  • Daisy chaining external hard drives and a video camera from a single firewire 800 port on my imac

    I have only a single firewire 800 port on my imac and want to know if I can daisy chain two external hard drives and my video camera, please? If not is there another solution using USB 2?

    Are the external HDs self powered or powered by the FW port?  If they are self powered there should not be a problem. If they are port powered they may put a strain on the port's power output but I'n not positive on that.

    Hi Jessica,
    No, the SD slot will not work, you need an ExpressCard/34 slot.
    I do not know if it works with cameras, but with two or more HDs, if the first one has two FW ports, you can "daisy chain" one or more additional HDs from it.

  • Firewire 800 Port back to life after power shutdown?

    I experienced a strange event and would like to share it with you for feedback and comments.
    During several days the external hard disk connected to the Firewire 800 port of my IMAC caused me increasingly problems, and eventually the disk would not mount at all on the desktop. I connected the disk to the FW800 port of my portable and the disk worked quite fine. I concluded that the FW800 port of the IMAC was damaged. I was preparing myself to contact Apple to get the IMAC repaired.
    Then recently we had a general shutdown of power in our town, for several hours.
    When the power came back, I had the idea to reconnect the external disk to the FW800 port, and miracle, the disk mounted immediately and has been working fine since.
    Is is possible that the ports of the computer come back to life after a power shutdown? How is this possible?
    Can I conclude that it is recommended to disconnect a computer from time to time, just to reset some parameters?

    Yep, both USB and Firewire ports can get in into a "bad state" and only complete removal of power will reset those chip sets.
    Unfortunately, when you power down the computer there is always a bit of power still applied to the motherboard to keep things alive and this usually includes powering the ports to do stuff like detect when a device is plugged in or wants to wake up the computer. The downside of this is when a bus/port chipset goes into a weird state, locks up, etc., simply power cycling (shutdown & restart) the computer won't work.
    So first thing to try is resetting the chipset and to do this you have to power down the computer and completely unplug the computer from the wall power (unplug the power cord to your Mac). Also unplug everything from the Mac's ports (USB, FW, Ethernet, etc.) to make sure no parasitic power is still there to keep the chipset alive. Now let it sit for a minute (give those big power caps in there time to discharge). Now plug stuff back in & start up the Mac. Now see if your USB or Firewire ports work any better.
    Even Apple acknowledges this occasional issue...

  • Using the firewire 800 port for my firewire 400 devices

    I will be purchasing, at long last, a new mac mini to replace my faithful and well behaved G4 mac mini. I have a 20" cinema display and an external firewire 400 backup drive with the same form factor that sits below the mini. I would like to continue to use these peripherals as well as my video camera DV out. Ideally, it would be cool to have a FW800 hub that had both 800 and 400 places to plug my peripherals, but I don't see that available. Should I get a hub and adaptors for the fw400 components I want to add, or use the hard drive with an adaptor to the mini, then use the FWports on the drive for the monitor, and whatever else I want, thereby using the drive as a hub...
    Any advice to this ignorant question would be appreciated.
    Thanks,
    Paul

    Since Firewire 400 devices still operate at Firewire 400 speeds regardless of whether or not they are connected by adapter to Firewire 800 ports, the best thing to do is just get a Firewire 800 to 400 adapter, and attach it to a Firewire 400 hub known to be able to do all the functions you desire.
    Note, migrating to Intel Macs from PowerPC Macs is not as easy as the Migration Assistant, as this user tip explains:

  • Is it possible to convert a firewire 800 port to a USB 3.0?

    I have a mac-mini from 2011; one generation before they switched to USB 3.  Is there any way of converting the firewire 800 port to USB 3.0, that would allow me to take advantage of newer, high-speed peripherals?

    Unfortunately, getting a new computer is cost prohibitive.  The high cost of Thunderbolt peripherals makes that unlikely, as well.  It seems silly to invest in further Firewire products--when you can find them--given the switch by Apple.

  • IMac 21.5",3.2 ghz i3. has dead firewire 800 port.

    Like it says firewire 800 port does not work. I plug in a known good ext HD. With known good cable. Power light on HD comes on & I can hear it spinning
    but it never mounts to desktop. Doesn't show up in Disk utilities either. HD mounts fine if I use usb port. I know FW 800 port on HD & cable are both good
    because they work fine on friends 27" iMac. Anybody have any ideas or suggestions. I would really appreciate it.
    Thank you in advance
    HAPPY HOLIDAYS

    I have tryed that. I've also tryed resetting the SMC, & the PRAM. Thank you for the suggestion.
    From what I've been reading on this site, it sounds like I don't have any choice but to bring the
    iMac into the service center. I am glad I got Apple care. Otherwise I would be screwed. My iMac is just over 1 year old. Once again Thanx for your time & help. Appreciate it. Have a Great Day

  • How do I capture tape-based media to my external hard drive?  There is only one firewire 800 port on the back of my I mac.  The manual says to import tape footage directly into fcpx, but then I lose my external hard drive.   thanks for your help.

    In FCP X How do I capture tape-based media (hdv clips)- which I want to import-to my external hard drive?  There is only one firewire 800 port on the back of my I mac.  The FCPX manual says to import tape footage directly into final cut, which works, but then I lose  my external hard drive    Do I  have to import it into an event, then copy it over to an external hard drive?  On Larry Jordan's tutorial, he has 3 external hard drives that show up on his monitor WHILE he imports his tape based media.  How is that done?  I can only get either the camera to appear OR my external hard drive.   thanks for your help.

    Thanks for your response, but that doesn't solve the problem.  Yes, the LaCie hard drive has 2 firewire ports-
    I have always done what you suggest (works fine in FCP7), but in FCPX when I do that the camcorder icon
    does not appear.  It only shows up when I DIRECTLY import the footage via firewire.  ????

  • Firewire 800 port on new MBP not mounting Lacie rugged 500GB drive

    Hi all
    I've just purchased the new MBP 17" and my Lacie Rugged 500GB drive will not mount.
    It will mount over USB though.
    I've tried three different FW800 cables and no result.
    There are some posts around 10.5.7 update issues, but I've tried everything listed and no dice.
    Any help would be appreciated.

    I had a Western Digital My Passport Studio model like that. It has nothing to do with cables or your laptop. It has to do with manufacturers who fail to adhere to the proper power standards for the interface. Basically, if the drive demands more power then the port will give, it is never going to work.
    I returned my WD to Apple for a refund, and instead tried a SeaGate FreeAgent Go firewire 800 drive. It has worked flawlessly over Firewire on my MacBook Pro, and it even came with both a Fire 800 cable, a firewire 800-to-400 cable, a USB cable, and a special USB power cable so you could draw additional power off the USB ports if a firewire 800 port wasn't putting out sufficient power. That's why I bought it - figured one way or another it had to be able to work on bus power (even if it had taken both the firewire and USB bus in combo to do it).
    Another option I've had good luck with in the past is OWC Mercury on the Go drives (eshop.macsales.com). These have always worked fine on bus power for me, but they also have an optional external power supply too, just in case.

  • Is there an adaptor or interface that will allow me to connect a thunderbolt device to my late 2011 Mac Pro Firewire 800 port?

    Is there an adaptor or interface that will allow me to connect a thunderbolt device to my late 2011 Mac Pro Firewire 800 port?

    lllaass is correct.
    To use ThunderBolt devices, a computer must have left the factory with a ThunderBolt port.
    There are no known work-arounds, and there are not likely to be any because Intel controls the chips and is not interested in anything less than the full [including Video features] implementation.

  • New imac has only one firewire 800 port?

    Is there a hub or repeater you can use instead of daisy chaining. Can't figure out why my old imac has two firewire ports and the new imac has one. How are others managing multiple hard drives? I wish to use a hub for my firewire connections. What is the best way. thanks

    You can locate Firewire hubs however they are expensive. I have had 3 Firewire 800 external HD's daisy chained together for 3 years that work flawlessly. The drives I have come with 2 FW 800 ports so this is quite easy, there are several top quality external HD's that are similar including:
    OWC Mercury Pro line
    Lacie Quadra D2 line (this is what i have)
    G-Tech G series line
    All of these drives have similar specifications and are all high quality products. I think you will find them to be the most recommended on these forums.
    BTW your old iMac had 1 Firewire port and 1 Firewire 800 port not 2 firewire ports.

  • Adding Firewire 800 ports

    Hi there
    Anyone know how I add / install Firewire 800 ports to my mac pro and can recommend the appropriate card to get.
    I would like to generate 4 more ports for external hard drives.
    If anyone has a video or photo link where I can see how to install that would be fab.
    I have trawled for too many hours now trying to find this info-apologies in advance if it's right under my nose in discussions.
    Cheers

    First of all... do we speak about °Celsius or °Fahrenheit...?
    My northbridge is at 167° F (75° C)... or should I say "was"... of course I installed smcFanControl and boost the minimum fan speed up by +250rpm the heat went down to 127° F (53° C)
    Looks like we have pretty same understanding of building up our work space
    I have two cable slots installed under my Desktop - one for the power cords and one for the data cords. In fact that my desktop is very large an I have 4 MACs, an A2+ Printer, all external devices, an APC and all the network stuff under it in a line. The desktop is mounted to a wall and the space between the wall and the devices are about 1/2m. At the end of the line I use a large fan which pick up the hot air and transport it into the room... to the inlet of the AC... the outlet of it is blowing right at the front of all devices. It works great.... just like a heat pipe... I checked that with a smoke generator.

  • Firewire 800 port doesn't work for cameras but works for Ext drives

    I have a Power PC G5 1.8 running 10.5.8
    I have a 9 pin FW 800 port on the back that does not work for cameras, trying to capture video into Final Cut Pro. But works fine when I hook up an external hard drive to it.
    Does anyone know why that is? It used to work, now it doesn't. Any suggestions?

    Does System Profiler>Hardware>Forewire tell us anything when the Cameras are plugged in FW/800 port?
    Do the Drives have an extra FW/800 port to plug the Camera in?
