Non-functioning Firewire ports

Help...!
I have a MacPro hooked up to an Apple 23in display. With the display's multi-plug attached to the rear FireWire port, the front FireWire port doesn't work, nor to the ports on the display. The USB ports work perfectly.
The FW ports are obviously connected as they draw enough power to charge my ageing scroll-wheel iPod, but the connection isn't strong enough to mount anything.
If I remove the display's FireWire plug from the back of the MacPro, the front port comes back to life. It's workable, obviously, but does anyone know why I'm having problems?
MacPro dual 2.66   Mac OS X (10.4.9)  

Thanks for the reply. It's not just the iPod, a Formac 250GB FireWire drive doesn't mount either. Spent an hour or so doing the five Rs with the iPod before I realised it worked fine on my old iMac.
I've unplugged the display's FW plug and I can use both the MacPro's FW400 ports at the same time - I'm just not too chuffed with the front one not working with the display attached. Perhaps the fault lies with the display rather than the MacPro?

  • DV7-22xx Notebook, Non-Functioning USB Ports

    Things I've tried:
    Plugging in known working devices (ie: mouse, keyboard, etc)
    Uninstalling and then reinstalling the root hub devices from the device manager
    Updating the BIOS to the latest version
    Eating a sandwich and thinking really hard about a solution
    Morally questionable language
    I'm running Win 7 64bit.  This has always been an issue but I've never needed the ports on the right side of my laptop.  The two on the left work correctly for the past year.  What else could I try?
    Thanks!

    Sounds like only option is to return it, especially if the drive works on other USB 3 ports.

  • K8N Neo4 (MS-7125) USB, Mic, S/P Out, and LAN ports all non-functional

    I'm hoping someone can give me a hand with this.  I'm not a novice when it comes to motherboards but this particular board is making me feel like it.
    Ok, I've got a K8N-Neo4 MS-7125 model.  Athlon64 3700.  I have all the current drivers and ran the liveupdate to make sure. 
    The LAN port will light up, but the Device manager will not recognize it, nor will the LAN utility.
    The board has 4 USB ports.  The top two are non-functional, the bottom two work.
    The S\P OUT port has never worked, nor do I know how to engage it or find it on the device manager
    The microphone....this one is fun.  Its like the microphone is stuck in a feedback loop.  Whatever comes through my speakers, is heard on the other end by other users.  I am not heard at all, although I can hear myself through my OWN speakers.  Even with the mic unplugged, people still can hear my speakers.  Imagine having your speakers plugged into the mic jack.  The only way to kill the feedback is to actually go into the sound manager and mute the whole mic system. 
    I can live without the LAN and USB ports, but it would be a HUGE help if someone can help me with the mic and S\P ports!!
    Thanks!!!

    As for the flavor of the NEO4 the only other numbers I know of, is on the board it says N1996 right below the processor.  Is that what you need?  Its a PCB V.3 board nvidia Nforce4.

    Logitech Mic/Headset combo
    This particular case allows for hookups for headphones and mic in the front.  The case has jumpers in the back that allow you to gain access from the front (but you probably already know that).  I've always used the front MIC/Headset jack, and I have a splitter in the back for the headphones and that jumper.  In trying to resolve the issue, I tried every jack with the microphone (even the ones that I know are labeled as speakers).  I do get my own voice through MY speakers on the front jack AND the mobo jack.
    Hopefully I got you enough info!
    Thanks in advance!!!

  • RDP Port Forwarding non-functional

    OK, so I'm having yet another issue with my RV220w. I thought this would be a wise buy, but I keep finding reasons to hate myself for buying this router.
    Anyway, I need to forward port 3389, Windows Remote Desktop Protocol to one of my internal servers.  I have defualt NAT, defualt firewall, etc. etc.  I have seen documentation that says that Firewall -> Port Forwarding is non-functional, so I attempt to set up port forwarding via Firewall -> Access Rules.  I did not see "RDP" or any other obvious acronym for Remote Desktop Protocol in the services list.  So, I made a custom service, called RemoteDP, TCP protocol, port 3389 to 3389.
    No, I cannot RDP to my server from WAN.  What gives?  This was easily achieved with a cheap NETGEAR router from 2005.
    Very confused, and therefore disappointed.

    Join the club. . . .I have the same issues with custom rules and have been trying to get it to work for over a month now. I can only stall for so long with this problem. I need to get some ports open for established services that also was not a problem with a residential Netgear router.

  • Pavilion dv5=1233se - USB ports are non=functional

    I am running Windows 7 Home Premium on my system, when I started iTunes the USB2 ports failed to recognize any attached hardware (mouse, iPod memory sticks, etc.)  I have downloaded and installed the latest drivers for my mouse and upgraded iTunes.  I have gone through removing the "USB Roots Hub" and then scanned for new hardware.  The USB Root Hub's were recognized and show they are working properly.  I have also done a recovery to a date prior to this problem, but the USB ports are still non-functional.  Any ideas?

    This is the BIOS problem!!! I'm experienced the same problem with an usb hdd. Unfortunately the newest BIOS was faulty I guess so it's been removed. You can't do anything until a new BIOS will be released but it might take months...
    I'm able to connect some devices over an usb hub and reinsert cca 2x or 3x that usb hdd to get it work.

  • Am I correct that none of the latest iMac's have a DVD Drive or Firewire port?

    Am I correct that none of the latest iMac's have a DVD Drive or Firewire port?

    I actually use an external optical drive as all of my family and friends (including the ones in other countries) prefer to get the movies I produce on a DVD they can put in their DVD player and watch on a big screen TV, so I will be using that technology for some time to come. I also prefer not to upload anything as most everyone thinks everything is free to download (steal) other people's content. I've used an external burner for years because the super slim vertically installed drives in iMacs were less than reliable and any media could shift by 1/100th of an inch.
    My current (new) external burner is from OWC:

    (they have others, including bluray). Mine is quiet, sturdy, and offers several plugin possibilities.

  • Firewire ports non-responsive

    I'm hoping someone might be able to shed some light on a problem I'm having.
    Both my firewire ports have power but devices fail to show in iTunes or Finder. I've tried my iPod and my Lacie hard drive with the same results.
    I have done the following to try to resolve the problem.
    1. reset SMU
    2. reset Pram
    3. did an open firmware reset (reset nvram, set defaults, reset all)
    4. ran hardware test with logic board showing okay
    Anyone have any thoughts or suggestions?
    Thanks in advance.

    FireWire ports have been known to fail. The front port on my Power Mac G5 failed and I had to get it repaired (thankfully under AppleCare at that time). Mine also provided power, but no data connection.
    You have done all the things I would have tried except for one. Starting up from a different system to see if that made any difference.
    If you don't already have an external drive with a bootable system on it, you can use your Mac OS X installation disc. Start up from the disc to get to Installer. At the first Installer screen (after language selection), go up to the menu bar and select to run Disk Utility, from under the Utilities menu.
    Then connect your external drive to the FireWire port. See if the drive shows up in the Disk Utility sidebar. If it still does not appear, there is a good chance you have a hardware issue with the port. If it does show up now, the port is probably fine, and there is some issue with your current system installation.

  • Full Firewire Port Failure (three different machines : iMac Intel, iMac G5, Black Macbook)

    I'm experiencing a failure of all FireWire ports on all of my three machines. I believe this problem began with a faulty external, FireWire powered hard drive from G-Tech. Here are all my specs, followed by a rundown of the order of events that has lead to this situation, followed by the various troubleshooting I have done.
    Equipment :
    iMac Aluminum Intel - 24" Mid 2007 - running OsX 10.5.8 - currently 1 FW400 and 1 FW800 ports disabled
    iMac G5 - 20" - running OsX 10.5.8 - currently 2 FW400 ports disabled
    MacBook - 13" black Early 2008 - running OsX 10.5.8 - currently 1 FW400 port disabled
    2 500GB G-Drives (by G-Tech) - AC powered
    1 5TB G-RAID Drive (by G-Tech) - AC powered
    1 250GB G-Drive Mini (by G-Tech) - FW powered
    Initial Setup :
    1 500GB G-Drive connected directly to iMac Intel via FW800
    1 500GB G-Drive connected to first 500GB G-Drive via FW800 (daisy chained)
    1 250GB G-Drive connected to second 500GB G-Drive via FW400 (daisy chained)
    1 5TB G-RAID connected directly to iMac Intel via FW800>400 adapter
    Sequence of Events :
    I had transferred some files to my G-Drive Mini in order to move them to my MacBook from my iMac Intel. I copied the files to the G-Drive Mini and ejected it normally and plugged it into my MacBook via FW400. The drive would not mount, and the power indication light would not go on. After experimenting with various connections and cables I was able to get the drive to power with FW400 and USB connected at the same time, but the drive would still not mount.
    I then plugged the G-Drive Mini back into the 2nd 500GB G-Drive as it was previously connected via FW400. This action caused the G-Drive to immediately reboot and eject itself from my iMac Intel.
    I then attempted to plug the G-Drive Mini into my older iMac G5 via FW400. Immediately upon plugging in, the computer shut down, and would not restart.
    At this point I kind of started to freak out. I was unaware of the extent of the damage, but was upset that the FW powered G-Drive Mini had shutdown my iMac G5. I contacted G-Tech Support and they offered to replace the drive and instructed me how to manually reset the computer's SMC by opening up the iMac and finding the Cuda switch. This worked and the computer was able to start and function again, but the FW400 port seemed to be disabled.
    I then tried to swap out configurations and drives on my iMac Intel to see if there was any cable problems, but doing so, slowly rendered all my FireWire ports useless. It's almost as if the act of plugging in the FW-powered G-Drive Mini started a kind of shortout chain reaction. I soon learned that none of my hard drives would connect to any of my three machines, with any kind of cable combination via FW400 or 800.
    I am currently able to connect my 5TB G-RAID drive to any machine via USB, as well as my G-Drive Mini. I am unable to access the other two external hard drives, as one has only FW400 and 800 ports and the other's USB connection is not functional as well on any machine.
    Troubleshooting Steps Taken :
    I have on all machines, reset the SMC in the following methods. iMac G5 - manually, by opening the case and pressing Cuda switch. iMac Intel - unplug, hold power button, restart method. MacBook - unplug, hold power button, restart method.
    I have also on all machines, reset the PRAM by the Cmnd + Opt + P + R method at startup.
    I have also unplugged all cables / removed battery, from all machines and left alone for a period of at least 12 hours, then re-plugged in each device one at a time.
    I have also restored my hibernate mode (through Terminal) on my iMac Intel to mode 3 and also turned on Virtual Memory in system preferences and set hibernatemode to mode 7, the restarted and attempted to plug in devices. The reason I even began to deal with the hibernate mode was because I had around the same time my ports began malfunctioning, installed the DeepSleep widget, which allows you to control your computer's hibernate mode. I thought that tweaking with this setting may have made my computer incapable of recognizing devices that were plugged in. I have since uninstalled the widget and experimented with different hibernatemodes to no avail.
    I also have Repaired Disk Permissions and Repaired Disk on all my machines, from within my Admin User as well as from the OsX Install Disk.
    Sometimes in my System Profiler (like right now for example on my iMac Intel) my computer is "Unable to list FireWire devices," but sometimes, no warning message comes up and it simply displays the appropriate Bus speed.
    I also conducted a system restore using a backup from my 5TB G-Raid Drive via USB, to a date before these problems started, but my ports are still not working.
    Summary :
    I am looking at a situation where all my FW ports on all my computers appear to be disabled, and possibly also on my four external hard drives, with one possible USB port malfunction on one external drive. The only root of this seems to be a malfunctioning FW-powered external hard drive.
    Is this possible? Has this happened to anyone else before? G-Tech assures me that it is impossible for my 250GB G-Drive Mini to draw enough power from a computer to permanently disable any ports, but I have tried all of the FW port problem troubleshooting steps and am at a loss.
    I do not have AppleCare and would like to avoid bringing two iMacs, a MacBook and four hard drives to the Apple store and take my chances with the geniuses.
    I would appreciate any help or advice you all have. Thanks for reading and for your support!

    Ok. So if that was too confusing, I've re-labeled this post with letters for my hard drives and some mapping of the connectivity configurations I have attempted.

  • Wired interface non-functional

    So I have a most unusual problem with a mac mini server that is driving me banana's that I hope someone in the Apple community has run into, and found a decent solution..
    The mac mini (2.3GHz quad core i7, late 2012) is running 10.9 and server 3.0.1.   I did an upgrade from 10.8 (and whatever the previous version server was)..
    Since then the wired ethernet interface (en0) literally stopped working. (Links up, but no connectivity.. no ping, it does not even send an ARP)
    Data points about the problem.
    - It worked flawlessly up until the upgrade to 10.9.
    - wireless interface is still fine, static or dhcp.
    - The IP is statically configured via System preferences - Network.
    - ifconfig in terminal show NO IPADDRESS assigned to the interface.
    - if I reconfigure the interface to DHCP, it will not receive an IP and ends up with an APIPA address..
    - if I go into terminal and 'ifconfig en0 down' then 'ifconfig en0 <IP> up' the interface works again until restart.  It will also correctly display the IP in terminal.
    - If I reset, it goes back into this same state (network preferences shows proper config, ifconfig does not, and the interface is non functional)
    - If I then go to cli, and manually ifconfig down then up, all is good again..  Doing so from system prefs has no affect..
    Here is where it gets really interesting, and why I am convinced this is a software issue..     I did a clean install of 10.9 and Server on an external USB disk, and things work exactly as expected if I boot from that Volume..  If I boot from the internal drive, Its in the broken state again..
    This absolutelty tells me its some kind of software issue, and I am out of ideas short of wiping the internal drive, and reloading all the data from scratch..
    Anyone else run into this?  If yes, were you able to fix it without wiping/reloading?

    First, thank you for taking the time to respond and offering great ideas..
    I'd delete the interface & recreate it.
    In 'System Preferences > Network tab' select the ethernet, click the - button. Then add it again. Reboot & see if it has any effect.
    - Had no affect..  More accurately, it works the same as doing ifconfig down/up in cli, where the interface will work again until the next reboot.
    See what appears in Console (Spotlight search for it) in the 'All messages" section when you remove connect the ethernet.
    - Log messages are below..  Interestingly, I do not get the failure messages that I have highlighted in red on another machine that is is also running 10.9, with server loaded.
    11/23/13 10:14:36.000 AM kernel[0]: AppleBCM5701Ethernet [en0]: Link down (womp disabled, proxy idle)

    Have you tried changing the port on the switch it is connected to?
    - Yes, for ease of testing I have it plugged directly into my MacBook Pro  (I also tried new cable first )
    Does safe mode have any effect?
    - No, Same results.
    Again, booting the machine from a clean install on a USB disk, does not show the issue..    I’ve got a lot of data on the machine, so I am doing anything I can to avoid wiping and reloading it all..  Ive added the output of etrecheck, in case its of any help.

  • Firewire port PARTIAL malfunction

    Hi there. I have a Titanium PB. All of a sudden stopped mounting my external hard drive or the iPod. The strange thing is that both get their power in- the iPod starts recharging, and the external drive (LaCie 160GB) starts spinning, but none of them mounts. Since the problem started I've upgraded to Tiger 10.4.2, but the problems still persist.
    Any ideas how to fix it, or how to find out if this is software or hardware problem?
    Thank you in advance for the help.

    My TiBook's FireWire port has been in that condition for four days now, but the problem crept up on me over a couple weeks. My external drive (LaCie 80GB) would cut out unexpectedly, at first only when it was moved and then frequently and for no obvious reason. More recently I was forced to jiggle my cable to get any connection at all. (Substituting the cable made no improvement.)
    When I plugged in the drive Wednesday morning, the display covered over in horizontal lines. I got that sinking feeling and braced myself for the worst, but the lines disappeared as the screen redrew. That the PowerBook has continued to function normally (FireWire excepted) strikes me as nothing short of a miracle. The port on my TiBook smelled burnt out. Slavix, can I suggest that you sniff it?
    (I can sort of see how a short might kill the data pins but not the power pins. And reading the other posts in this category makes me suspect that using the FireWire bus power rather than the adapter may have contributed. I had no alternative, so no regrets.)
    Checked the drive on another Mac; data is intact. Tried booting up the TiBook in target disk mode, and that same Mac does not recognize it. I think that rules out software.
    Since there's no chance that I'll be able to send it in for service anytime soon, I suspect my only support option is to hope for the best, and maybe to purchase a FireWire PC card. I'd love to hear another.

  • 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.

  • No FireWire ports were found on MacBook Pro 15.4" running Mac OS 10.6.4

    Hello all,
    I recently bought a Mac Book Pro with Intel Core i7 and 2,66 GHz with a 4 GB RAM. The system is good, until I connected my external hard drive from Mac Way that connects to the laptop through a Firewire 800. The HD mounts well with a USB but not with a Firewire 800. I then went to the System Profiler and found this message in Hardware/Firewire - No FireWire ports were found.
    I restarted the system and the system hangs or takes like three minutes to start, usually it starts in less than a minute. So I pressed on the power button for 5 seconds and again started the machine.
    This time, surprise the HD mounts and in the Firewire in System Profiler, I have Firewire Bus, and when I click on it I have OEM ATA Device 00 and below

    Does any wise ones have suggestions out there? Thanks in advance for your kind help.

  • My external hard drive and cd burner does not appear on the desktop of my mini.  Using Firewire adapter from old to new firewire ports.

    I have a new Mac Mini (2013) and older external hard drive (Lacie) and cd reader/burner (EzQuest).  Both have the original Firewire ports and the Mini has the new kind.  I bought a cable with both kinds of ends but I plug them in and they don't show on the desktop.

    From what I've heard, sometimes certain devices will not have full functionality if they are FireWire 400 with an 800 adapter. Take Apple's original iSight external webcam. It had FireWire 400, and people report using a converter cable will give them video, but not audio.
    When I first got my mini, my usb cd burner wasn't recognised by Finder or Disk Utility. After repairing disk permissions and a reboot, it worked fine.

  • 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.
