External HD/D not mounting - not sure what to do!

Hi there,
Last night I encountered a problem with my seagate FreeAgent external HD/D.
I right-clicked on the desktop icon to eject it as per usual and once the icon had vanished I pulled out the USB cable. However, I then got a message saying that I didn't eject the device properly and might have lost data blah blah etc.
When I plugged the external drive in this morning I found that it wouldn't mount. I am in a state of panic at the moment because it is almost 150gb of data that I really did not want to lose! I read in one of the previous threads that this is a common problem amongst macs but I wasn't able to discern if this was a permanent error and if it means my drive is shafted...
I ran disk utility and this is what it came up with :
Verifying volume “disk1s1”
Checking HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid node structure
Invalid B-tree node size
The volume needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I tried to repair it using disk utility but it wasn't able to do it. I am now using the demo of Data Rescue II to do a thorough scan which will take several hours but I'm wondering what options I have. Are there any other mac tools I can use? I am a total newbie when it comes to macs having only made the transition from PC to Mac several months ago and I don't know what tools I can utilize to fix this problem, if it even CAN be fixed.
I really hope someone can help me!
Cheers,
James

Hi James,
The 'Repair Disk' function within Disk Utility needs to be run several times. Presumably you only did it once. Sometimes, it can take 5-6 times before you get an all clear; sometimes a little bit more. If that still fails, then you'll need more 'stronger' third party utility software to scan the disk and make any necessary repairs (DiskWarrior, TechTool Pro etc).
I read in one of the previous threads that this is a common problem amongst macs...
I have 8 external hard drives in total; three of which are mobile firewire hard drives that travel with me wherever I go. I have never had an issue with any of them. There was one occasion when I plugged in one of the external HDs immediately after buying it and it refused to mount; turned out to be a faulty hard disk so it wouldn't have mattered whether it was connected to a Mac or a PC.

External drives won't mount. not even virtual! PLEASE HELP!

I'm fairly tech savvy but I'm completely lost on this one.
I have a G4 867 running OS 10.4.8 Sometime after updating and running smoothly for sometime my computer stopped recognizing external hard drives.
I have two different firewire drives and a USB jump drive and an iPod and none of them are recognized anymore. They do not mount and do not show up in disk utility. However one of my firewire drives is an older system drive and if I have it on before start up I can boot off of it and it works fine. I'm not sure but because of this it really seems like a software issue.
Does anyone have any suggestions? I really want to update my iPod (it will charge but not mount) as well as use my other drives. As far as I can tell it is not directly related to 10.4.8 because it worked fine in 10.4.8 for weeks and there is nothing else I can think of that I added to the system that might affect it. Please help me..
Thanks,
Dustin

It might have something to do with your kextcache. Try moving the following three items to your desktop and perform a shutdown (not a restart)..
/System/Library/Extension.kextcache
/System/Library/Extensions.mkext
/System/Library/Caches/com.apple.kernalcaches/
Be careful when wandering into the System folder and folders therein.

the only thing that was a little different is that it wants to only copy those files to the desktop so I had to delete the originals, but it works 100% now.

Mirrored RAID not mounting/not showing as RAID (Disk Utility)

I have 2 Lacie Firewire Disks set up as a mirrored RAID (created by Disk Utility). I've been using this setup for about a year with no issues. But today I tried mounting the RAID and I got this msg twice (one for each drive)...
"Disk Insertion - The disk you inserted was not readable by this computer."
It then asks if I want to Initialize, Ignore or Eject. If I leave this msg up for a bit it eventually just goes away. But the disks never load.
I opened up Disk Utilities to check and see if the drives were listed and they are, but the RAID is NOT listed. All of the first aid options are greyed out. I tried to mount each disk but they will not mount, I assume because the RAID info has been lost?
Is there a way for me restore the RAID or at least get my info off of the drives? They contain a large photo library that cannot be replaced.
Powerbook G4 Aluminium 1.33gthz Mac OS X (10.4.7)

I never technically fixed the RAID. I used the program Data Rescue mentioned above to look at the drives and pull my data off of them. What I found was one of the drives was in perfect order, and the other drive had stopped recording data MONTHS ago. Basically the RAID became un-paired and stopped working correctly, and only one of the drives was saving the data. It freaked me out at first because the drive I decided to recover first was the one that was missing data. But I then looked at the 2nd drive and it had all my data on it, and I was able to recover it.
Anyway, Data Rescue worked perfectly. Now I just have the drives running independently. But I am staying away from the apple software RAIDs for now, as I did some reading and they seem to not be so trustworthy.
Also, Data Rescue takes quite a bit of time to pull all your data off, especially when you have a couple hundred gigs of data. Hopefully this helps.

Macbook Pro 2012 HDD not mounting/not showing in disk utility

I opened the macbook to find all apps freezing, nothing would work. So i did a hard shutdown and restarted the machine, and when it booted i just got the flashing folder icon. I re-booted into internet recovery, and went in to Disk Utility and found that the hard drive was not mounting and showing in there. I swapped the hard drive with a spare SSD and it worked fine, so it's not the cable. Also when i boot up, i can hear the hard drive spinning so its not completely dead. I have booted it up as a target disk with the iMac and it still will not appear. There's some photos and other bits that i really want to recover from this drive. Any advice?

Okay, so i have held off going to an Apple store because i wanted to recover the data from the hard drive before repair/replacement. I fitted a 120GB SSD drive which worked fine until today when i opened it up and the same thing occurred. It would seem that it is not the hard drive that had a problem, but perhaps a software issue. I managed to boot up once after the crash and the error report listed a kernel panic as the root of the problem. Here is the full report, which i also got the first time it happened...

Any help or ideas what may have caused this? I can't boot into safe mode, and i cannot mount the drive to repair in disk utility. Is there a way to resolve this myself?

HT204088 My company purchased a macbook air with cash in march. I need the billing note for accounting but im not a 100% sure what store in New Jersey i bought it in. I have the Mac address of the computer, where can I send it to get an accounting note?

The question pretty much says it all. What can be done?

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
Take the Mac's serial number, not a MAC address, to one of the stores and perhaps they know how to find what you need on Apple's retail servers.

CD stuck in combo drive – not mounted / not recognized, so cannot eject

A CD which had been recognized and could be played in iTunes was in the combo drive when I rebooted. After reboot the CD was not recognized/mounted, and was not visible in Finder, iTunes, or DiskUtility (therefore, it cannot be ejected).
I rebooted with the mouse button held down but nothing happened. Then I did drutil eject, trying it a few times in succession, but nothing happened.
At no time after the original reboot has there been the slightest clicking or whirring noise from the combo drive. Evidently the system 'thinks' the combo drive has no disk inside it.
I haven't tried to go into single-user mode to try to eject it from there. (Incidentally, I have conflicting methods on how to enter single-user mode – is it cmd-s or cmd-opt-o-f ?) Before I try that, my question is that given that I know a good CD is inside the combo drive, is there any command (in Terminal) that would make the system force it to mount?
Thanks for any info.

HI,
Before I try that, my question is that given that I know a good CD is inside the combo drive, is there any command (in Terminal) that would make the system force it to mount?
Try the suggestion here: http://forums.macosxhints.com/archive/index.php/t-4446.html
To eject the CD. Try launching iTunes, then Quit iTunes then press the Eject key on your keyboard.
And, instructions here on how to Startup in Single User Mode

Apple superdrive not working on iMac , will not mount , not recognized

I bought a new superdrive and it was not detected on my iMac. The internal drive was failed , I found a solution here.
http://www.hardturm.ch/luz/2011/10/how-to-make-the-macbook-air-superdrive-work-w ith-any-mac/

The Apple USB SuperDrive only works officially on Macs without a built-in SuperDrive (the MacBook Air, Mid 2011 and newer Mac minis, the Late 2012 iMac and the MacBook Pro with Retina display). As your iMac has got a built-in optical drive, it doesn't work by default, but as you said, that workaround makes the Apple USB SuperDrive work.
Anyway, if you have a Mac with a built-in SuperDrive and the SuperDrive gets damaged, I recommend you to buy a different external optical drive. The Apple external optical drive doesn't have a good reputation because it often fails and it's much expensive than other external optical drives

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

ORA-15001: diskgroup "FRA" does not exist or is not mounted

Dear Experts,
We noticed the error "ORA-15001: diskgroup "FRA" does not exist or is not mounted" on the 2nd node of our 4 nodes RAC database system.
During this weekend, we moved our system to a new data center. After the move was done, we were able to bring up the 4 instances around 3:00 AM. However, 4 hours later (7:00 AM), OEM Grid control alerted us with "archival error" on the 2nd instance. From our investigating, we saw the FRA was dismounted. Below is the oracle alert log file (For secuirty reson, the SID is modified):

ORA-15001: diskgroup "FRA" does not exist or is not mounted
ORA-15001: diskgroup "FRA" does not exist or is not mounted It is my understanding, that Oracle will automatically mount the diskgroups on the ASM when the instances are started. In our case, all other diskgroups are started OK but not the FRA diskgroup. Is this a bug with FRA where FRA can not be automatically started up after recycling the instance? Did anyone experience the same situation? Can someone advice?
Thanks!

Hello,
We are running oracle 10.2.0.2.
Which section of the alert log file for +ASM2 we need here? I will paste it here the ones when "alter diskgroup all mounted" started at 3:00 AM all the way upto 4:00 AM on Saturday, Feb 7:

External hard drive not mounting - what's happening?

All of a sudden one of my external firewire drives is not mounting, but that's not all....
it's not showing up in disk utility, not showing up in system profiler, not showing up on desktop, not showing up in finder, not showing up in Disk Warrior, and not showing up in TechTool.
When I turn on the power, it seems to spin up but doesn't mount. No usual noises either.
Could it be a faulty controller board on the enclosure?
Any suggestions?
Really hope to figure this out, cause it has my entire itunes collection (500gb) on it.
Thanks in advance.

First, try another FW drive or device in your computer to be sure that FW is working.
If you have more than one FW port, try the drive in it.
Change FW cable.
Try the external HD on another Mac (do not use a PC!!!)
If none of above works, it's most likely the logic card in the enclosure, and not the external HD. I believe your data are OK.

How to make external devices (like iPods, etc.) NOT mount as connected drives when plugged in via USB to a Mac?

If I plug my iPod (or a thumb drive or whatever) to my Mac's USB port, the device appears as a icon representing a connected drive on my Mac's Desktop.
This is normal, expected behavior.
HOWEVER, in some cases, I'd prefer that the device not "mount" as a connected external drive.
With thumb drives or external USB drive, of course, I want them to "mount" so I can transfer files on or off them -- that would be the only possible reason to connect an external drive like that.
But with other Apple devices like iPods or iPhones, there are TWO possible reasons to connect them to a Mac: either to "sync" them or transfer files on/off them; OR, to simply recharge the device's battery. (Or, both sync and recharging functions at once.)
For those people who use their Apple devices in ways that require transferring files (i.e. most people), then having the device "mount" as a connected device is a desirable behavior.
But in my circumstance (and I bet there are a lot of people in a similar circumstance), I have no need or desire to transfer any data to or from my device every time I plug it into my Mac: I'm plugging it in SOLELY to recharge the device's battery.
Specifically, in my case, I have a 6th-gen iPod Nano, and I use it exclusively as an FM radio and a pedometer. I don't have any mp3s or songs or any other external files loaded on it, nor do I plan to add any in the future.
The only reason I ever plug it into my Mac is so that I can recharge the iPod's battery.
But the "problem," which is a minor one I admit but a problem nonetheless, is that every time I connect the iPod to the Mac, the iPod appears as a "connected drive" icon on my Mac's desktop. Which means that I'm not supposed to just unplug the iPod when I'm done -- first, I have to find its icon on the Mac Desktop, and then drag the icon to the Trash, to "unmount" it -- and only then can I freely unplug the iPod without getting an error message telling me that I shouldn't just disconnect connected drives without first properly unmounting them.
This would be bothersome enough if I only had to do it once per connection, but in the case of the iPod Nano, there's no way to tell how recharged it is while it is in the act of recharging, so that to see if I'm "done," I have to unplug it, check the battery status, and if it's not fully charged, re-plug it back in. So that each time I recharge it, I often have to unmount the drive several times, depending on how impatient I am.
There has to be a way to prevent the mounting of the drives of devices that one is connecting simply for the purpose of recharging. But how?
Strangely, I also have an old iPhone, and when I plug that in for recharging in the same way, it DOESN'T appear as a connected drive on the Desktop. I'm not sure how I managed to do this, but long ago I must have changed some setting or preference for this to happen. And by now I've forgotten what I did.
I'd prefer that I could change the "mount/don't-mount" setting on a device-by-device basis -- i.e. make it such that this particular iPod doesn't load, but perhaps a different iPod would load -- but if that's not possible, then is there a way to stop ALL iPods and iPhones from loading as connected drives when plugged in?
(I'm not talking about appearing as connected drives within iTunes -- I'm talking about appearing as an icon on the Desktop in the Finder.)
And please don't tell me to just buy a wall charger! I prefer to recharge off my computer if possible, using the charging cord that came with the iPod.
I presume there's some simple setting to toggle this on or off, but I haven't yet found it. Any clues would be appreciated. Thanks!

Well, I already know about that Finder Preferences option, but that is not what I'm looking for. Why not? Because I still need CDs and DVDs to appear on the Desktop and mount properly! If I uncheck the "CDs, DVDs and iPods" option, then I lose the ability to access CDs and DVDs, which creates a whole new problem for me. What I want is to not mount iPods only -- actually, what I really want is to not mount this particular iPod -- but if that level of specificity is not possible, then I want to exclude just iPods from mounting, without also condemning CDs and DVDs (or whatever) to invisibility.
Also, I was confused by the way the Preference is worded: It says "Show these items on the Desktop," with a series of options to check. But this phraseology seems to mean that the unchecked items will still "mount," they simply won't appear as Desktop icons. One would still have to "Eject" them using a menu command, rather than dragging the icon to the Trash -- right? Or am I mistaken, and is the Preference Pane simply badly worded, and when they say "Show these items on the Desktop," what they really mean is "mount these external devices as connected drives." So that if a category is unchecked, then they won't load as external drives at all?
But if so, then what purpose could possibly be served by inserting a CD or DVD that is not recognized by the computer? And if it isn't recognized, then it would seem that there would be no way to ever Eject the CD or DVD disk. Right?
Thus, if I uncheck that Finder Preference box you suggest, one of two outcomes will result:
-- Either CD, DVDs and iPods are still mounted, they just won't appear as icons on the Desktop; but they would still need to be Ejected via a menu command, which doesn't solve my problem.
-- Or, CDs, DVDs and iPods are not mounted or recognized by the computer at all, which means that if I insert a disk into the disk drive, it will get stuck there forever, since there's no way to Eject it, since the OS doesn't recognize that it's even there. Which is thereby a new problem.
Either way, I'd have a problem! Or...? Clarification, anyone?

EXTERNAL HARD DRIVE NO LONGER RECOGNIZED, DOES NOT MOUNT

Hello everyone, this is not necessarily a mac mini issue
last night was working on my mac mini (intel 2007), it froze up, couldnt even restart, so i held the power button (hard reset i guess)
it came back on but then would NOT recognize my external HD, (which is an iomega mini max 1TB)
perhaps this was considered by my mac as "not ejecting or putting the disc away properly "
i did a ton of research (here and elsewhere)..found various hints/fixes but nothing works so far
i tried using different cables, firewire, usb..ran hardware test...zapped the pram....tried it on my ibook (which also does not recognize it)...turned the hd off and on...
i unplugged everything, power to mac, all cables.. left overnight...tried again with no luck
restarted, powered down...nothing
tried finding the the external hd partitions in "/Volumes" to trash. there was ONE of the partitions there, which i trashed - no luck (i had 3 partitions on the external hd)
was going to swap the hd to another enclosure, but the mini max hd wont fit it/work
disk utility doesnt see it
i tried a few things with terminal - nothing
i am unable to open firmware (via commandoption+OF, as this is an intel)
it doesnt seem to be a problem with the firewire port, as that port recognized my video camera
im pretty sure the HD and my data is fine, its just that my mac doesnt recognize it. its like its already "on" or "mounted"
it cant find the path or map or something like that
in system profiler it comes up as:
"Unknown Device:
Manufacturer: Unknown
Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec
Connection Speed: Up to 400 Mb/sec"
any ideas? why would force shutting down (by holding the power button) cause my mac to no longer recognize the external HD?
i have NOT tried "discwarrior" or norton. trying to avoid having to pay $100 and i read that others with this problem bought discwarrior, which didnt see it or help
i did try something called "total recall" by virtualab - it did NOT see the external HD
and as i mentioned above, disk utility does not recognize it
ok please let me know, i could really use some help here
i do usually backup to dvd's but not everything..also did a ton of work recently that was NOT backed up
hope to hear from you soon!!!
thanks in advance, andrew

hello, i dont have a UPS but have it connected to a power strip
what might this mean?
btw - when this first happened (3 days ago) i used disk utility/first aid to examine my mini, it PASSED
yesterday i thought what the heck, ill run first aid again
and this is what i got:
verifying volume "mac mini"
checking HFS plus volume
checking extents overflow file
checking catalog file
incorrect block count for file AbletonTmp-0001
(it should be 1 instead of 0)
1%)
checking multi-linked files
checking catalog hierarchy
checking extended attributes file
checking volume bitmap
checking volume bitmap
or repair",0)
checking volume information
volume header needs minor repair
the volume mac mini needs to be repaired
error: the underlying task reported failure on exit
1 HFS volume needs repair
it wasnt able to fix it while booting/running off the mini so
i then ran disk utility on the OSX install disc and was able to fix that problem
but alas, no luck with the external HD, still not recognized
the AbletonTmp-0001 makes sense because that was one of the programs i was running when it crashed
i was hopeful that fixing that problem would help.
ive been through quite a few crashes and restarts like that, i wonder why this time it caused such a serious problem
i would imagine there are a ton of people who have to force a restart or dont eject the HD, or unplug it, etc
i wonder why there isnt an easier/better way for a mac to deal with an external hd/flash etc. are pc's as sensitive with ex hd's?
ive had to tell new mac owners again and again -"no! you have to eject it first!"
ok well thanks in advance for any further advice/help
it means a lot to me, so thank you!!

External Hard Drive not mounting on bootup

I have a USB2.0 Hard Drive formatted with ntfs, which holds my music. I have an fstab entry for it using ntfs-3g and I can mount it fine after booting up. But the drive doesn't automatically mount like it should. It looks like the system is mounting the fstab entries before it is finished detecting my external drive. Anything I can do to fix this?

fwojciec wrote:I let my external ntfs drive be mounted by hal - I have no entry for it in /etc/fstab. In order to have it mounted with read/write privileges I had to create a hal policy like this wiki page describes: http://wiki.archlinux.org/index.php/HAL … ntfs-3g.29
I'm not sure if this solution is what you're looking for though...
I actually tried using hal to do it and it didn't work right for some reason.

External Hard drive will not mount on Macbook Air (mid-2011) OSX 10.9.4

Hello Everyone!
Needs some help resolving this issue. External hard drive (Toshiba v63600-C) will not mount anymore on my mothers-in-law's macbook air. She notice this problem starting on the Aug 6th. You can see it in the Disk Utility but is not mounted. I can get the her ext hard drive to mount on my Macbook Pro with no problem. I also tried my personal ext hard drive (Seagate) on her Macbook Air and it will not mount. Not sure what is going on here. Any help is appreciated in resolving this issue.
Disk Utility
Mount Point : Not mounted Capacity : 1 TB (1,000,096,367,104 Bytes)
Format : Windows NT Filesystem (Tuxera NTFS) Available : -
Owners Enabled : - Used : -
Number of Folders : - Number of Files : -
Actions Taken So Far:
1) Confirmed "external disk" is selected under Finder's Preference
2) Reset PRAM
3) Ran Verify Disk and Repair Disk under Disk Utility with no change.
4) Tried manually mounting disk in Disk Utility but get "Mount Failed" error

You may believe this is Apple's problem but I just like Baltwo have had absolutely no problems with any of my Firewire drives in Lion. So unless you can come up with much stronger evidence to the contrary, I doubt that your feeling are going to carry any weight at all.

External hard drive that not mount

I let my external 1TB WD Elements fall down and disconnect and after that I can not mount it anymore.
I am on 1068 17" MBP.
Under "System Profile" there is a connected HD:
but on "Terminal" it is not listed:
"Parallels Desktop" can see it but not mount:
Please, help me !

Hi,
As you've discovered, listing a HDD and mounting it are two different things. I think it's clear that the HDD is, for all intents and purposes, dead. Either the controller board and/or seek/write heads and/or the platter/s itself have been damaged in the fall. I'm sure that's not what you want to hear, but I suspect it's true. If so, there is no easy way to resurrect it. It's slightly possible a very expensive data recovery service could extract some data, but I wouldn't count on it.

External HD/D not mounting - not sure what to do!
