Quad stopped mounting firewire devices.

After recognizing my new FW800 hard drive, MOTU 828 and iSight camera, yesterday when I booted up my new Quad G5 stopped mounting these devices and a System Profile showed no firewire ports even present. A simple "disconnect all peripherals and zap the PRAM" fixed it.
Today the same thing happened again so I did the rest again, but nothing happened. I then reset the NVRAM as well -- still nothing.
My relationship with Apple has been love-hate for the last 12 years; right now, after dropping major $$ on a new Quad G5 (against my better judgment because we allllll know that the first round of new computers that Apple puts out is always chock-full of lemons) I am in "hate" mode. 6 Apple computers in 12 years, and all 6 (I'm not kidding) were broken right out of the box.
Can anyone recommend something that I might be missing?

Hey ds,
Thanks for the tips. I actually tried those, along with all of the troubleshooting tips that the phone tech support folks gave me. The only thing that has worked is unplugging the power cord from the CPU, then plugging it back in, and zapping the pRAM on startup -- then the firewire devices will mount.
Because tech support couldn't figure out why that's happening, they've declared it a hardware problem and said that I got a lemon... and I'm off to the Apple Store first thing in the morning to drop off my Quad.
6 lemons out of 6 purchased over 12 years.... ouch.

  • FireWire devices doesn't mount nor are recognized by OSX

    A known issue but with several solucions posted but nothing seems to help me out...
    Something is wrong with the FireWire of my Powerbook G4 667 MHz. External harddrives as soundcards as iPods as anything with a FireWire interface won't mount. However, it seems that the devices are getting electricity, Ipods charge for example. But doesn't appear on the desktop. Nor in the System Profiler. Disk Utility doesn't "see" the drives either. I have been trying with reseting the computer, the VRAM and the VPRAM. Also taken out the battery and left the computer alone for a while. No results. And of course, I have been searching the forums and diskussions like crazy but haven't found a solution.
    Anyone who can give me some leads about what I can do next? A clue in this mystery is that I used a Pocketdrive to move files in between the Mac and a PC. I worked fine for 10 times or so, but then suddenly the Mac didn't mount it. First I thought that it was just that harddrive that had some problems (from the PC, I might haven't emptied the trashbin the last time I disconnected it from the PC) but then I realized that no FireWire deviced worked any longer.
    Thanks in advance

    Hi, jorgengun. Try running the Apple Hardware Test CD that came with your Powerbook, and see whether it reports any problem with your FireWire controller or port. It's possible that your port has gone bad, in which case the timing was probably just coincidental — it's unlikely that anything that happened on the PC could have caused your Powerbook's port to be damaged.
    If you don't have Apple Hardware Test, a TechTool Pro or TechTool Deluxe CD has similar hardware testing abilities. (TTD was supplied by Apple to the purchasers of AppleCare Extended Protection plans, and is not available otherwise as far as I know. TTP is a commercial product.)
    If you don't have any of the above, and all of the devices that no longer work when connected to the port did indeed work in the past, take the Powerbook to the Genius Bar at an Apple Store, or to a local Apple dealership, and have the port tested.
    A bad port would necessitate one of two things: a logic board replacement, or the purchase of a CardBus-slot Firewire card.

  • Anyone able to mount more than 3 firewire devices on their Alum 2.4 imac?

    Hi.
    I can't power up more than 3 firewire devices or my imac kicks everything off. I have 2 Lacie 1T drives piggybacked on the 800 port and then a powered firewire hub plugged into the 400 port. I can have either another firewire external HD OR an external Cd/Dvd recorder plugged into the hub. If I try both (or any combination of 2 firewire devices) - the imac kicks everything off firewire, both on the 800 port and the 400 port. All my devices have their own external power supply. It also doesn't matter how I chain the drives. I can have 3 on the 800 port but then nothing on the 800 port.
    This is a bummer for me. I migrated from a Dual G5 2GB with 4 external HDs and an 2nd external DVD writer attached. My drives are 2 1Ts, a 800 GB and a 400 GB. I do a lot of photography and video editing so I really need the external space. I guess this imac really isn't a "Pro" model but I didn't need any more speed and I wanted to save space and money. And I love the 24" screen. I think Apple should say up-front if there are significant limits to the imac's Firewire capabilities.
    Are any of you you able to attach 4 firewire devices at one time? If so, then I guess my machine is defective and I'll start working with Apple on exchanging it. Please let me know.
    Thanks

    I think you should be able to do much more than 4 - I believe the theoretical maximum is somewhere at 20+ devices (if they are self-powered). I don't have a 24inch but instead a 20 inch but I'm running three HDs and one DVD drive and in fact, all daisy-chained onto one single firewire port on the Mac. Do your external drives have two ports or just one? In the former case, you might want to try skipping the hub and just daisy-chaining them. I've never owned a firewire hub so I don;t know if they can be touchy but you might want to give it a shot.

  • Problem connecting Firewire device and external HD at the same time

    Hi. I'm attempting to record digital audio through a Presonus Firepod A/D interface via a Firewire 400 to 800 cable connected to one of the Firewire 800 ports on a mid-2010 Mac Pro running Snow Leopard.
    The problem is that if I have an external HD connected to one of the other Firewire 800 ports on the computer and powered on at the same time, the connection to the Presonus Firewire device is not recognized by the Mac Pro. Not only that, performance of the Mac Pro is affected adversely and System Profiler is unable to list any Firewire devices. If I turn the external HD off, the Presonus device is recognized and listed in System Profiler and the machine runs fine. I'm able to connect two external hard drives via separate Firewire 800 ports on the Mac Pro and both drives mount w/ no problem. It's only when I try to connect one of the external HDs and the Presonus audio device at the same time that the problem occurs.
    I used this same arrangement on a PowerMac G5 running Tiger w/ no problems whatsoever. If the 400 to 800 cable is bad, I would think it wouldn't work at all, but it does when only the Presonus Firepod is connected and powered on. Any ideas?

    Have done more research and apparently this is not an uncommon problem: overloading the Firewire bus when connecting an audio device along with an additional device like an external hard drive. As I understand it now, audio signal is a bandwidth hog and the solution is to get a Firewire PCIe card which will have its own independent Firewire bus and which I'll use exclusively for my audio device.

  • External drive enclosure, USB 2 mounts, firewire invisible!

    I have a venus ds3 external enclosure with a 300GB 7200rpm WD hard drive inside it. The enclosure works fine with windows and usb2, and it is also detected and mounted on usb2 on my mini (1.25ghz ppc mini). However, nothing happens when I try to use the firewire connection on the mini. In system profiler, I see:
    FireWire Device Tree
    FireWire Bus
    Unknown Device
    It is an oxford fw911 chipset, and I did run the updater to FW911V4_00_0000Release.bin, but still no firewire action. The updater saw the enclosure via firewire on my mac, but os x will not see the drive itself.
    Am I doomed to using usb2? Would it still be possible to boot from this drive on usb2 instead of firewire?
    mac mini   Mac OS X (10.4.7)   upgraded to 512MB ram

    problem is
    you cannot use 300 gigs as fire wire on any mac mini
    the max you can use is only 200 gigs before mac os x
    no longer recongnizes the drive
    so you need a 200 gig hard drive sorry
    Is there some documentation that you could cite on the 200gb barrier?
    I'm also interested if it's a ppc-mini only problem or if it affects other systems as well.
    I have a 250gig firewire drive on my wife's intel mac mini
    and it works fine. Even if it only regognized on 200gig and
    I didn't notice, it mounted and worked.
    I now have it partitioned into 2 samller volumes. So, if it's
    a problem on the PPC mac, then he should be able to
    partition the drive and make it work.
    I just now tried partitioning it again via usb, and made two 137gb partitions (or whatever odd number it came out to be), and it was still not recognized when I switched over to firewire.
    If it turns out that john was right, and nothing over 200gb will work, can I still get some use out of the drive? Can I install applications on it or move the swap files over to it?

  • Using Firewire devices results in desktop stuttering

    Firewire traffic is causing desktop performance to decline. On my Mac Mini (late 2009, 4 GB RAM) even slow amounts of firewire traffic is causing bad spaces performance (stuttering while moving from space to space) and jerky window movement. I have tested this with several cables and 2 different firewire devices. Device 1, a Canon HDV camcorder, is bringing the window movement to stutter when imovie is detecting the connection and showing the import screen (no transfer initiated, not even playback). Device 2, a Western Digital My Book Studio with FW800 ports, is making the desktop jerky even if it is only playing a mp3 file.
    Notes:
    Spotlight was disabled on the mentioned fw800 hdd. Disk activity monitor shows normal operation, very low cpu workload. The system log also does not show any suspicious messages.
    USB devices like harddisks do not trigger this behaviour. The mentioned fw800 disk also has an USB port. Connecting the device using USB does not slow down desktop performance, even when transfering large files.

    Thanks for you suggestions. I tried them out (and some more).
    Here are the results:
    You can test to see if the Virtual Memory system is getting overworked by running Utilities Activity >Monitor, click on the System Memory tab and look at PageOuts and PageIns.
    I kept an eye on the virtuel memory for a while now. Seems to be fine, even after hours of my usual working procedure there are virtually no page outs.
    But if your ratio is good (10% or less), then I'm would suspect instead that you need to re-install a >full combo update of the latest version of OSX.
    I reinstallad the 10.6.4 Combo Update. No difference.
    Then I installed a fresh copy of OSX on the firewire drive. Running an unpatched OS from the drive is not bad in regards of system response time (actually it's pretty good). But the desktop jerkyness is present all the time.
    Then (after switching back to my internal drive again) I stopped keeping an eye on window movement etc. and tried out some games. The results: There is a major difference in performance when the fw drive is working in the background in contrast to an usb2 drive (or even the same fw drive attached using usb). When I am playing the game (in this case it was an opengl port of Doom) there is virtually no performance penalty when I am playing the game while transfering a huge file to an usb2 drive in the background. But when I am transfering a file to the FW drive, there is huge drop in frames per second (roughly 25 - 30 %).
    I am wondering if this has anything to with fact that firewire is using dma access to the system memory (in contrast to usb) an there is some sort of congestion on the memory bus. Especially since my issues are linked to gpu performance and the 9400M in the Mini uses shared memory.

  • Thunderbolt to firewire adaptor does not work when daisy chaining firewire devices

    Hi,
    I just purchased the Thunderbolt to firewire adaptor for my new late 2012 iMac.
    It works when connecting a single firewire device, but when I daisy chain another drive, the first drive disconnects and nothing mounts.
    I am trying a Hitachi G-Raid and a couple of WD My Studio II hard drives. They all work when connected directly to the adaptor, but not when more than one drive if daisy chained with firewire.
    Has anyone got firewire daisy-chaining working with a thunderbolt adaptor? (just to clarify I am not refering to thunderbolt daisy chaining, as the adaptor is an end-of-chain thunderbolt device).
    Thanks

    Yikes, that's sad to hear.
    I can't test it, no TB here, but are all these drives self AC powered, ie. no bus powered drives?

  • Missing firewire devices

    For some reason my G5 dual 1.8 has stopped recognizing my sony firewire devices in FCP 5.0.4 (PD150 camera, DSR20 Deck, Z1U, etc.). A friend has suggested that I need to reinstall my system (10.4.6).
    Any other (less time consuming) thoughts?

  • Mounting Firewire drives

    If I have two external Firewire drives connected in series, one to another, and eject the first drive, will the second drive stay mounted and show on the desktop?

    This is the FW info, http://support.apple.com/kb/HT2952
    Repeater function
    The built-in repeater functionality on Apple computers with two or more ports allows FireWire data to pass between external devices through the computer. This repeater functionality is available even when the computer is in sleep mode or turned off, provided that it is connected to AC power. On a portable computer running on battery, in sleep mode, or powered off, the repeater functionality is provided if at least one FireWire device supplies power to the computer via the FireWire cable.

  • Kernal panic - log mentions firewire repeatedly but no firewire device

    Hi Guys,
    Any help appreciated with this. Firstly although my profile states leopard+ macpro this relates to a G5 running 10.4.11. We had a kernel panic earlier on a machine that has seemed buggy over the last few days (in spite of running Applejack). Weirdly the log mentions firewire repeatedly in spite of no device being mounted (there is a drive plugged in but not mounted + powered off). Ran verify disk + repaired permissions (nothing needed repairing) afterwards. Any ideas? Thank you.

    If you suspect RAM,look at this link: *Testing RAM* @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.

  • The FIX for FireWire Devices not being found.

    If you have FireWire devices connected to your iMac that are no longer being recognized, this post is for you.
    1. Power off your iMac
    2. Unplug all USB and Firewire cables from the iMac.
    3. Unplug the iMac from the main power.
    4. Wait 4 minutes
    5. Reconnect and power on.
    6. Devices will be found as you'd normally expect.
    Somehow, four minutes without any kind of power resets the Firewire interface so that it will work again.

    1. Power off your iMac
    2. Unplug all USB and Firewire cables from the iMac.
    3. Unplug the iMac from the main power.
    4. Wait 4 minutes
    5. Reconnect and power on.
    6. Devices will be found as you'd normally expect.
    On step five, you say 'reconnect and power on'. Does this mean I should turn on my external device and connect before I turn the iMac on?
    As for my ports being blown, I don't think that's the problem for me. My iPod easily mounts on firewire. And this device mounts on my other machines that use 10.3 panther.
    Sorry if it sounds like I'm trying to hyjack this topic, it sounds like you've got a good method and I want to utilize it properly!
    Thanks,

    On "About this Mac > More info" page, my Dell Axim X51v Pocket PC is listed as a USB device. I'm having problems using the Parallel Desktop running Windows XP to sync to the Axim because Parallel reports that "USB device you are trying to connect to the virtual machine is being sed by another process." Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually."
    AFAIK, nothing on my Mac is using the Axim right now, I have even disabled "Missing sync for Windows Mobile" and stopped it from loading so it must be the Mac OS not releasing the USB link so my Windows XP within Parallel is not able to pick up the Axim right now.
    In Windows, there's a "Remove Hardware" option. But I can't find this on OSX after digging around for half an hour, I think I'll get much better advice here, so I really look forward to your help.

    You wrote: "But I don't see the device as "mounted" on the desktop, or in Finder."1. In the Finder > Preferences > General tab, is the "Show on Desktop" option for CDs, DVDs, and iPods selected? If not, select that option and see if it appears on the desktop.
    2. Is it shown in the Finder Siderbar?
    Good luck!

  • In system profiler it says "unable to list firewire devices"

    I have been trying to figure out for days why when I hook up my camcorder with a firewire that all that comes up on my screen is the isight camera and not my camcorder. I have tried everything. I finally went into the system profiler and checked my firewire bus and it said it was unable to list firewire devices. My computer is only a few weeks old. Do I need to take it in or is this something I can fix?

    Any word on a solution? I also have this problem. My Panasonic DVX100AP works great with my MacBook Pro (10.4) but when I try to use it with the same version of Final Cut Studio (5.1) on my new iMac with Leopard, it's not recognized at all. It wouldn't recognize in iMovie 08 either. I then checked the system profiler and found the "Warning: Unable to list FireWire devices." message.
    I called AppleCare and they had me try and connect my MBPro via firewire for target disk mode. Sure enough, the MBPro's hard drive mounted fine on my new iMac via firewire. So the firewire port is fine.
    The rep suggested that I contact Panasonic as she believes it's an operating system issue and that Panasonic needs to offer some sort of software solution (driver?) to fix this. I've contacted Panasonic and am waiting to hear back from them.
    If you have any tips, please let us know.

  • If your Mac suddenly looses Firewire devices, here's one cure...

    Since we FCP people use a lot of external Firewire drives, this might be useful.
    If your Mac suddenly looses Firewire devices, try this. (I got this from LukeA on the iLounge forums.)
    Shut off your Mac for at least 10 minutes. Then reset the P-RAM (whatever that is) by holding these keys on startup: Cmd + Opt + P + R - until the Mac chimes a few times.
    My Mac Mini suddenly stopped recognizing any external Firewire drives. I thought the port had probably blown on the computer, and was about to buy a new iMac, but I tried this as a last resort. It worked!
    Now I don't get my new iMac! ****!

    Just so you'll know, Apple has a ton of articles and how-to's right on this website (just click the Support link above and do a search). Other common Firewire problems can also be addressed by resetting the PMU (Power Management Unit) button: http://search.info.apple.com/?search=Go&lr=lang_en&kword=&type=&newstype=&q=pmu

  • Way to mount FireWire external HDs so I can access remotely?

    This is either not possible, or I am totally looking in the wrong place. I have three FireWire external HDs that are chained, then plugged into an iMac G4 running 10.4.11, then mounted to the desktop. File sharing is on, along with Remote Access, Remote Login, etc. in the Control Panel.
    I am trying to login remotely (through ftp, afp) using a MacBook Pro running 10.5 to view/copy files from the HDs, but all I am able to login to is the Home Folder of the username/password I put in - the HDs don't show up. I've tried various things, such as Virtual Folders, trying to input the path to the HDs in the address string - all to no avail.
    Is there a way to mount FireWire drives so that a remote user can access them?

    If you're external HDs are mounted as a local volume, that should up under Devices in the Finder window. Does it? If so, then in Preferences->Sharing->File Sharing, you should be able to add that volume as a Shared Folder. Is that what is giving you trouble? (I don't have an external HD, so can't test it).
    Once you've shared that out, you should be able to connect to it via afp://, nfs://, or smb://...
