio back is with a complete restart of the system, with the firewire 800 drive OFF.
    For those of you who aren't familiar with the M-Audio device, it's a small keyboard and firewire audio interface in one unit. Perhaps not the highest quality, but my Powerbook G4 1.67 with firewire 800 CAN run both the Ozonic and the firewire 800 drive at the same time. With no interruption in sound playback.
    I did some research and discovered that in the iMac I bought, the two firewire channels, 400 and 800, appear to be on the same PCI E bus, and perhaps will NEVER work together.
    Is that right? I thought the whole point of firewire was how it's able to negotiate such communications and work seamlessly with other firewire devices. I know, I know, I'm living in dreamland, it's just sad that a much older Apple product (my PPC notebook), can do something a brand new model cannot. Sigh.
    Any advice? Any chance 10.5 fixes this?
    If not, should my next audio interface be USB 2.0? Any thoughts from the Audio pros out there (besides 'you bought the wrong machine) would be great.

    Sorry I can't help with your specific query as I have never used that Audio hardware.
    I am a video man myself and went for the 24" 2.8Ghz iMac as i believe the Firewire 400 and 800 Buses are seperate. I know on older iMacs and even the MacPro the FW800 and 400 buses were on the same bus and when connecting a firewire video camera to the FW400 bus, the 800 would lower it's speed to 400 to accomodate or in some cases would lose the connection all together.
    I currently have a FW800 Hard drive connected to the FW800 port and a video deck in the FW400 port and they both run at full speed 800/400 respectively.
    This leads me to believe Apple have fixed the Firewire sharing problem.
    I know it's no help but just though I would share my experience with the Firewire on the new iMac.

  • Can't daisy-chain Firewire drives reliably from 1-port Powerbook. Hub??

    I have found that I cannot get a daisy-chained Firewire drive to mount more than 50% of the time. This problem doesn't happen with Tiger with the same drives. I have tried 4 different brands of late-model Firewire drives (Iomega, Smartdisk, Maxtor, and Seagate) with different cables and what happens is that a drive that is directly attached to the 12" Powerbook will mount, but the second chained drive fails to mount a majority of the time. Since I only have one Firewire port, this is preventing me from using more than one drive at a time, and I lost two Firewire drives to corruption today. Three out of four partitions lost contained bootable backups of Leopard and Tiger. Ouch!
    This issue could prevent from using Leopard with my Powerbook, which is supposed to be Leopard-compatible. I can't remake the clones too easily with only being able to attach one drive at a time. I am thinking I will order a Firewire hub and try that, but I am not sure if that would be a solution, and I am wondering why I can always daisy-chain under Tiger, and not under Leopard. Does anyone have experience with Firewire hubs and Firewire operation details? Will I be able to get reliable Firewire with a hub?

    I have exactly the same problem !
    I have found this :
    Using Multiple FireWire Devices at the Same Time
    Power Macintosh computers can transfer perfect digital video (DV) on FireWire when no other devices are using the FireWire bus. If you have problems transferring digital video, make certain that no other FireWire devices are being used at the same time. Turning on a DV camera that is already connected may cause a FireWire hard disk to stop working. If this happens, turn off the camera and verify that the hard disk has recovered. Then unplug the FireWire cable from the camera, turn the camera on, and reconnect the FireWire cable to the camera. Check with the hard disk vendor for a possible firmware update to prevent this problem.

    At the moment I can't upset what I'm doing to test it but I intend to do that as soon as I finish copying transferring...
    I have the following device attached to different firewire ports:

  • Firewire 400 and 800 together

    I have 2 external HD firewire:
    120Gb Firewire 400 and 500Gb Firewire 800.
    They work fine EXCEPT when I connect both HD to my PB.
    I have to use 1 at a time, not together.
    Do I have to do something to use them togheter?
    Its both LaCie HD
    PB G4 17" 1.67/1x1Gb/100Gb   Mac OS X (10.4.8)  

    I tried once hooking a 400 drive into the 400 port, and an 800 drive into the 800 port, then transferring a big file between them. A 1.2 GB file finally stalled at about 10 hours. I then daisy chained the 400 into the 800, and the 800 to the PB, and that worked fine. I now frequently hook 4 of them, only 1 of which is 800, and as long as it is hooked thru the 800 to the PB, it works fine. If I unhook the 800, and plug the chain into the 400 port, that works fine. I don't have the right cables to go the other way, but that would slow down the 800. I can hook it in as 400 in the case of hooking it all up to my MacBookPro without FW800.

  • Is firewire 400 and 800 on the same bus?

    I have heard of the problems putting a camera and external hard drive on the same bus for capturing video. Does the 400 and 800 ports share the same bus and will using both with one connected to an external 800 drive and the 400 port for the camera be a good solution for capturing video?
    Much appreciated.

    yes, on PowerBooks w/1394a and 1394b ports, and on the G5's with 1394a and 1394b ports, they all share a common bus
    sometimes if you have a lot of activity on the bus, you might have some frame drop out with a camera connected (but this is not a constant)
    it never hurts to add a PCI card or cardbus card for PowerBooks and create a second FireWire channel that is independent of the builtin ports

  • Logic Pro 9.1.7 firewire 400 and 800 not working

    I am having issues with Logic Pro 9.1.7 recognizing FW 400 and 800 connections, and/or my FW interface (mbox2 pro).  When I open up LP I often do not hear any sound and have to reboot or reconnect FW cables, per another post suggestion with ProTools 9.  After 30 minutes of restarting twice, unplugging / plugging in FW cables, turning off/on FW drives, it's finally up and running. 
    But the weird thing is that sometimes it opens up fine and other times it does not.  I don't understand this variable, as my setup always remains the same.
    I am guessing this is a Mac OS issue, but I'll list my setup in case anyone has any suggestions:
    MacBook Pro OS 16.6.8
    Mbox2 Pro interface (blue) - connected via FW 400
    Firewire drives on both 400 and 800 connections
    I realize this could be a host of issues other than Logic Pro 9, such as Audio Midi Setup (which often doesn't recognize my Mbox2 Pro).  But again, thought I'd start here.
    thanks

    If Audio MIDI Setup cannot see/recognise the MBox, then Logic will be unable to see it. Audio MIDI Setup is at OS level: if your MBox does not show up it is likely to be:
    Driver issues (highly likely)
    Cable Issues
    FW socket issues: hardware fault.

  • How many FW devices can you daisy chain?

    Have a new iMac w/ one FW800 port. Need to daisy chain eight FW800 hard drives, two FW400 hard drives, and one FW400 DigiDesign Digi002 ProTools mixing board. I was planning on daisy chaining all the FW800 drives then coming out of the last of those with a FW800 to FW400 cable into the first FW400 drive, daisy chaining to the 2nd FW400 drive, then daisy chain from it into the FW400 ProTools mixing board. I know that's a lot of chaining but at the moment those are the devices I have to work with. I have A LOT of video and audio information I need to retain. Seems to me that I read somewhere about a maximum length a firewire daisy chain could be but haven't found any more reference to it when I just looked. All of the devices have their own power supplies so I don't believe they will be drawing much, if any power from the chain. Anybody know of any problems with this setup?

    Thanks for the info.
    I've tried several scenarios and combinations what I've found is that I can put all the FW800 drives in a daisy chain then put the 1st FW400 drive in and lastly the Digi002 mixing board (which is FW400). When I try to add to this any more drives I get unpredictable results. I have therefore bough another 2TB external drive and hooked it up through USB 2.0 and copied many files to it from the older FW400 drives as well as the only FW800 drive that ever game me headaches. It should be noted that it is a Western Digital My Book drive. It seems like it would be a great drive having FW800, FW400, and USB 2.0 connections. In practice, however, I have had LOTS of problems both on my Macs and PCs I tried using it on. I recommend strongly that you avoid using any MY Book drives. I'm having better luck with practically any other manufacturer, including what I would normally consider no names like SimpleTech and Buffalo. Those drives seem much more stable.

  • Firewire 400 and 800

    I use my powerbook for digital video editting. I connected to dv camera to the firewire 400 port and connect an external hard drive to the firewire 800 port. Recently when doing this the device that is connected last does not show as being connected. If I connect the the hard drive first them imovie does not show a camera connected and likewise if I connect the camera first then the hard drive does not mount on the desktop. If anyone has any ideas on what I can do to get my firewire ports to work simultaneously please let me know.

    I have the same issue and I thought the ADS unit or the Hard Drive was bad. If I disconnect the FW800 cable from the external HD, then repower the drive, it will boot and I can plug the FW800 back in and it will mount on the desktop.
    FOUND A FIX!!!!
    I found this in the knowledgebase:
    Short Version to reset NVRAM and it fixed my boot issues with external FW800 HD.
    Boot Mac while holding down the Apple-Option-O-F keys
    at the prompt type:
    RESET-NVRAM (press enter)
    RESET-ALL (Press enter)
    Then your mac will reboot.
    After I did this, my drive mounts normally!
    If you want the whole thread, search for "reset NVRAM".

  • Can you daisy chain 2, 3 or more Core Duo Minis VTech style?

    I'm interested in the mini(s) if I can daisy chain them to spread the workload on various minis....much like System X in Virginia Tech. I'm trying to use my $2K budget the best way possible.
    If not, can I at least run logic on one and use the other as a node? If so, do I need to consider how much memory EACH has, or just the main mini?
    Thanks in advance.
    SX

    Well, if 2 nodes is all you need you'll probably be fine using just the Giga Ethernet. Just pick the tracks with more processing to do if your nodes aren't working hard enough. More info...well you can find it in the Logic forums....what else do you need to know? You'll want a Router or just use 1 on FW and 1 on Ethernet. You just need to to network them, create a private network (noone else needs access to them). Install the node app as a startup item. Leave it running for weeks at a time.
    If that's all you need it for then start with 1 GB and make sure you can follow upgrading procedures. I am pretty sure it is only recommended that you install in pairs, if you buy 2 1 GB sticks put one in each and leave the factory sticks in the other slot you should be OK.

  • Can you daisy chain time capsule??

    A while back I tried to daisy chain 2 lacie drives off of airport and that didn't work. 2 questions:
    1/from what I have read I can connect this to an airport extreme and that will work just like my lacie does now...
    2/Does anyone know if I would be able to use all 3??
    Thank you

    I'll my 2cents worth here as there's some assumptions being made in these responses that IMO are misleading the author of this thread.
    1. Apple fully supports using Time Machine with the internal HDD located in the Time Capsule.
    2. It's a stretch to assume Time Machine can also safely (and with Apple's full support) also support USB AirDisk(s) attached to the Time Capsule. Recall that the earlier version of Time Capsule was the AEBS (10/100 or GbE) supported AirDisk(s) but their use with Time Machine was pulled from Leopard just a week before Leopard was released on Oct 26, 2007. At this time Apple has not made public what their future position is or will be in bringing back this feature.
    So for those that are thinking of using USB drive(s) with Time Capsule and hoping to use them with Time Machine I say be forewarned or at least wait for Apple to publically announce support for them before investing in the Time Capsule.

  • Can you Daisy Chain the WRT54GS?

    Hello,
    I've recently purchased three LInksys WRT54GS. I've read the FAQ but not seen my exact problem listed.
    Can the WRT54GS (the super G version) be Daisy Chained (1 router, 2 as APs with dhcp disabled) and if so which port should link to from router #1, port1 or the "internet" port.
    If I use the port marked "internet" than I get great signal strength but a lot of drops. However if I use port1 on each of the routers I'm using as AP's then I get low signal strength but less drops.
    Configuration so far:
    router-1 (dhcp enabled)
    ssid - router1
    channel 1
    192.168.1.1 /255.255.255.0
    router - 2 (dhcp disabled)
    ssid - router2
    channel 6
    192.168.1.2 /255.255.255.0
    router -3 (dhcp disabled)
    ssid - router3
    channel 11
    192.168.1.3 /255.255.255.0
    thank you for the help!

    These answers are incomplete oin their face:
    You described the config as:
    router -3 (dhcp disabled)
    ssid - router3
    channel 11
    192.168.1.3 /255.255.255.0
    which tells nothing about the "WAN and LAN addresses cannot be the same"
    The "Local IP" address cannot be the same as the Internet (WAN) address
    "Internet Setup" or "Netword Setup"?
    It is as if you have never looked at the config screens in this router.
    How is your local PC connected to the second router supposed to get the DHCP address when there is no route to the first router? Then, how can you connect to the second router to configure the route? I set a static IP for my PC and I can connect to the second router, but even after setting a route, which cannot have a 0.0.0.0 gateway, cannot ping the first router.
    Let's tell the whole story here, the complete configuration. It's a simple expectation to have a second router hard-wired to the first router, and the secod router providing "distant" wireless access to the network.
    The whole story folks?

  • Can you daisy chain two Compact DAQ systems together?

    Greetings everyone,
    I have a signal conditioning application and I have been looking at the Compact DAQ Platform as a solution.
    I have a total of 16 TC's channels, a few DIO and a few Analog Out requirements.
    I can basicly meet these needs with a single cDAQ system but I would like to have room to expand more in the future.
    Does anyone know if it is possible daisy chain more than one cDAQ system together or if it woudl be very difficult to program and run two seperate DAQ systems from my computer.
    Any help would be greatly appreciated.
    Thanks,
