10.4.3 won't mount my external HD?

Help!
I have an external HD with all my music on it. It sits connected to my Mac Mini running 10.4.3. Yesterday I had to restart my Mac Mini (which I rarely if ever do) & now it does not see the external HD at all. It does not mount NOR does it appear in Disk Utility.
My other Mac (PowerBook 15) running 10.4.2 sees the drive fine & mounts it as expected. I have run Disk Utility & DiskWarrior from my PowerBook on the drive & though Disk Warrior did do a few fixes, the drive just does not appear on my Mac Mini.
I don't know when I upgraded the Mini to 10.4.3 - but I even re-updated it from the "Mac OS X Update 10.4.3 (Combo)" version of 10.4.3 as someone suggested - but still no luck.
I have also repaired permisiions numerous times on the Mac Mini....
Does anyone have any other ideas?

This may require resetting the firewire ports as described in this article:

My Mac won't mount my external HDD after installing Lion - What can I do?
HDD: Verbatim 3.5'' External HDD eSATA & USB 2.0 #48802
I can not find it in Disc Utilities - so I can not repair it.
I also haven't found any Driver for the HDD to do an update.
My Mac is running on the most recent updates of OS Lion.
The HDD worked before. It contains my former Time-Mashine Backups. I would like to use this drive again. It isn't very old yet.
It would be much appreciated if anyone could help.
Cheers,
Yves

OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and 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.

Had a problem copying files, now MBP won't mount the external HD`

Hi
I thought to put this in the MBP forum but since I thik it may be the OS I decided to post here.
I have a newer MBP with OS 10.5, I have an external LaCie c0nnected via eSata to keep my firewire 400 port free. I mounted another external HD to the Firewire port and the computer recognized it and I started copyig some files from the LaCie to the other external. Both formatted HFS+ Files were QT files. Somewhere during the copy process things locked up. I had to force quit the copy process, then coldn't restart the computer so had to ue the boot button to turn it off. Now I can't connect anything to the FW port. The MBP won't mount the 2nd external HD so I can get those files copied. I brought up my FCE and connected the external monitor to the FW port but now that doesn't work either and it was working this morning.
I hope I didn't blow the FW400 port! Is there any way to 'clear it' in case it's still looking for that HD? I don't kow if I'm asking theright way cause I'm really new to MAC's. I tried the Disk Utility to verify the disk and got an OK message. What else can I try?
Thanks
Allen

Hi VK
Well I didn't blow the FW port. My video editing partner came over today to discuss a project we're working on together. He has FC Pro and I have FCE4. So I mentioned the problem to him cause it was his HD that wouldn't mount.
We had FCE open so I was showing him my external monitor fed via the FW port wasn't working either. He went to the View menu then to Video out and then to refresh video devices. BINGO! The external monitor started working. So it wasn't the FW port but apparently the FW was locked up or looking for the other HD. Now it's working. But I haven't tried connecting another external FW HD yet.
Thanks for your help

Media won't mount via external optical after 10.4.4 update

I did a search of the forums and found nothing related to my problem, sorry if this has already been covered. This is my first post on the support forums, so please forgive me if this is posted in the wrong area, and feel free to point me in the right direction if I should be asking this queston elsewhere.
The subject heading says it all. I have an external Firewire DVD writer, and since I updated to 10.4.4 it won't mount any media when connected second in a chain after my external hard drive. If I disconnect the hard drive and plug the optical drive directly to the iBook, discs mount just fine, but when it is second in the chain ... nothing.
Additionally, neither Disk Utility nor Toast will recognise the optical drive in order to burn data unless the device is plugged directly into the computer.
The obvious solution would be to reverse the order of the devices, so the optical drive comes before the hard drive, but I have experienced problems with hard drive access and speeds of transfer to the hard drive when I've hooked things up in that order, so it is not an ideal solution.
Any help would be greatly appreciated and thanks in advance.

Dear Joel,
for me I have a solution. I had to turn spotlight off with "sudo mdutil -i off" and then to delete all the files in the hidden /.Spotlight-V100 folder and then turn spotlight on again. And then wait for the computer to index again BEFORE the restart. Can be observed in the activity monitor: task mdimport.
I found my solution on the following page:

IBook G4 won't mount LaCie external hard drive

A friend of mine, with a new iBook G4 with 512MB of RAM, is having some problem with an 80 GB bus powered external hard drive from LaCie. The problem he is having is he can't see his drive when he plugs it into his machine. He has tried plugging it in with a firewire cord and a USB cord, and neither have worked. In addition to not showing up on the Desktop the drive doesn't even show up under Disk Utility, however, the drive does show up under System Profiler. When it's plugged in with the firewire cord it says:
FireWire Bus: Max Speed up to 400 MB / sec
When it's plugged in with the USB cord, the computer says it sees a LaCie HD.
He has also tried plugging the firewire drive into another computer, that machine is also running 10.4, and the drive mounts without a problem. He has recently run software update and updated everything that was recommended, repairing permissions before and after each update.
Any ideas on how to fix this? Or, since it's a new computer should he just take it to the Apple Store he bought it at and have them replace it? Thanks so much.

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 15 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.
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!

My MacBook Pro won't let me mount my external Hard Drive. Just trying to restore my iTunes library.

My MacBook Pro, less than a year old, started acting weird. I backed everything up, took it in to Best Buy, who sent it out to Apple Repair and they put in a new motherboard.
It's running on Mac OS X Version 10.7.4
Now I am trying to put everything back on the computer from my external Maxtor 80GB Hard Drive. MacBook Pro won't recognize the external drive.
I tried Disk Utility. I can see the external drive, and did a repair disk and verify disk. Several times. Each time it says "This partition map seems to be ok."
However, I am not able to mount it, as that option is greyed out and i can't select it.
Also, under the Icon for the external hard drive, it has the Macintosh HD Icon (essentially my computer). I tried to restore this way, didn't work.
I need this to mount, as it has all of my itunes stuff on it; dozens of my sons movies, and my entire iTunes library.
PLEASE HEEEEELP!! HOW CAN I MOUNT THIS EXTERNAL HARD DRIVE? Thank you in advance

Try things in this USB/Firewire faq.

Thunderbolt external SSD won't mount

I'm using the Elgato Thunderbolt SSD as an external hard disk with my 2013 MBP. Since I'm also using a Thunderbolt display, I usually daisy-chain the disk to the display.
Recently I disconnected the Thunderbolt display from my computer without unmounting the external SSD. Since this also disconnected the disk, I got the usual ticking-off ("You should eject a disk before disconnecting it").
However... since then, the external disk won't mount. It doesn't show up on the desktop or in Disk Utility, though it DOES show up ("Thunderbolt SSD") in System Information.
Because the SSD gets warm when it's in use, I think it's still working. I just can't access it.
Can anyone help?

Is the Apple Thunderbolt Display at the END of the daisy-chain? That's where it should be - all other TB devices should be connected first, with the Display at the end of the chain.
As to why you're having a problem getting the TB SSD to work, I'm stumped. It seems as if you've done everything that I would try to do to get everything working... and I'm assuming that you have powered down and unplugged the Display and all other devices for 15 minutes or so?
Just make sure that the Display is at the end of the TB chain - that's really the only advice that I can offer.

Upgraded to Mavericks. Now External HDD Enclosure Won't Mount. Is there a fix?

Upgraded to Mavericks. Now I can't get my external HDD enclosure to mount. A little about this enclosure, as it's not the usual settup . I have four 3TB HDDs in a RAID5 settup. The most unique part is that they are formatted as a Windows NT Filesystem (Tuxera NTFS). Basically, when I set this up, I had to get a lot of info from a Windows-formatted HDD, but also be able to read/write afterwards. It's worked fine for ~ 1 year, but now that I've upgraded to Mavericks, nothing will mount. I ran Disk Utility, where I see the HDDs (I've partitioned them into four drives of varying sizes), but they are greyed out. I tried to mount them, but it says it won't and that I should run First Aid. So I did...tried to "Repair Disk," but it just gets stuck on "Updating boot support partitions for the volume as required." For over an hour it's been on that message.
So, does anybody out there have a fix? I've read several similar posts about people having a hard time mounting and, overall, dealing with external HDDs after upgrading to Mavericks. But nothing seemed to fit my exact circumstances. Lastly, I should mention that I've used both Firewire and USB connections. Both resulted in the same.
Thanks.

I can't help with specifics for your issue, but some general thoughts:
The upgrade and the disk problem may be a coincidence. It would help you if you could verify that the drive still works fine on a windows machine. If you run a windows virtual machine or have a windows pc, or a friend does, verify full functioning that way. If it still won't mount on the mac, try to copy/backup it's data onto the windows machine (maybe another external drive connected to it. You could then scrub the disk in windows, leave it unpartitioned, unformatted. Connect it back to the mac and format it as HFS+ (Mac extended journalled) and transfer the data back to it by sharing the windows machine external drive and connecting the two machines with a network cable.

How do I erase and external HD that won't mount?

Help! I bought an Iomega eGo drive from Amazon. I backed up my MacBook Pro and my work on this drive. Now it won't mount and I want to send it back to Amazon. I tried disk utility, Disk Warrior and plugging it into other Macs. It has firewire 400 & 800 and usb. Nothing from all of them. How d I get my personal stuff off so I can return this hunk of junk? (my 2nd one! I never learn.)
Any help or ideas would be very much appreciated!
Thanks!

Just to add to the previous, if you use "System Profiler" (in your Utility Folder) and look under which ever interface you have it connected through, does the "bridge" in the enclosure itself at least appear, even if the drive itself doesn't? If it DOES, then the problem either lies with the drive or with its connection to external enclosure's "bridge". If even the "bridge"/ enclosure itself doesn't appear then the problem is either with the bridge/enclosure itself, the cable you are using, or the port you are using on the Mac (as the drive doesn't surface under any of three connection methods you can pretty much disregard the last two).
If the bridge is dead, then the only way you will be able to erase the drive is by removing it from the enclosure and putting it in another one (which will almost certainly void any warranty).
If the bridge appears, but the drive does not, then it is probably the drive itself which is dead, in which case you won't be able to erase it anyway, but no-one is likely to bother going through the expensive and time consuming process of seeing what is on it by removing platters etc! Most techs in the warranty departments of major companies like Iomega are overworked, underpaid, and trying to avoid additional work. They just won't be interested in the content. Dead drive, into the bin, onto the next one! As you say yourself, such failures with Iomega drives unfortunately aren't exactly worthy of headlines!
If Disk Utility can "see" it, though, even if it won't mount it, then there may be some other options for wiping data before sending it back.

New partition on external hard drive won't mount

I have an 2TB external drive connected by FireWire to my 24-inch, Early 2009 iMac. I created 2 partitions 1 that is about 35 GB and another that is the rest of the 2TB. The 2nd largest partition mounts fine and is being used by Time Machine for my back up. The 2nd one I wanted to use for a Tech Tool Pro eDrive. However the 35 GB drive won't mount. Well it mounts, but after a few seconds it unmounts itself. This is the message I get as it unmounts itself:
8/18/13 7:18:45.788 PM fseventsd[43]: Events arrived for /Volumes/eDrive after an unmount request! Re-initializing.
8/18/13 7:18:45.789 PM fseventsd[43]: creating a dls for /Volumes/eDrive but it already has one...
8/18/13 7:18:46.039 PM fseventsd[43]: disk logger: failed to open output file /Volumes/eDrive/.fseventsd/00000000030d4f84 (No such file or directory). mount point /Volumes/eDrive/.fseventsd

Any ideas?
I've checked the partition with Disk Utility and no errors.

Chris Johnson

If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Does the volume mount?
Start up in Safe Mode and test.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

External Hard Drive Won't Mount- Need to recover files

Hello Everyone,
I am hoping that one of you fine mac experts may be able to assist ~
Problem: External Seagate FreeAgent Desktop USB external hard drive
won't mount on desktop=ie: no access to my important files.. Please Help!
Details:
External seagate freeagent 500 GB Desktop USB HD ( only 2 months old)
(using for document / file backup-not as a startup disc)
on my Mac G3 350 MZ Blue & White Tower /768 ram/ running OSX 10.1.5 & OS9.2~
~
Problem: Started using the external 500 GB HD 2 months ago -with no problems-until this morning. Tried to double click to open it to access files
and got the "beach ball of death" and needed to restart.
My trusty G3 started up fine, however, the external HD was now
not showing up on the desktop as normal. I troubleshooted -by restarting,
trying different a/c plugs/ different USB ports , ran disk utility..called
seagate -not much help . Seagate said to try the HD on another mac-which I did-
a G5 tower- same problem.
~
The External hard drive will show up in disk utility, but is grayed out.
and when click "mount" same two messages keep showing:
message 1: "a disk attempting to mount as unknown has failed verification or has failed to
mount.please use disk utility to check the disk"
~
message 2- when unplugging and repluggin the usb in-and upon
restart:" you have inserted a disk containg no volumes that mac osx
can read to use unreadable volumes,click initialize to continue with the disk inserted ,click continue"
~
( I really need access to these files- and do not want to re-initialize the HD!!)
I ran Disk Utility /first aid "verify & repair , the following info came up:
Repairing disk "main backup 2007 ".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid key length ( <<<IN RED )
Repair completed. "
~~
Though it said the repair was completed, the "invalid key length" issue
still comes up when re-running disk utility...Hard drive would still not
mount on desktop-even after restarting .
~~~~~
If there is a mac genius out there that can help?- it would be greatly
appreciated. I have tried to call seagate several times in the last several hours-
1st time-they disconnected me after being on hold 10 minutes-2nd call
I was put on hold for 40 minutes ..Finally spoke to someone ( they are not mac users or mac experts!)and he said I would need to send it to Seagate's Data Recovery-... for a fee of course!
~~~
At this point, I am hoping to just get the files and photos off
the hard drive- I heard about Disk Warrior-should I use that and if so
what version?
Thank you very much!

Will zapping the PRAM be of any use in getting the external to mount on the desktop?
Your external Hard drive is already recognized. But it cannot be mounted on the desktop due to its directory damage. You can certainly Zap the PRAM, and it will not hurt anything, but I am skeptical that it will change the situation.
Do you think the Disk Warrior 4.0 cd will even work on my G3 350MHZ running Mac OS 10.1.5?
If you boot from the CD and run it from the CD, absolutely yes. If you attempt to INSTALL it from a download or a CD, probably not.
Have you ever used Disc Warrior and is using it complicated?
I own and use Disk Warrior. You select the drive to be rebuilt, it builds a proposed new directory from the information and file fragments available.
When complete, it will provide a list of problems encountered, tell you what files have been placed in the "Rescued Items" folder, and allow you too look at your drive using the proposed new directory. Your only decision is whether the new directory seems to be an improvement over the old \[in your case, hopelessly corrupted] directory. You then tell it whether to replace the old directory with the proposed new directory, or to abandon its work and leave your Hard Drive unchanged.
Is there a good chance that the ext HD will still have my files on it- or do you think from what I've described that they are gone ?
From what you have described, your files are very likely to still be there. Sometimes in a situation like this, a handful of files cannot be recovered.
My other thought was to take the external HD there and have them try to recover the files.
Make sure you completely understand the costs involved. File recovery using a service like DriveSavers can run into many hundreds of dollars. They are prepared to disassemble your drive in a clean room and replace controller boards and read/write heads to achieve success. Your drive has serious, but not fatal, Directory damage. The Hardware, and most of your files, are likely just fine.

External Hard Drive won't mount - tried Disk Warrior, am backing up as a .dmg...will this work?

Hi Guys,
Hopefully someone can help! Fairly desperate situation here...
I backed up around 700GB of data to an Iomega external hard drive (supplied by the client), using my Macbook Pro...all was fine when I unmounted the drive at the end of the backup.
The client took the drive away and called me to say he mounted the drive in Windows (on a PC), and he was able to work with the files for a time, but now the drive won't mount...
I collected the drive, hooked it up to my Mac Pro, but OSX tells me it can't mount the drive. It shows up in Disk Utility in the sidebar, but not on the desktop...
I tried repairing the disk using Disk Utility and with Disk Warrior, both tell me the disk cannot be repaired...
I am currently making a backup of the drive as a .dmg file, using a program called Disk Drill...it's slow as I expected, but I'm still not sure the .dmg will mount...because surely it's just making a copy of the data exactly, of which some part is not mounting (a mount directory or something???)
Is there any way you guys can think of me somehow taking the data and backing it up onto another disk?
Specialist recovery services seem to think there shouldn't be any problem recovering the data, and of couse, as a costly last resort, that's what I'll have to do, but does anyone know how they may go about doing it? It is something vastly complicated such as a command line thing?
Sorry about the length of this question...just hope someone can help!
Thanks in advance...

You didn't say what format (filesystem type) the disk was.
However, I'd say your analysis is probably correct. Something has corrupted the disk. You can make a disk image copy to the .dmg which will preserve the data, such as it is, but I doubt extremely if it will fix any file system corruption.
Furthermore, if both Disk Utility and Disk Warrior have said the disk is unreadable I'm dubious that anything else will magically repair it and that recovery probably consists of snuffling through the disk block by block.
However if the filesystem is FAT (Windows) there may be other (Windows) utilities that can fix it.
You said you 'backed up the data'. Does that mean you still have the original data on your MBP? Are you trying to recover the client's changes?

External Lacie drive won't mount

I have a older Lacie 160GB LaCie P3 extrenal drive that I can't mount. There never has been an issue with mounting it before in the method described below.
Here is what happened:
I turned the drive on but the firewire was not connected so I turned the Lacie drive off.
I connected the firewire and turned the Lacie on and the (partitioned) drive mounted on the desktop.
I was looking through the files when I got the error message that the drive was disconnected without being properly ejected which I didn't do.
I tried turning the Lacie drive off and on but it won't mount. I get the same flashing light on the Lacie drive that I had before connecting the firewire.
I tried Disk Utility but it can't see the drive.
I tried connecting to my laptop but it doesn't mount there either or show up in disk utility.
Questions:
Any idea how I can get it to mount?
Is there any risk of damage to the data by turning it on and off in an effort to get it to mount. I can hear it running.
Thank you

LIkely (very) your SATA card is fried inside the box for same.
External HD are very easy to diagnose. Bad USB cable (on commercial sold USB drives) almost doesn’t exist anymore.
External USB HD have 4 'parts' (not counting the HD internals)
1. USB cable (never an issue anymore, approaching 100%)
2. HD enclosure.....a plastic or metal box which cannot ever be an issue.
3. the HD itself
4. ....and last but not least is the epicenter of 'weak links' ,.....a SATA card/bridge that is connected to the HD inside the HD box, the size of a stick of gum, with SATA female on one side, and female USB on the other side, containing circuitry for data transfer between the SATA on the HD and to USB on the other.
While these bridge cards are better than they used to be, theyre still insanely unreliable.
There are literally probably MORE than 100,000 perfect external hard drives out there thrown away every year because people assume the "hard drive is bad" when really they could crack open the HD enclosure, remove the HD and put the good HD into a new enclosure.
See this video of the SATA CARD, its at 8:55min. http://www.youtube.com/watch?v=2pS_EDsP2KI
All conventional HD external are nearly 100% like the video above.
See pic below,..a (much larger) SATA card as found inside a typical HD enclosure ($20 ebay)
This is the nasty piece pictured below causing all the "crazy" activity seen on external HD, very odd behaviour, some have called it "haunted hard drive syndrome". Random ejects, random strange vanishing of the HD , especially in mid transfer of data.
the card attached to the TOP of the HD plugs in, that the SATA bridge
