Firewire 800 hub not working

After two years without incident, all my drives (5) stoped mounting on my 17" Macbook Pro (running Lion). They are connected though a hub -- NitroAV 8 port Firewire 800 hub. I have changed the cable -- no effect. I have tried connecting the drives individually to the port -- they all come up immediately. So I am concluding that it must be the hub itself. Right? But is it usual that such a hub just stops working? What can be wrong, and can it be repaired? Or is it better to just buy another (expensive) one? Thanks for any ideas! Norris

Hi Todd DeNoyer-
Tom offers excellent advice. The only way to narrow this down is one drive at a time.
Are you using a FW800 hub or do you only have one drive?
Some LaCie drives in particular have power supply bricks that can malfunction and give absolutely no clue-the light comes on and the drive spins up. When this happens, the drive with the bad brick will try and draw current from the bus and wreak all kinds of havoc.

Iomega eGo 2TB USB/Firewire 800 drive not working with Time Machine.

The drive I had for Time Machine died and I replaced it with an iomega eGo 2 TB USB/Firewire 800 drive. Time Machine finds it and backs up the disk when I first boot up but then it seems like the drive goes off line. At that point, when Time Machine tires to back up it can't get the drive to respond and my system hangs. To fix that, I turn off the iomega that fixes the hang up and I get the disconnect without ejecting warning.
I ran disk utility and disk warrior. Both apps reported the disk is fine.
Can any tell me what's up? I'm running OS X 10.7.2
Thanks.

I am having this exact same error with my new iMac 21.5" connected to a brand new Iomega eGo 2 TB Desktop Firewire 800 External Hard Drive (Mac Edition - 34796).
The TimeMachine backup works fine, but as soon as the iMac goes to sleep and wakes back up, TimeMachine doesn't respond well to any commands and all sorts of errors appear on the screen.
I will try the tip here from Kappy and report back later if this works for me.
Kappy, one thing to note is that I'm using the Firewire connection from the iMac to the eGo and experiencing this problem. The eGo has its own power supply too.

Rear FireWire 800 port not working

After installing Leopard, I connected my TimeMachine external FW 800 drive to the rear FW 800 port, but it was not recognized. I also have an external drive connected to the rear FW 400 port, and it works normally. After some experimentation, I found that if I unplug the FW 400 drive, the FW 800 port becomes active allowing the TimeMachine drive to mount. But any time I use the rear FW 400 port, the rear FW 800 port doesn't work.
The front FW 800 port works normally, and I'm using it for TimeMachine. But I'd like to keep the front ports open for tempory use.
Before calling AppleCare about this, I thought I'd see if anyone has any suggestions about things to try.

Thanks--I tried power cycling (as well as some other suggestions found on Mac sites) but so far, nothing has worked. If I start up with just the FW 800 drive connected to the rear port, it mounts. But as soon as I plug a cable in to the adjacent FW 400 port, the FW 800 hard drive dismounts with the error message that it wasn't unmounted properly. The FW 400 cable is connected to a powered FW hub, but none of the devices connected to the hub are powered on. I also tried another FW 400 cable connected directly to a FW 400 hard drive instead of the hub, but the FW 800 drive still won't mount.
I'll call AppleCare and see what they say--not looking forward to taking the Mac Pro into the shop.

IMac firewire port is not working

iMac firewire port is not working
Hi everybody, Happy New Year.
I am a 72 years old semi-newbie in video editing, because Iedit only 1 or may be 2 movies a year since 2007 and I have only very little computer knowledge.
I received a new 27” iMac as a birthday gift 14 months ago. About 10 months ago, with help, I successfully use the Migration Assistant to transfer some datas from my old power G4 to the iMac including two Final Cut Express projects. I had one project successfully done; burned to DVD and I save it with Print To Video. Last week, I have my second project done, I burned the sequences into DVD but unable to do a Print To Videodue to the iMac is not communicating with my Sony camcorders DCR VX1000, this is the same camcorder I used on the last job which was working a couple of months ago.As a result, I try to switch the Easy Setup with different Format and different Use; I refresh the Canvas window; I did a Mix down; move the Screen Saver to NEVER as well as the Energy Saver set to NEVER SLEEP. I also trashed the preferences (plist) folders; run the Utility repair, I replaced the firewire cable (4 pines – 9 pines 800), but nothing work. Up to this point, I think that there is no signal from the firewire port to the camcorder because I understand when the sequences is ready, the firewire is connected between the computer and the recording camcorder, the Print to Video is activated, then the word DV- IN should be seen on the recording deck screen. This time, I don’tread such words on the recording screen. Therefore, I think there’s no out going signal from the iMac to the recording camcorder and the iMac is not receiving signal from the recording camcorder. At this point, I try to connect my iMac to the power G4 to see if I can do some data transfer. Follow the procedures, I hook up the data transfer cable between the G4 and the iMac, I can the fireswire icon moving on the G4 screen but no indication on the iMac screen (there should be some indications in the source bar), this shows me the iMac did not recognize the G4 which worked on previous data transfer. It looks to me the firewire port on my iMac is dead. What has gone wrong? Could I accidentally disabled the firewire port by some magic keystroke? (i.e. accidentally fat finger some thing to make it stop working? Oh, by the way, during the playing around, went to the Final Cut tool bar, I click the View >Video Out > Digital Cinema Desktop Preview – Main, the result was a black screen and the esc key was my rescuer - LUCKY LUCKY! Are there any other trouble-shooting techniques to apply before bringing to shop? Please help!
Sorry for such a long statement, forgive me for unable to make it shorter. Thank you for your patience. Thanks to all the folks in this board for being so helpful.
p.s.

Not sounding good.
If the system Profiler does not see it then there is a basic communication problem between camera and the Mac.
I'm thinking the Firewire port is the culprit as some 800 ports were faulty.
I'd suggest taking the Mac, cable and camera to your nearest Authorized Apple Service Centre and get them to diagnose the issue. eg. let them try to connect the two devices.
Right (control)click the Sequence icon in the Browser and select Item Properties, do the same for a clip.
You can also post screen shots for the Properties.

FireWirer 400 Ports not working, Fix and/or Add PCI FireWire card

Here are some details about my G5:
Hardware Overview:
Machine Name: Power Mac G5
Machine Model:PowerMac7,3
CPU Type: PowerPC G5 (3.0)
Number Of CPUs:2
CPU Speed: 2.3 GHz
L2 Cache (per CPU): 512 KB
Memory: 2 GB
Bus Speed: 1.15 GHz
Boot ROM Version:5.2.4f1

I have two FireWire 400 ports that aren't working. I normally use the FireWire 800 port, which works fine.
I've tried:
- Resetting the NVRAM
- Resetting the PRAM
- Resetting the SMU
I haven't been able to run Apple Hardware Test, it is not on my install disc and I must have lost the separate Apple Hardware Test CD... annoying!
1) First Question - Can I do any more to fix the FireWire ports?
I also have a FireWire PCI card, which looks like this http://www.newegg.com/Product/Product.aspx?Item=N82E16815150103 though I can't be for certain that is that one (PCI card purchased by my business partner 4 years ago and was originally in a PC). It's got 3-ports (2x 800 and 1x 400).
2) Second Question - am I ok to install this FireWire PCI card into the G5?
(how do I identify for sure what make of PCI card it is?)
If so, which slot and how should I go about doing it?
Thank you

Hi sohopigeon, and a warm welcome to the forums!
What to do if your computer won't recognize a FireWire or USB device...
If the issue persists, try these steps:
1. Shut down the computer.
2. Disconnect all devices and all other cables, except the keyboard and mouse cable(s).
3. Disconnect the computer from the power outlet and wait for 3 to 5 minutes.
4. Plug the computer back in and turn it on.
5. Reconnect the device(s) (one at a time if there is more than one) and test. Test with each port if you have more than one.
http://support.apple.com/kb/HT1317
The 7,3 2.3 was PCI-X, I notice this PCI card is NOT for use in PCI-X G5s...
http://eshop.macsales.com/item/Other%20World%20Computing/PCIFW4P/
While this one works in PCI or PCI-X...
http://eshop.macsales.com/item/ADS%20Technologies%20Inc./API315/
Not sure about yours, but it does say...
PCI 2.2 compliant and works in 32-/64-bit PCI slot
Works in 3.3v or 5V PCI slot
The one that doesn't work in yours above is also PCI 2.2 compliant.

Migration Assistant 10.6 only recognizing Firewire option, still not working

I'm attempting to use Migration Asssitant to transfer a user from a MacBook to an iMac. Both systems are using 10.6.8 and are on the same wireless network.
PROBLEM 1 – Migration assistant is only giving the option of transferring via FireWire; it won't give Ethernet or Wireless options. Yes, with an Ethenet cable connected between the computers, and yes, with the computers on the same wireless network.
PROBLEM 2 – Even over Firewire it's not working. With the MacBook in target drive mode, the "Select the System to Migrate From" window shows two drives, both named "Button". Button is not the name of the (one) drive. Selecting one or the other brings you to the "Pick Users To Transfer To This Machine" page, which just hangs forever.
Super frustrating. Help? I couldn't find anything else about this in the forums.
--J.

Try this. Erase the iMac, reinstall the OS, and on first boot, use the Setup Assistant. See Pondini's Setup New Mac guide, which should be comparable to what you're trying to do. BTW, no need for TDM.

Belkin Firewire Hub Not working

I purchased a Belkin Firewire 6-Port Hub unit and plugged all of my firewire gear into it and it is not working. The unit is glowing green and is connected to my iMac so that is all good.
I read the back of the package and it says the following....
To use the hub your computer must feature a built in firewire host adapter or be equipped with a firewire host adapter upgrade card.
Does the Intel Core 2 Duo based iMac have either one of these? Could this be my problem?

I had one external hard drive plugged in (with its own power supply), my Digi002 Rack plugged in (with its own power supply) and a cable to my camcorder. I turned my hard drive on and the icon would not appear. I just unplugged everything and now the hard drive works. I guess I will just take the belkin back or sell it on amazon.
I have a belkin usb hub and that thing works great! I guess the firewire hubs are kind of finiky.
There really was not exact place to plug the firewire cable into the hub that connects to the computer, unlike the usb hub. I thought that a bit odd. Perhaps I pluggede the cable from the computer into the wrong spot on the hub so the hub was not recognized by the computer?

Will a Firewire 800 hard drive work on my MacBook with Firewire 400?

Hi, I have a MacBook I bought in 2008. The FireWire specs say " Maximum Speed: Up to 400 Mb/sec"
I am considering a new external hard drive (the Iomega MiniMax) and want to use Firewire for this one. The specs for the hard drive say: "The MiniMax includes 2 fast FireWire 800 interfaces, a USB 2.0 hub, plus a FireWire 400 to 800 cable."
Will this FireWire 400 to 800 cable allow me to plug my FireWire 400 laptop port to this FireWire 800 harddrive port? It sounds like it will but I wanted a sanity check before I order it.
Thanks.

Yes, that should work just fine.

Thunderbolt to Firewire 800 adapter not enough power

Warning to those who own G-Technology G-Raid Mini (Gen3) and a Macbook Pro Retina.
I just received my thunderbolt to firewire 800 adapter from apple yesterday. I hooked it up to the rMBP and plugged in my G-Raid Mini, the G-Raid Mini powers up, but then proceeds to make a beeping noise. The G-Raid Mini will not mount over bus-power thunderbolt to firewire 800 adapter. Although when I plug the G-Raid Mini into wall with power supply and then plug in the thunderbolt to firewire 800 adapter, the drive mounts.
It seems there is not enough thunderbolt bus power to mount a G-Raid Mini (Gen3)...
Has anyone heard otherwise? Can they confirm this doesn't work for them either.
Thanks.

Same for me.
Luckily I tested it is advance of playing a gig at the weekend using Serato.
Complete JOKE!
I can't believe that Apple hasn't considered the fact that the majority of creative professionals need high capacity fast mobile storage.
I suppose we now need to wait for 2Tb Thunderboth enabled SSD drives which by my reckoning will cost more than the MacBook Pro!!!!

Macbook Pro WD Firewire 800 issues possible work around

I have been having issues with my Western Digital My Passport Studio and the Firewire 800 connection. The drive would mount and was completly readable however copying to the drive would result in a stall. The USB connection worked perfect. I have found if I disabled the Wi-Fi connection I could then write as usuall without error.
I have read of people having issues with thier firewire connections and am curious to know if this helps anyone else. The most popular responses have been RMA the drive or the Macbook. I have also read peoples dealiings with Apple thus far have not been very helpful either. Hope it helps seems to be working for me thus far. Hopefully a fix is in the works 'cause I love my MacBook and the drive.
This is the current (late) 2011 MBpro with OsX Lion 10.7.2

I can only answer part of your question. Your SLR has mini HDMI and a mini USB out. Your MBP has three ways to connect: USB, FW 800 (9 pin) and Thunderbolt (which is ao far supported by a limited number of devices).
As far as I know, you will not be able to use On Location with the Canon. But I could be wtong. Good places to ask are the Adobe forums and Canon forums.
Good luck.

Any Firewire 800 Hub recommendations?

So I have been thrilled with my new iMac.
But of course the one limiting factor with the new iMac is the single FW800 port when having multiple FW drives. Daisy chaining of course works, but it also forces you to power up all drives in front of the drive you want in the chain.
On my eMac I had a Belkin FW (400) hub and it was great for having several drives attached to my system and only having to power up the one drive I actually wanted to use.
Anyway, has anyone tried any of the very few FW800 hubs available? And if so how does it perform?
So far I have only run across 2 or 3 models and all are very expensive.

If you still have that 400 hub and only 400 devices, you can connect it to the 800 port through an adapter (or a cable with the right connectors). If you have one newer 800 device and the rest are 400, connect the 800 device directly and connect the hub off the daisy-chain port. Then connect the other devices to the hub.
Ya there lies the problem, well more of an annoyance than a problem. I have a FW800 drive, so that is plugged in directly to the back of the iMac. I then can daisy chain other FW400 drives off the back of that drive. But it still requires that drive by turned on to get to anything I daisy chain off of it. That FW800 drive has a fan so it is kind of loud so I rather only have it on when I am specifically using the drive.
If the iMacs had TWO FW800 ports then I could plug the FW800 drive into one and my Belkin FW400 hub into the other and then all the FW400 drives into that. Then all drives could be independently powered and will be seen on the Mac.
Hopefully, that will be sufficient until some other third parties create 800 hubs and bring the price down a bit.
Ya, so far I have found two possible hubs but at $$$. One is a three-port FW800 hub for $50 which would give me my two FW800 ports as mentioned above. The other was a nice looking 6-port FW800 hub giving me 5 FW ports to plug drives into that could be powered up and mounted individually. However that one was $100!!!
For the three port one, it almost seems better to find a FW800 enclosure with three FW ports on it (typically two FW800 and one FW400) and don't put a drive into it and use it only as a hub (but have the option of popping in a drive). However I haven't run across one that is cheaper than the 3-port hub yet. But if I get a fanless one, then I can run a drive in it and use it as a mini-hub and not have to hear a fan running when using it mainly as a FW repeater and not actively using the drive in it.
The search continues!

Is there such a thing as a Firewire 800 Hub (like a USB hub)?

I'd like to have a firewire port "at the front" of a Mini, for easy attaching of a Camcorder-firewire line or other occasional-use Firewire devices. The one FW800 port at the back of the Mini has external hard-drive(s) attached.
Ideally, I'd like a hub that splits this FW800 into FW800 and FW400 jacks (2 of each)! But I've never seen such a hub, and am not getting clear answers from hardware vendors. USB hubs are easy to find, but Firewire?___

Google "Firewire hub 800" and several come up;

Firewire 800 device not recognized after a power cycle

I picked up a Seagate FreeAgent Desk | Mac edition (1 Terabyte) a few weeks ago and the first thing I did was format it on my iMac (it came formatted, but I figured it wouldn't hurt). I also wanted to make sure it was done right. So I know the FS works great with this iMac.
As you may see, I have a 3.06 24" iMac to give you an idea of what machine this is being plugged into. The one FW 800 port in the back.
I picked 1394b (FW800) because the speeds are so impressive - and so far this drive is working great! With one exception ..
When I power the machine down & bring it back online, the drive does not automatically come back - and I have to disconnect either the power, or Firewire 800 cable (which I've tried two of - the stock one with the Seagate product and another high quality cable). After that it's smooth sailing.
I just want to get this device working between boots so I can rely on it to take my time machine backups without worrying about fiddling with it to get it working.
Any suggestions would be appreciated, and unfortunately this is my only FW 800 device (not much troubleshooting possibilities). I'm looking to buying a WD MyBook Studio 1TB Fw800 drive - but I won't be doing that (yet) if the port is my issue and not the Seagate drive.
This link is to an image in which you can see my Fw settings in System Profiler.
http://i39.tinypic.com/105dz4y.png
I've been reading the Seagate forums looking for some help, and there seems to be issues with the drivers powering themselves off and confusing the OS, but this doesn't look to be the case. Unfortunately I've got 700GB of data on this drive and will need to move the contents to my on-board drive so I can format the unit with Fat32, plug it into an XP PC (gogo upstairs) and run the Seagate Manager.exe and see if I can modify the power settings (all on a whim, awesome).
I'm just curious what I should do - I don't live in a city where there's an Apple store but there is an Apple authorised reseller/service centre. It looks as though I'll be heading there to see what's up.
Has anyone else seen a problem like this?
Thanks in advance,
hENN

not enough specific information about what caused the problem but I'll give you some pointers to ALWAYS follow with firewire drives. I've been using them for many years without issues through all the OSX versions.
If Mac is powered on: power on seagate and wait a few for the hard drive to spin up, connect firewire cable to Mac first then Seagate. When done : a) unmount the seagate listen for the hard drive to complete its cycle then power seagate down, remove firewire from Mac first then seagate. b) or just power down Mac then power off seagate when the Mac is done.
If Mac is not powered on: connect firewire cable to mac and seagate, power on seagate and listen for hard drive spin up to complete then power on Mac.
The problem with firewire is, if user makes just one mistake with the above then firewire recognition comes into play, such as device will not mount to desktop, etc. Sometimes user gets lucky and nothing happens but consider that rare.
So if user does have firewire troubles , what to do? Not fool proof but many times successful, disconnect external power and all cables and power cycle the external on/off a few times but listen for hard drive spin up and spin down. On the Mac either one or both zap the pram and or power manager reset. This works many times but does not save an external if user highly abuses the procedure. You can also apply this to USB troubles.

Western Digital 3T Firewire 800 will not boot iMac

The internal drive on my iMac (intel) is small (300G) and corrupted. My idea was to buy an external firewire 800 drive and use it as the boot disk.
I bought the western digital "My Book Studio" drive (WDB3G0030HAL). I installed the system from time machine backup and it wouldn't boot so I reinstalled Mountain LIon using the recovery partition. After that, I learned it will boot my macBook Pro but still doesn't boot the iMac.
I have found older articles about western digital having problems getting external drives to boot.
Does anyone have newer information or work arounds?
thanks
Dwight

Here is a list of WD bootable drives:

You can check to see if yours is on it.
FWIW, are you saying that you have one backup and are trying to boot two different machines with it? Unless the two machines have the same build, that is not possible - Macs simply cannot be booted or run with a system version older than what they came with.

Firewire port - does not work

Firewire 800 port does not work on my iMac, mid 2010 version.
If i plug in an external disk with external power it does not work. Sometimes the disk are recognized, but then it says its half the size it really is.
On small disks without external power it works.
I have tried 6 different LaCie disks with firewire 800 - all works on my macbook pro.
I have tried 2 differne western disks with firewire 800 - all works on my macbook pro.
All disks works as they should with USB.
Is it possible to reset the Firewire port?
If so, please send me a LINK. This support pages are **** to find correct answers…

While you can't reset the FW port on it's own you can do a number of different resets including SMC & PRAM resets, you can also restart in Safe Mode which will clear some caches. It's possible one has become corrupt. Try these first and sff i you have any luck. Make sure ALL peripherals except the keyboard and mouse are unplugged when doing the resets. Also it is not a bad idea to do each reset 2-3x to ensure it's worked.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
