Firewire Port Issue

Hi everyone. I'm a mac person in training and have a question about a machine that I am working on. I had a customer that had a bad front panel board on their G5. Everytime I plugged a usb or firewire device into them nothing would happen. I replaced the front panel board and tested the ports before returning the system back to the user. After I reinstalled the machine onsite, I plugged the users Firewire drive into the front panel board and attempted an Option Boot but only their internal drive would show.
I then unplugged the customers cinema display firewire plug from the back of the system, plugged their firewire drive into the back port and tried Option boot again. This time the drive was found. Out of kicks I tried it again in the front port and it worked there. As soon as I plugged the Cinema displays plug back into the back firewire port, option boot could not find the firewire drive again.
Any suggestions?

Yup. Happens all of the time.
The FireWire hub located in the monitor is bad. If the monitor is under warranty it can be fixed that way.
I am not a fan of combined devices, as when something like this happens you lose the use of the monitor while the 4 dollar hub is repaired.

USB/FireWire Ports Issue

So before I go into the apple store and ask for this computer to be repaired/replaced, I would like to see if anyone knows if something can be done about this issue I have pinpointed..
Basically when I have more than a few USB/FireWire ports connected, one or more of the devices does not function properly. This has happened with two external hard drives - which should have no problem being connected simultaneously.. When I try to eject one of them, I receive a message stating that it cannot be ejected because one or more programs may be using it.. although all programs are closed, causing me to have to force eject..
Also, I plug in one drive and open the other in finder to back it up, and all of the folders in the drive are suddenly empty.. nothing inside. I go to Get Info.. Zero KB.. I try ejecting, but receive the same message, so I force eject, plug it back in, and wala, all the files are back in the right place..
This has also happened in the past when my cinema display and a printer were plugged in simultaneously.. the computer won't detect the USB of the cinema display -- which only means that the speakers of the display won't work + no brightness control from the keyboard.. so i let it slide.. but now with this external hard drive issue, i need to solve the problem..
Thank you for reading..

Same here. Since a few weeks, my MacPro ejects USB HDD's as soon as I write or read data on it.
(no I haven't installed something new at this time and all HUB's and HDD's have their own power supply, and yes they have been exchanged, so its not a broken cable or so !!!!!!!!)
After a reset of the NVRAM and PRAM its better for an hour or so, then starts to eject again. I've seen a lot of communities with exact the same question, but never a solution for it. There is also nothing in the support tab of apple.
Hope someone here can help me out or due to the fact that this is a AplleSupportCommunity, a Apple-Employee may starts to do his job and help this huge amount (I guess there are hundrets or tousand) of mac-user with exact the same problem....
btw: don't agree with MACATTACK2010 that this is a hardware problem, cause there are a lot of people in the
net that ask the same question with brandnew Hardware. I think it's an OS or an Update Bug, or may both.

How to fix a lack of enough firewire ports issue?

I am using garageband with an Alesis iO14 audio interface. Just bought a Liquid Mix 16 with a firewire connector. Am having trouble with the Liquid Mix after installation. The mfr. says I should not daisy chain the two. They recommend a firewire expansion card. Is this even possible with the mini? any advice on how I can fix this? I really want to use this Liquid Mix. Thanks.

You are out of luck. This is so annoying. I just don't understand why Apple can not give most of their machines not only two firewire ports, but two independent busses as well. This is not a luxury in my opinion. The only machine in their entire product lineup what allows for expansion of firewire busses/ports is the giant Mac Pro. Mac computers are used in so darn many professional industries that depend on not only fast harddrive interfaces, but interfaces of various kinds that need a dedicated high speed buss. Pro machines should feature pro inputs and outputs. They've even taken the ExpressCard interface away from all but one laptop. What's next? Maybe they should just remove the USB ports too and assume that we all love wireless keyboard/mice/card readers/printers...it's insanity.
You are supposed to be able to daisy chain an enormous amount of firewire devices, but in reality, that just does not work all the time. I too had all kinds of problems chaining a MOTU 828mkII and one single harddrive on one FW buss. No matter of changing order of hooking them up, to which one to turn on first had any effect. They both wanted more than the single buss could give.
I'd return the LiquidMix if you can...the only mac in the current line that I can honestly call Pro is the Mac Pro tower. The others just don't have pro or even semi-pro in/out anymore.
It's almost like Apple really likes to not give us pro's what we really need. Close, but not quite. Imagine a macbook pro with two firewire busses? WOW! The audio and video crowd would go crazy for them. Imagine they also put back expresscard slots on all laptops in the Pro line? You could have 3 separate input busses for harddrives, cameras, audio interfaces, etc. Now that would be pro.

How can I tell if my firewire port is faulty?

I recently cannot import video from my canon elura 100 which connects using a 4-6pin firewire cable. I thought maybe it was the cable so I grabbed my brother's black macbook and it seems to import fine, it still isn't 100% smooth like I think it should be but when I plugged the camera back into my black macbook, the video that was being imported just kept freezing and it seemed warped. I tried this process a few times and kept getting the same results. I feel as though I may have a firewire port issue. How could I check on my own. I know that when I use my firewire 410, I have no problems so I don't know what could be wrong. Any help?

Did any of your problems start with Snow Leopard, is your brother's machine running the same version of SL.
Over in the audio forum there are those having some problems with their firewire interfaces. (glitches, static...etc)

Issue Using both Firewire Ports on 24" iMac

I just got a new 24" iMac with the 3.06 processor. I intend to use it with Pro Tools and other music making software. I have an audio interface that is firewire only and an external hard drive (where I store my audio files) that is both firewire and USB. The problem is that I when I use both firewire ports (800 and 400) at the same time, my Pro Tools starts acting up. And I found one post stating that this was a known issue with the 24". But that was back in May and I thought it would have been resolved by now. Anyway, when I use the USB port on my hard drive instead of the firewire, everything works. Also, on my 17" iMac PPC G5 everything works just fine on there, including using both firewire ports a the same time. Finally, I've got the latest updates on all devices involved. Has anyone experienced this problem or have any knowledge of it? Thanks in advance.

I've got a similar problem. I've got a WD external drive connected via FW800 and an Mbox pro 2 audio interface connected via FW400 to my 24" mid 2007 iMac. They both power on (the mbox gets it's power from the iMac) and are recognised by the iMac. However, the WD drive seems to take dominance at some point during start up. The reason I know this is because I was watching the LED on the Mbox light up as I sent it signal from the guitar and then it suddenly stopped lighting up. I tried daisy chaining the mbox to the WD but outcome was the same. Then tried chaining the WD drive to the Mbox (this meant the WD drive was now down to FW400 speed). It worked!!!.............until the next time I started up the computer. The WD drive wasn't recognised by the iMac.
I'm not impressed with the iMac's inability to deal with devices from both it's ports. Why put them on the machine if they can't handle it?
I bought the WD drive to work at FW800 speed and don't want to have to submit to USB 2.0 if I can help it.
Any suggestions welcome.
Thanks

Firewire ports causing "initilaized drive" issues?

So this is now the second time this has happened to me, and since it was with a 4 day old drive I'm a little concerned (especially as it was used to recover files from ANOTHER drive that got erased...)
i just plugging in my new Western Digital 1tb Mybook Studio external drive using the FW800 and got a message saying "unable to recognize drive, initialize, cancel" etc.
Because it was new, i just hit cancel (glad I did...)
Plugged it in again, and all was fine. This had happened before a few months back with another drive only using the FW400 port.
Is there something WRONG with my Firewire ports that could be causing this? I've NEVER had an issue with USB (but these are scratch discs for video so they need to be FW). Im really concerned that this could fry my drive... which would be bad. cause i have a lot of important data on these suckers.
any ideas?

My Firewire port is not working: Is that a Hardware or Software issue? any suggestions?

Greetings Everybody,
I bought this Imac to use it only with audio applications and now I can't use my UAD -2 Duo Satellite because MAC OS tells me that "
No FireWire ports were found" Does any know how to deal with this problem?
Thanks in advance

Why would the Firewire Port and/or External DVD-RW suddenly not work?

Hi, it's me again. I swear, I must be destined to just use Windows machines...
Anyways, I have a used/refurbished iBook G3 500MHz 320MB RAM Dual USB (1 Firewire)laptop running OS 10.2.8 that I bought a few months ago. I went and purchased an external Firewire/USB 2.0 DVD-RW drive as I only had a CD-ROM drive on my machine and I wanted the option to burn CD's or watch/read data from DVD's (I know that with my slow processor writing DVD's -other than data- would be a stretch and have other machines to do that with anyways so it wasn't a concern really). I received it and installed it, also installed the free version of Toast that came with it, and the drive worked fine. I have not needed to use the drive since then and have not used the laptop much at all since then really, but I do need to say that I did end up adding a new user account, though I can't remember if I changed the original Admin account and then still have the one I created myself when I first started the laptop after I bought it (had a fresh install of Jaguar on it, but I have no disk to re-install with if needed) or if I created a separate (new) account and ended up deleting the Original Admin accout (I know in Windows, you cannot delete the original Admin account but I do not know if that is the same for OSX or not). I did this as I wanted a master Admin account that I just wouldn't really use and then wanted the other as my main account (and use it to connect to my home windows network) and for some reason it would not let me put a check in the box to allow that account to do so (from either Apple or my user accounts) and so I know that my main user account now is set up to allow it (was it the old Apple user account or a new one, I can't remember- sorry).
Ok, so that is the back story to my problem, which happens to be this:
I just bought a new chip of RAM (512MB to make it a machine with 576MB RAM total) and as I had been looking at getting OSX Tiger (but didn't want to do it without the extra ram and had been considering Panther instead as well), I thought it was necessary if I wanted to not bog down my machine. I bought the Install Disks on DVD for Panther, as well as an upgrade disk (DVD again) for Tiger, therefore letting me use the External Firewire DVD-RW to install Panther, and if I liked I could go ahead and upgrade to Tiger (and if I didn't like it too much, or it slowed things down too much etc, then I could always go back to panther and have both available for future options). The extra RAM coming in handy here definitely.
So I was going to install the RAM today, and decided to go ahead and test out the External DVD to make sure it could boot from it (before making any changes to my system) and then go and install the RAM, and after that, install Panther to start... But I plugged all the cords and cables in, used my laptop with AC power even, and I could not get the External to show up at all... (kinda like the very current post right below mine but for the G4- it worked before, but now the firewire External just does not show up).
I only have USB 1.1 on this laptop obviously, and I don't even know if you could do a boot from an external with USB 2.0 if my laptop had it (the DVD player does). I was recommended to boot with an external firewire DVD or firewire to another machine with DVD capabilities to do the install. So my problem right now is getting slightly bigger, as of course, I can't seem to momentarily find the stuff that came with the External (spare USB cable to check and see if the laptop will recognize it at least with that and to show it is the firewire that is not working properly, or the disk that I used to install it -might have been only used to install Toast free version if it didn't need any drivers, but I don't know where that or the instructions for installation sheet currently is -- I am looking for it, but I have switched bedrooms just last week and I also seem to be missing a few other Windows laptop disks as well so there is a good chance that they are all together, I just need to figure out where, heh.)
I am waiting currently before installing the memory, though if I don't get the External working tonight, I may go ahead and do it first as at least I will have more memory on my laptop then, until I can get other stuff functioning and be able to do the Panther install.
But my main question is, is there something that would cause an installed external to suddenly not show up in OSX? Since I hadn't used it since that one day, and it was unplugged from the laptop itself, would that end up doing it, or more likely, the changing of the user accounts (though I have been trying to test it with different types of media and through both of my user account (which are both "admin" ones), though I do still have one of those being an account that was on there when the External DVD was first installed, so it really shouldn't have done this at all (one would think). So how big of a chance is it that the firewire has somehow gone dead and this is the main culprit to my wasting the past 4 hours on this???
I am currently scavenging around for an extra USB cable to try and test the External that way and will post the results when I can... I love the look and idea of macs, now I have a mac and want to upgrade it even, but why is it that whenever I attempt to use it after having not used it for a bit (and try to make the iBook feel better by using it more as I am sure it feels sad and alone sitting on the shelf while my Windows Laptop gets more attention), or try to fix it when it can be made better (and therefore used more often), the mac (all macs really), just seem to get all pissy and cause problems and make me spend hours upon hours trying to get things to work again??? You have to admit it, I am "mac cursed"... sigh I can program in 4 or 5 computer languages and am very advanced at many tech things (the ones I am not as good at I am still usually Average or Medium skilled) so it makes me wonder why I have so many tech problems with Macs when they are supposed to be the "easy" OS to use...

Actually, I think I have it all working now. After going back to the Plextor Website, I found out that the switch between the USB and 1394 ports only gets activated (switched over to the other) with you turn the device off first, move the switch and then turn it back on. I was sure that I had done this with the ibook, but maybe not as when I went back and did it with first the USB and then the Firewire cables, it did work. I definitely knew that I had not done this with the Windows laptop, the reason it would not have the USB work for me on it.
but back to the iBook, I was confused as it was only showing up as a DVD-ROM (which I guess is what they do until you actually open up the burning software to then be able to burn to it), and it also had the wrong Model #, which after more research, showed that it was the Internal DVD drive model version (PX-708A) compared to the actual model version (PX-708UF) which is the USB/Firewire (External) model. The firmware was really out of date as well (from June 2004 I think, v1.06) and they had v1.12 from Spet/Oct 2006 available so I went to get that (which was a hassle). They had nice easy Windows self extractor/installer packs, and then the BIN files for use for all systems (Sun OS/ Mac OSX/ Mac OS/ Linux etc as well as usable for Windows), and those needed a special Firmware Updater Application which was OS specific. Only I had the hardest time trying to get the OSX one as it would send me to a FTP site and not give me any clues as to which file(s) I needed to get and the Mac OS version was just for older 9.2 or below versions and didn't want to install under the OS Classic mode.
I ended up using my windows computer which made it easier to view with the FTP stuff as I have FireFTP in Firefox, and downloaded the files I thought I needed (to test out), and then realized my silliness, and just downloaded (as well) the Windows Auto Extractor/Installer as the Firmware is the same for all OS's, just the way to install/update it was different... So I hooked the DVD drive to my PC and updated the firmware, checked it out on here before moving it back to the ibook, where I checked that it still worked and had the new update version showing, which it did, and now I have my fully working and newly updated drive ready for the OSX installations... I had attempted to update my Jaguar system as well while online, but it had no new updates available (I guess those were all mostly Tiger updates that were just recently released).
I am now off to install my additional RAM, and after checking that it all shows up correctly, I will go ahead and do the Panther Install (and test it out and see if I like it or not).
For anyone that currently uses Panther on any mac, are there still any major problems I should know about before hand, or know about things that they have mostly fixed (like the issues with Firewire ports and External Drives that they had around the time Panther was first released for example)???
Thanks to all that helped... I now know to attempt an "eject" of any external HD (which I do have one that I will setup to use after I get Panther on the ibook) or CD/DVD drive instead of just unplugging the USB/Firewire cable.

Firewire port not working Mac Mini (G4 1.25ghz)

Hi,
The firewire port isn't working on my mac mini, I've tried several devices, but none are connecting. I was wondering if anyone else was having this issue and possibly a solution. The only software installed on the computer since the firewire worked last was Apple updates, so maybe other mini's lost firewire somewhere along the way.
Thanks, and Thanks

This worked from Smokerz in the Power Mac G4 forum:
1. Shut-down your Mac, and unplug the power cord
2. Turn the power off on your external FireWire devices
3. Unplug the FireWire devices from the Mac
4. Wait for 5 min.
5. Plug the power cord to your Mac only
6. For PPC Macs: Restart the Mac while holding the Option-Apple-O-F, and keep holding until you get the ">" prompt, then release the keys
7. At the ">" prompt type:
reset-nvram and hit the Return key
set-defaults and hit the Return key
reset-all and hit the Return key
the last command will restart your mac
8. Shut down your Mac
9. Connect all your FireWire devices to the Mac and turn them on
10. Restart your Mac.
Works fine now thanks Smokerz!!!!!
also repaired permission and reset PRAM, nothing worked until I did this.

How How can i install Mountain Lion with faulty firewire ports??

Basically the firewire ports are fried on my MBP 3.1 (2007). My mac used to take hang on blue screen and take 10 mins to boot but I solved this problem by installing an ssd and deleting the following kext file...
/System/Library/Extensions/IOFireWireFamily.kext
My MBP now boots in under 20 seconds so if anybody is having the same issue then there is the resolotion..
Anyway these are the steps I have taken but failed to properly install ML.
Dowloaded Mountain Lion at least 3 times from the App store to make sure the download wasn't corrupted.
I even tried making a Lion Bootdisk so I can install Mountain Lion on a USB drive (Install ESD.dmg).
I have even tried installing Lion first thinking I would take it one version at a time but gets stuck on boot screen too.
I even changed my hard drive to a new blank SSD drive to see any difference.
Each time I install Mountain Lion or Lion, everything is good until the installer has to restart the laptop.
Laptop gets stuck at the grey boot screen with the Apple logo and the loading circle. Nothing ever happens after.
I always had to use/boot to the Snow Leopard CD so I can restart the laptop back to the Snow Leopard OS and then update to 10.6.8.
I am guessing it is the ML dmg reinstalling the above file ( /System/Library/Extensions/IOFireWireFamily.kext ) which is leading to the same issue because of the faulty firewire ports.
Is there anyway I can resolve this because its doing my head in and Snow Leopard is old and doesnt support newer software that I would like to use.
Any help would be kindly appreciated. Thanks

Just some thoughts.
I presume you already partitioned the new SSD drive as GUID?
Is there anything on the new drive at all yet, or anything that isn't already backed up? If not, you could try erasing the drive and then installing OS X from the bootable flash drive installer you made.
Ive tried that and yes it is GUID. Im going to get grey hairs soon and Im not even 30 lol .... yet
I am not going to buy a new logic board as its just not logical (sorry for the pun) I got the mac for free and I want to spend as little money as possible. Im running out of ideas though

Problem importing video from a DV camera into the new imovie 10.0? I have a Sony DCR TRV17 connected via Firewire port that worked in 9.0.9 but not under 10.0...

I have a Sony DCR TRV17 that I used to pass through VCR tape video via Firewire port to my Mac Pro under Imovie 9.0.9 without an issue. Now under Imovie 10.0 the video shows in the import window, I can start recording yet when I stop recording the recorded clips do not show up anywhere. The movie file I'm creating still indicates that I still need to import video. Anyone having similar problems?

Hey Dave,
I had this issue only once before but was lucky enought to find it was a specific event causing the import to freeze. It took me some time to isolate the problem though. I would recommend letting it sit there for some time before you try any troubleshooting. Larger libraries can take long periods of time to update.
This is a good thread for this issue. I would first try removing the iMovie.plist as elikness mentions.
1. Open Finder
2. Click on "Go" in the menu bar.
3. Click on Go To Folder on the dropdown menu.
4. Type "~/Library/Preferences/" in the text field and click Go.
5. Find the com.apple.iMovie(some number).plist file and move it to Trash.
Quit and relaunch iMovie to see if this took care of the issue before attempting the next step. If you're still having an issue then you can try what I needed to do which is isolating the problem event.
1. Open Finder.
2. Go to the Movies folder. You should see iMovie Events here.
If you have a larger event library I'd recommend renaming the iMovie Events folder to say, "iMovie Events COPY". Then create a new empty folder named “iMovie Events”. When you launch iMovie 9.0.9 all events will be missing at this point. Quit iMovie if it is open. Then you can either drag each event from iMovie Events COPY to iMovie Events or you can select and drag several at a time. Each time you drag an event folder back into the new iMovie Events folder launch iMovie 9.0.9 to see if you are having the same issue. Wash and repeat until either you have found the problem event or you have imported all events.
If you find the problem event you can reimport the clip from iMovie 9.0.9 by going to File > Import > Movies and navigating to that events iMovie Original Movies folder to find the clip.
Hope this helps!

Leopard USB and Firewire Ports

With leopard 10.5.1 loaded, I frequently get the grey screen of death (kernal panic) if I have a USB device plugged in (other than the mouse and keyboard). I have Pantones's Huey (Screen calibrator) attached to the USB on my keyboard. After reading many forum issues about USB devices jamming up Leopard, I decided to unplug the Huey sensor... no more problems! Also I have a 500 GB WD My Book Studio external HD plugged in the back Firewire 800 Port, it works well. Plug a Digital Camcorder in the front Firewire port.. not only does my camcorder not mount, but my machine spits out the external HD and gives me an error message about improper device removal. Please release 10.5.2 and include fixes for these external device issues!
PS on a Tiger OS I have had zero conflict with these periferals

When I first installed Leopard I got an "install media is corrupt" message about the Leopard Install disk right from the start. My first thought was the hard drive. So I purchased and overnighted an new 500 GB internal hard drive to back up the main hard drive. I erased and reformatted my main hard drive to install Leopard on. Same problem. I tried to install on the new 500 GB HD no luck. I also installed 2 GB dimms at the time. Turns out the dimms weren't agreeing with leopard. I returned the dimms for new only to have the same "corrupt media" message. Crucial explained that the memory should be largest dimms toward the processor (slots 1 & 2) and so on. I put all my memory back the way it was and everything seemed normal. I installed Leopard successfully. I started to get frequent Kernal Panics with everyday use (I do graphic design). I checked the forums and kept reading about problems associated with USB and this or that program. I unplugged my Huey (used for screen color correction) and Wha-lah. No more Kernal Panics.
But, now my digital camera and my Dazzle 6in1 media reader do not mount and/or hang up my machine with a kernal panics. When I tried to boot from and use Leopards disk utility I got the "media corrupt" message again.
I just hope 10.5.2 addresses the Leopard to hardware/USB/Firewire issues.

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

Imac G5 won't start with Isight plugged into the firewire port.

I went to turn on my Imac today and it wouldn't start. After checking all the usual culprits (power strip, outlet and power chord) which were not the problem, I proceeded by unplugging all the external devices from the back ports. After unplugging the computer for a few seconds and plugging it back in (which I read resets any power issues), it turned back on. I plugged my Isight camera back in and turned it on and the computer suddenly shut off. I reproduced this quite a few times and it did the same thing. It won't even turn on if any device is plugged into the firewire port. Does anyone have a clue of what this conflict could be or experienced anything similar.
I would greatly appreciate any input.
Thanks in advance,
Daniel

Welcome to Discussions - try resetting your PRAM, if that doesn't work, I'm afraid there is something wrong with your logic board, where the firewire bus is located. The best thing to do would be to take it in for servicing.

I have a mid 2007 iMac w/ mac OS X Lion 10.7.5. My time machine (LaCie) is not responding through firewire port (since day one). Did an update mess this up?

I have just recently realized that my time machine has not backed up in a couple of weeks. I am using a LaCie external hard drive that I purchased with the iMac and has been plugged into the firewire port since day one. When I try to establish a connection it only gives me airport utility. When I look through network connections it shows that my fire wire is not connected or at least it doesn't find anything connected.
I have also been getting a start up disk message off and on that I need to close applications due to no more memory? (or something similar to that).
Just curious what might have changed. Did an update re configure something? Are these two issues connected?
I have always loved my Mac for the fact that it just always worked. I'm not super savvy with computers and the settings so I'm not the kind that just goes in to tweek things. This is the first real issue that I have had with it. I would think that it was the fact that I upgraded to lion but I did that quite a while ago.

Hello,
It isn't the fw in Network you want o use or look at, that's for something completely different.
My first suspect is the Power Adapter on the LaCie has gone.
At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware>Firewire, what is listed there?
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.
