FIREWIRE DRIVES NOT MOUNTING OR BEING RECOGNIZED

After a recent software update, I cannot get my 3 external Firewire HDs to mount or even be recognized. Often in the past I needed to mount the drives via Disk Utility, but they were are always recognized.
I've had this problem before – usually after software updates – but I've been able to resolve it... up until now.
Here are the steps that used to work either alone or in combination:
• Restart (duh)
• Run Cocktail and/or repair permissions
• trash com.apple.ats.plist and com.apple.bezelservices.plist (for some reason I no longer have com.apple.ats.plist in my preferences)
• disconnect all externals, shut down for a while, restart and reconnect
I was able to mount one of my drives via USB (slow), but the others are Firewire only.
Anyone have any suggestions?
Thanks!

It really sounds like you need one of these...

In the meant time pull that one, pull the A/C power, disconnect all peripherals, even Monitor, Printer, KB, Mouse, let set over night...

Hard drive not mounting or being recognized by my MacBook???

Hello,
I have a Glyph external hard drive that, all of a sudden, is no longer being recognized by my computer. I does not show up in the system profiler nor in disk utility. It connects using firewire. I have connected my digital camera via firewire recently and it was recognized. I have also connected this hard drive to another (newer) mac and it has no trouble recognizing it. So it's seems that it is not the firewire jack in my computer that is problematic nor is in the actual cable. Any suggestions? I don't even know where to start as a i have nothing to work with.
Thanks in advance.

hello,
as recommended in the link that was referred to me i have tried zapping the PRAM and
resetting the firewire ports. I was unable to turn off the spotlight indexing on the drive because it (the external hard drive) is not being recognized by my computer. Resetting the NVRAM does not seem to apply to my situation.
Still no change.
I just tried plugging in another external hard drive which is a newer glyph and it was not recognized through the firewire BUT it was recognized when i used the USB port. My hard drive only connects with firewire, this newer model (which is a friends) has multiple connections, hence the USB and success.
I don't know where this leaves me. It is obviously the firewire port or jack (whatever its called) in my computer that is troubled. I dont know what further steps to take.
I have contacted Glyph tech support and they seemed baffled. They recommended that i send in the HD so they can update the firmware (although they said it was "a shot in the dark"). Both my computer and my glyph are no longer under warranty so i obviously want to be sure i put my money towards the most likely conclusion.
Any further things i can try before i send the glyph out? anything?
thanks so much.

10.4.7 & FireWire drives not mounting

Hi everyone,
since this morning my trusted LaCie FW HDs won't mount, are not seen in System Profiler and Disk Utility.
I tried almost every thing I could find, resetting vram, pram, powering everything down, waiting, disconnecting all the cables, powering back up, connecting one after another, etc. - no changes.
Every application runs fine. Except, of course, Logic because I have all my sounds and song projects on these drives.
My system.log continues to say every second again:
...-Computer kernel[0]: AppleFWOHCI_AsyncTransmit::waitForDMA - context not going inactive.
The console.log repeats:
-Computer root[175]: [MAFL] attempt to make FSSpec for "121-210.cypress" failed -120\n
-Computer root[175]: [MAFL] attempt to make FSSpec for "210.cypress" failed -120\n
-Computer root[175]: [MAFL] found no firmware to load for 210\n
Does anybody know what these logs mean?
Is anybody else having this problem with 10.4.7?
I started a similar thread on A-S-D- Installation and Setup, only to find out, that a lot of people there are experiencing the same issue (FW drives not mounting, not showing).
Would resetting the PMU help?
Please help, I can't work

Back from the mysterious world of HDs, so easy to solve..., sometimes...
I tried the HDs on my friends older PB and all was fine.
Resetting my computers PMU did not solve the problem, after I tried everything else.
I refrained from reinstalling 10.4.7.
All other applications (but Logic, because I could not access my files) were running smooth.
Going back to 10 a.m. yesterday, basically starting over, there was one thing I missed checking (being human): the AC to DC converters supplied by LaCie for their drives.
See, they are under my desk, like out of sight...
Voilá! Individual testing revealed, that the AC/DC converter for the first LaCie drive in my chain did not spin up any of my other six LaCie drives, which I never run all at the same time, but they still have their own power supply.
Changed power supply on the first HD and now I am back to the fast speed and glitch free system I love. Back to enjoying work as well
What a day. And I am very sorry, that I was implying to blame 10.4.7 for this. My PB has never been faster

External Firewire drive not Mounting/Appearing!

I had this problem too with my G5 (PPC) and brand new Mac Book.
Both of my computers were given the same local subnet address. To change this go to System Preferences > Sharing > Computer Name, you'll see an "Edit" button, click on it and change the name or add a "2" to the end of the name before ".local"
I guess what is happening is both computers are using the same local subnet and your macbook isn't being recognized.
Mine works fine now, hope this has helped you!

Firewire drives not mounting on a G5

I have a G5 dual 2.7 and some external Lacie firewire drives. Suddenly the drives won't mount - don't even show up in Disk Util. I can mount them on an iMac just fine, but not on my G5. Any ideas? Many thanks.
G5, dual 2.7 Mac OS X (10.4.4)

Thought you could use this info about getting FireWire to work!
First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try. Yours is the 10.4.4 Combo update. Others reading, download the Combo that applies to your system.
If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good!
Good Luck!
Cheers!

Hard Drive Not Mounting After Being Magically Changed to Read Only

I was using a firewire connected, verbatim 1tb drive as a time machine. Everything had been working fine, but I walked away from my laptop for the morning and came back this afternoon to find my hard drive changed to read only. Time machine wouldn't back up to the hard drive; so, I rebooted.
Since then, I haven't been able to get the hard drive to mount. It won't show up in Drive Utility or on the desktop. I have rebooted the hard drive, unplugged it, turned it on and off.
What should I do? How do I fix this? It has my backups and my music. I'm no amused.

I've had exactly the same trouble this morning.
I'm using a MacBook Pro with my Time Machine on a portable Hard Drive. When doing my regular back up the computer froze. I force restarted the computer and the TM drive came up as 'Read Only'.
So, I rebooted again and the drive is not mounting at all. I can see it connected through System Profiler, however the drive isn't showing up in Disk Utility.
Does anyone have any ideas? Coz I don't seem to be the only one with this issue.

HELP! Firewire drives not mounting after crash

So I had two FW400 drives daisy-chained together. I was exporting a quicktime while simultaneously compressing another QT in Compressor. Apparently, too much for my computer to handle and I got the spinning ball of death. Nothing would force quit. So I had to shut down by holding down the power button. Restarted and neither drive will mount, daisy-chained nor individually. I plugged in a 3rd FW drive and it mounted fine, so I'm guessing it's not my Firewire Bus or PRAM or something internal to my computer.
Is it possible to fry these drives? Hope not as I have a lot of media on them.

Phew. I’m not sure what happened, but I ran the Disk utility from the Installer disc and no repairs were necessary. But while at it, one of the drives mounted. Then I power cycled the other drive and that one came online. So looks like I’m in the clear!
...Although, now FCP won't launch. The load window appears and the last thing I see is "Loading Audio Filters".

External Firewire Drive not Mounting

Hi, I've been searching these forums but can't find an aswer to my question. I just got a new 27" iMac, and purchased a Thunderbolt-to-Firewire adapter. I have 3 external Firewire drives, two of which are DC powered (the third, I understand, might be a lost cause, as it's bus powered, and I gather the bus power from TB won't power Firewire drives). At any rate, I'm not seeing either of the DC powered drives showing up, which is a big concern as I have about 5TB of stuff on them!
Any reason these wouldn't show up, either in the Finder or Disk Utility? Much thanks for any help!

Hi - did you ever resolve the dropouts? I have a new iMac purchased in Q1 2014 and connect my G-Grive to it via the Apple Thunderbolt to Firewire 800 adapter. My iMac runs 24x7 and this connection drops out on a regular basis - I'd say maybe once every week or so. I have a slightly newer USB3 G-Drive which is connected by the USB socket next to the TB socket on my iMac.
I cannot tell if it is a software issue or a physical (cable movement issue), the plug has never been out and I can't deliberately disconnect it at will by wobbling the cable/plug. So, evidence and experimentation suggests the physical connection is not the issue. This problem has only come about after switching from a physical FW800 connection (my old iMac) to working via a TB adaptor (my new iMac).

External Firewire Drives not mounting but shown in Disk utlilty

Well the title says it all!
I can see my ibook in target mode on my new macbook in disk utlity but not in finder!
I want to copy over my documents folders (I have tried migration assistant but it can't see the mounted drive either!).
It works fine the other way (i.e viewing the macbook in target mode on the ibook)
Details:
Macbook 2.2GHz (new model) 10.5.1
Help!

Is the Mount or Unmount button greyed out in DU when you highlight the Firewire icon? If you can click the Mount one, do so. If you can click the Unmount one, check the Prefs in the Finder menu to make sure that you are showing attached drives.

Firewire drive not mounting on startup

Just got a new 2.3 Dual Core running Tiger (10.4.4) and FCP 5. Strange thing is that I've connected a Lacie to the FW800 port, formatted it extended not journaled and it works fine...but...it doesn't mount automatically when I power my G5 on (I have to switch it on) nor does it switch itself off when I power off.
I have two other G5 systems running 10.3.9 and another 8 Lacies and WD drives connected to them an they all mount fine when I switch on and power off when i shut down.
As a matter of interest I tested one of my old Lacies, connecting via USB2 and this starts fine when I power up.
I suppose my next test will be with my other Lacies but thought I would raise it here in case anyone can help.
Any replies much appreciated.

Thanks for your reply Chris. I always have the drives plugged in but I don't usually need to actually power them up - they switch on automatically when I power up my G5. The reason I posted this query was because I've been using Lacies for about 4 years now including several on two other G5 systems I have and I've never had to manually switch the drive on or off before.
I was thinking it might be something to do with Tiger and the fact I am connecting via FW800.

Firewire drives not mounting

I have a firewire400 drive that refuses to mount on my G4 dual 1.25ghz ppc (the one that has fw800 and 400). i am running osx 10.3.7
The same drive mounts fine on all other computers I have, G5... and G4 aluminum powerbook. Any ideas would be much appreciated!

800 drives weren't mounting either.
With the power unplugged, I pulled the clock battery in and out, did a PMU motherboard button reset, then restarted.
then the external drives mounted once again.
<shrug> thanks for trying, but problem solved....

Firewire drive not visible on desktop

Firewire drive not visible on desktop
System profiler knows it's there.
Disk Utility indicates that it can be un-mounted (only a generic 'turned down page' for volume icon however), Disk has full Hard Drive logo...
But I cannot access it on this machine, but plug it into another and it's ok...

(only a generic 'turned down page' for volume icon however), Disk has full Hard Drive logo...
You can see that appearance in Disk Utility if the volume permissions are such that the current user has "No Access."
Since it can be accessed normally from another machine, connect it there and do a Get Info from Finder, looking at the Ownership and Permission Details at the bottom. Assuming this is not a startup disk, if any of the permissions is set to "No Access", change it to "Read and Write". Don't click "Apply to enclosed items" however.

Hi cecebabymusik,
Welcome to the Support Communities!
Try the specific steps below for the your iPod touch first:

If the issue is not resolved, you may need to uninstall iTunes and all of it's components, and reinstall the latest version as explained in this article:
