Firewire connection 400 to 800 is the a special cable

I just purchased a new Mac Mini with a 800 Mb firewire and want to transfer files from my older Mini with a 400 Mb. The pin outs are different. Is there a cable available that will connect the two? Will I be able to connect the new Mini to my external 400 Mb Hard Drive?

Do you mean something like this: FireWire adapter?
Other models are available to adapt what you need.
By using an adapter you will be able to use your FW400 drive.

  • 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

  • Ok to have to Firewire disk (one is 800 and the second 400) on the same FW?

    Is it safe to have to external harddrives (type: La Cia "Rugged drive"), disk A is FW800 and disk B is FW400 on the same Firewire bus? I do only have one Firewire bus on my Mac Book Pro..... I did put disk A first in the "chain".....

    The way it works is that the device closest to the computer will set the speed of the connection.
    So, if the chain is set up: Computer>FW800 drive>FW400 drive, the FW 800 drive will function at its normal speed and the FW400 drive will connect at its normal speed.
    Were you switch the order of the drives, both drives would function at FW 400 speed.
    However, there can be other issues at play. For example, a G-Technology G-RAID2 drive will default to FW400 (or less) speeds if another FW 800 drive is attached. Go figure.

  • Firewire connector 400 or 800?

    Last summer I bought an iMac intelcore 2 duo, reconditioned by Apple. I have the surprise that the firewire connector doesn't suit to my firewire cable. The firewire connector on the iMac is rectangular, with 4 pins on one side and 2 pins on the other side.The cable firewire connectors, I usually used, are rounded upside, with 2 X 3 pins.
    The iMac firewire connector would it be a 400 firewire, although on the iMac info the Firewire is said to be 800?
    What can I do to use that firewire port?
    Thanks to reply

    or you can get this cable http://store.apple.com/us/product/TP320LL/A?fnode=MTY1NDA3Ng&mco=MTA5MjUxNjk
    this adapter is 800 to 4-pin. http://store.apple.com/us/product/TU942LL/A?fnode=MTY1NDA3Ng&mco=MTA4NDQ3ODk this is the cable is usually used on camcorders.

  • Running FW 400 and 800 at the same time

    Somebody told me there are problems running a 400 drive and an 800 drive at the same time. Is that true? I'm considering what drive to buy for audio on my macbook which only has one 400 and one 800 port. Will I be able to back up from the 800 to a 400? The 800 drive has one 400 port so I can't daisy chain it as a 400. Does the 800 bus offer any advantages to audio recording besides faster archiving?

    There shouldn't be any problems, and I've never heard of any.
    However, chaining or bus sharing FW400 and FW800 (on any Mac) will always pull the overall bus speed down to the slower FW400 transfer rate. Which, when working with audio, will make no noticeable difference at all.
    It's the same when bus sharing USB1 and USB2, the slower connection always takes precident.

  • 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.

  • Error -36 when reading/writing with firewire drives (400 & 800)

    This is only happening when I connect the drives to my G5, but the drives work fine on my MacBook Pro. I first thought I had a problem with my drives, but then when they worked on my laptop I figured it must be a problem with my G5. One of the drives is a smartdisk firelite drive connected via firewire to the front of my G5, the other is a G-Drive connected via FW 800 in the back of my machine.
    Any ideas of what I need to do on my G5 to fix this issue?
    Thanks!

    Hi-
    The error is an I/O error. One possible cause is low power on the firewire bus, or, the drives require more power than is available. Placing a powered hub between the G5 and the drive may be the solution.

  • Yosemite won't Boot from External SSD with Firewire Connection

    Seeking help, I boot from external SSD drives from my 2010 iMac. I recently installed Yosemite on an External SSD with a firewire connection and all went well with the installation and first boot. After completing set up and restarting my iMac Yosemite will no longer boot from the firewire connection it will boot to the loading bar and then get the dreaded Goest Buster Emblem, if I swap out the SSD to USB connection it boots normally. I have 6 SSD Drives with Mavericks and Lion installed on that will boot from the Firewire Connection.  Any suggestions ?

    Additionally when testing while the SSD is connected to a USB Connection and booted if I attach any firewire device they are not recognized or connected to the operating system.

  • Front firewire connections

    My 845PE Max2 MB gives me 3 IEEE 1394 connections on the board. I am using two of the three available connections for the S-Bracket on the rear (J1394_1 & J1394_2 and they operate OK) and trying to get J1394_3 connected to the front panel. I have an Antec case with six wires to front panel. Here is how I have them connected to J1394_3:
    Pin 1 - TPA +
    pin 2 - TPA -
    Pin 3 - Ground (VG is Antec ID)
    Pin 4 - open
    Pin 5 - TPB +
    Pin 6 - TPB -
    Pin 7 - Power (VP is antec ID)
    Pin 8 - open
    Pin 9 - key
    Pin 10 - open
    It's not working! Ok, what am I doing wrong. Can anybody help?

    My buddy had that same problem with his Antec Sonata case, it seems that the front Firewire connection was wired wrong on the case, from the factory.  He had to take the wires out of the connector, and rewire it to work.  Two of the connections were backwards, like the person was looking in a mirror when he did it  Check them out really good.

  • Firewire connections not supported....

    I had recently upgraded from a 20G to a 60G video. I honestly dont know what generation my first one is, but it is white and does not have a color screen...Anyway, on the older one, I am able to use firewire to load music from Itunes. When I tried to plug in the new one, using the same library, it says 'firewire connections not supported. Use the USB cable provided'. I am hoping there is a setting that I can flip to change this.

    No you can't - the current release of iPods only support synching through USB.
    FW accessoire can be used for battery charging only.

  • Is anyone having a problem connecting 400 firewire thru an adapter for the 800 firewire port on a Macbook Pro 2011? It does a kernel panic every time I connect it. Is there a "proper way" to connect it?

    Is anyone having a problem connecting 400 firewire thru an adapter for the 800 firewire port on a Macbook Pro 2011? It does a kernel panic every time I connect it. Is there a "proper way" to connect it? Just in case it makes a difference I am trying to hook up an Avid Mbox Pro for Pro tools.

    What is the part number and model of Firewire adapter?
    I have used them in the past without any problems whatsoever.

  • I am using IMovie 11 with a new iMac.  Unable to import video from a Panasonic PV-GS400 mini-DV camcorder using a Firewire IEEE 1394 400 cable connected to a Firewire 400 to 800 adapter which is then connected to a Thunderbolt to Firewire 800 adapter.

    How can I get iMovie to recognize my Panasonic PV-GS400 as a device so I can import video to my iMac?  I have a FireWire IEEE 1394 400 cable connected to the camcorder.  Since my new iMac has only Thunderbolt ports, I purchased a Firewire 400 to 800 adapter to connect to the cable.  I also purchased a FireWire 800 to Thunderbolt adapter to connect to the computer.  My camcarder is still not recognized.

    I would suggest that you try a 9 pin to 4 pin Firewire Cable along with the Firewire to Thunderbolt adapter.
    Those Firewire 400 to 800 adapters do not seem to work well with iMovie.
    The 9 pin to 4 pin cables are available at reasonable prices here, for example.

  • Firewire specs, and 400 to 800 connection

    I need to connect an Epson Perfection 4870 scanner to either of my 2009 Macbook Pros.
    The scanner has a conventional 400 firewire socket - how many pins?
    The Macbook Pros each have an 800 firewire socket - how many pins?
    Should I be looking for an adapter or a cable with 400/800 plugs?
    Any help with locating the right cable/adapter would be much appreciated.

    Yesterday I bought a 6 ft. Belkin FireWire 800/400 9-pin to 6-pin cable from my local Apple Store for just such purposes. (The Apple part number is TP320LL/A)

  • MAC G5 2004 are the 400 and 800 firewire busses interconnected?

    When I plug in a DV camera to the 400 firewire buss and go to system profile/firewire, the DV camera doesn't show up.....but, when I turn the firewire hard drives off (pull their power) thus disconnecting them from the 800 firewire buss, the DV camera shows up....
    If I have my firewire external drives connected to the 800 firewire port, and the DV camera connected to the 400 firewire port sometimes (not often) the the dv camera works, most of the time it doesn't..... help!
    The only way I can get the dv camera to work is to disconnect the firewire hard drives from the computer then all is good in the land of "MAC).....

    The external hard drives have their own power.....turns out that the 400 and 800 firewire busses are the same.....What Apple did was an 800 firewire buss and has 1 port located on the rear of the tower and 2 400 ports (one one the front and one on the back). The 2 400 ports are equal to the 1 800 port, so when you use one 400 port and 1 800 port the 800 port becomes another 400 port. In other words.....I only have 1, 800 buss and not an 800 buss and 2 400 busses....pretty tacky if you ask me......also, I learned that the Canon DV cameras (ZR70MC) is a real hog when it comes to firewire, so, when I have my external hard drives plugged into the 800 buss and the Canon plugged into the 400 buss, it's on overload and their is no buss protocal for who uses what. Which means if the external drives are using the buss the Canon is out of luck......The solution is to install a separate firewire card and plug either the Canon or the drives into it thus freeing up the internal 800 buss for other uses.
    The workaround is for me to unplug the power to the external hard drives, plug in the Canon, capture all of my material onto the internal drive, once I've captured all of my files, remove the Canon from the buss, powerup and re-mount the external drives, then, move all of my captured files over to my work space which is located on one of the external drives......what a pain in the butt......but that's the way it works.....

  • Using both firewire 400 & 800 at the same time?

    I have a 20" Imac 2.66ghz, and I have a 1TB WD Studio Edition My Book attached to the firewire 800 port. It is partitioned in to two 500GB partitions, one for time machine, and one for media.
    I have a Canon MD101 DV camera which I have been trying to import video from, not very succesfully. I had given up, and was going to go to an Apple store to try and sort out the problem.
    I have bought a new firewire cable with gold contacts to see if that would improve the situation. Today I managed to import direct from the camera, but I hadn't realised I had disconnected the hard drive by mistake.
    On further investigation it would appear I can use either firewire ports seperatly, but not together. My Camera is recognised evrytime by Imovie if the hard drive is disconnected, but not if it is connected.
    The problem I have is that the media partition on that hard drive was for my videos imports.
    Are there any settings that would enable both firewire ports to be used at the same time?

    Hi Peter
    Try a 4 to 9 pin FireWire 800 cable and connect the camera up to the spare FireWire 800 port on the back of the WD Studio Drive.
