Disk utility crash, external drive won't mount

Hello,
I was performing disk utility on my Toshiba 1T external drive. The disk needed to be repaired, and while it was in progress, I had a system crash. Now I cannot get the drive to mount, it's indicator light is flashing. I suspect the drive needs a data recovery professional now...but I'd like to know if there are any steps I can take with it.

Turn it off and leave it that way.
Professional data recovery is expensive (think thousands). You could try software, a Data Rescue is well regarded.

  • External drive won't mount after plugging in iPhone - MacBook 13'' (2,1)

    Hi Support Crew...
    I have a 13" MacBook(2,1) running OS X 10.6.2. This is a 2 GHz Intel Core 2 Duo machine w/ 4 GB RAM & 320 GB hard drive.
    Today, I had the Iomega drive plugged in via USB, along with my soundcard (MOTU 828mk2) plugged in via FW. This is a very normal setup for me which has been bug free since I bought this computer over 2 years ago. When I plugged in my iPhone 3G via USB I got an error message which comes up when you incorrectly remove a device. This was strange because I didn't unplug anything, I only plugged in the iPhone. The iPhone was playing music when I plugged it in and I had to unplug and plug is back in to get iTunes to recognize it.
    Ever since this happened, my Iomega external drive won't mount. I am able to access it via Disk Utility (and ran the Verify Disk/Repair Disk - everything is "ok"), however I can't access the data on the drive. I really really need the data but of course can't access it to backup.

    When I tried to run Migration Assistant, I just get the spinning search circle and none of the drives come up, just endless searching.
    The fact that I got the "Improperly removed device" error when I plugged in the iPhone makes me think something weird is up and it's not actually the external drive. There is clicking/whining/noise, the drives powers up fine and is recognized by the system but the mount point is now "not mounted".
    Does anyone have any idea how to fix? If you live in SF, I will buy you a beer.

    I meant to say; "There are NO clicking/whining/noise sounds made by the external hard drive"

  • LaCie external drive won't mount on iMAC

    Hi,
    My external LaCie external drive won't mount on my iMAC running 10.6.8 but will mount and show up on my PC as working fine, however I am not able to read the information on it as it was formatted for my iMAC. Therefore it leads me to believe this is a software issue.
    I have reason to believe someone had changed the permissions and prevented the mounting of this external drive (which belongs to me)  so that the contents won't be found on my iMAC.
    How to resolve this issue?
    Thanks in advance,
    Cait

    Cait,
    Please try a SMC reset, it may take 2-3 attempts for it to work. Look over the instructions below carefully.
    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.

  • External drive won't mount. Options?

    Hi everyone. I've used a LaCie 250GB D2 external hard drive for a little over two years with no problems. A few days ago, I bought a Western Digital 500GB drive to serve as my main external drive, so I decided to erase and reformat the LaCie drive, which I had previously partitioned into two volumes, to serve as an archive drive.
    That's where my trouble started.
    I deleted all my files off the drive and then selected Erase in Disk Utility. I checked the option to eight way random write over format the disk for increased security, but that seemed to be taking so long I just quit Disk Utility. I figured since I didn't have any data I was afraid of losing, it wouldn't be a problem.
    The next day I tried to erase it again, but I got an error message that said something about my partition (sorry but I can't recall what the message was; at this point I still didn't think there would be any problem).
    Yesterday night, I tried again to erase and reformat the disk. I selected the option to zero all data because I thought that might solve any hard-to-fix problems. I left Disk Utility running overnight and all day today--about 20 hours in all-- but the progress bar showed no progress. None.
    Now, as of this evening, I can't get the drive to mount at all. When I plug the drive in (and I've tried all three interfaces), the blue activity light starts blinking and I can hear it spin for a little while. It eventually stops spinning but the light keeps blinking.
    I've tried unplugging the drive and plugging it back in. Nothing. I own DiskWarrior, but as far as I can tell there's nothing DiskWarrior can do if the drive won't mount.
    I'm wondering if disconnected the drive while it was running could have caused this problem. I might have done that inadvertently when it was taking so long to format. I figured that might result in loss of data, but I wouldn't think it would render a drive completely non functional.
    I'm guessing the problem is probably a failure of the drive, but the fact that this only cropped up when I tried to reformat it seems suspicious to me.
    If anyone has any suggestions for ways to get the drive to mount or format it, I'd sincerely appreciate hearing them. Thanks.

    Thanks for quick reply. Boy, I really screwed up. I guess I didn't think I could permanently ruin a drive that way. I just assumed as long as the drive could spin and wasn't going bad, you could always reformat it.
    Just so you know, I let my iBook run untouched for literally 20 hours in the zero out erase mode, but the progress bar showed no progress at all, so I think the drive must have already been broken by that point. I was prepared for it to take a day or more, but with no visible progress in 20 hours it would have taken weeks.

  • External drive won't mount- which software is best for data recovery?

    Hi,
    My external OWC drive won't mount to the desktop. It is visible in Disc Utility, but can't be manually mounted from there. Verify and Repair disk functions state that the disk appears ok (log below):
    Verify and Repair volume “OWC Mercury Elite AL Pro mini”
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking multi-linked files.
    Checking Catalog hierarchy.
    Checking Extended Attributes file.
    Checking volume bitmap.
    Checking volume information.
    The volume OWC Mercury Elite AL Pro mini appears to be OK.
    Drive lights up and spins. No weird sounds, just won't mount.
    Not everything on the disc was backed up before the problem occurred. It's still under warranty with OWC, but I'd like to attempt to recover the data before sending it in for repair/replacement. The OWC tech on the phone said he's never seen this specific problem with this drive.
    I'm thinking Data Rescue 3 would be the best software to try, but does anyone know of any other options to try first?
    Thanks!

    JohnDoe2009
    I concur with the previous poster that if Disk Utility found no problems running TechTool Pro, Drive Genius or Disk Warrior might get it going. If you don't have any of those you could try
    • Download and install Applejack
    • Restart computer holding down Command + S
    • When Command line comes up type in
    +applejack AUTO+
    Let is run all five functions.
    In terms of Data Recovery
    DataRescue 3
    Virtual Lab
    FileSalvage
    are all excellent tools, and all offer a demo version.
    Dr. Smoke's FAQ Data Recovery offers excellent tips on how to do it.
    Good luck.

  • External drives won't mount after running repair permissions

    None of my external drives will mount after running disk permissions. Drives work fine on my mbpro.
    None of the external drives show up in disk utilities...
    I've try shutting down and unplugging computer. even mini zip drives won't mount.
    I'm running 10.4.11
    PPC G5 2.3Ghz
    Thanks for any help..

    Repairing Permission only deals with installer receipts and system components. Not with mounting or accessing hard drives.
    Have your run Apple DU First Aid? Disk Warrior? Only use latest version for your OS.
    Are you trying to clone your system to external and then repairing permissions? trying to boot from them?
    If cloning, make sure the "Ignore Ownership" flag is unchecked before cloning (but do repair permissions on external drives you intend to boot from, such as a Firewire drive).
    What type of cases and interface are these?

  • After SN install can't launch Disk Utility from external drive

    I recently upgraded 10.5.9 to SN on my white Macbook. First I used Carbon Copy Cloner to clone the old drive onto the replacement drive in an external enclosure. Then I swapped drives so that the new drive is now the internal drive and the old drive is in the enclosure. I then upgraded the OS on the internal drive via SN installer on DVD.
    Now when I start from the external drive in OS X 10.5.9 and try to launch Disk Utility from this drive I get a weird error message that "Disk Utility can't be launched because it's incompatible with this architecture." The only things I can think of is that Snow Leopard installs something that globally effects all perhipherals (like new disk drivers?), or that there is something in the enclosure's USB bridge which is causing this, or that installing Snow Leopard breaks the PRAM for older versions of OS X. Tech support for the enclosure vendor tells me there is nothing in the enclosure's USB that would cause this. Any insights into what's happening appreciated.

    Thanks for response. Ah, that's it. I was trying to launch it from the applications folder I had dragged to the dock, which was done while running Snow Leopard. That's why (duh!) all the application icons were slashed out. : |

  • External Drive Won't Mount

    My external backup drive wont mount automatically as it used to with my earlier ibook. I have to re-boot computer to get it to mount. After that it functions properly until the next time I turn it on to do a backup.
    I am wondering if there is something in the formatting of this drive which is causing this? I have formatted it a few times since this started to happen but obviously without fixing the problem

    Further Details:
    1) After normal use of computer connect and turn on external drive. Drive does not mount.
    2) Re-boot computer and turn on drive. Drive mounts.
    3) Eject drive. Turn off drive. Turn on drive again - drive mounts.
    4) Run SuperDuper backup. eject drive. turn off drive. turn on drive - drive mounts.
    Thus, it seems (see (1) above), something in the normal use of the computer (not an artifact of the superduper backup process) over a period of time affects the system such that the drive won't mount again.

  • External Drives Won't Mount with Mavericks

    My external drives will not mount with Mavericks. They did for a while but I noticed that they stopped doing so a week ago or so. I have a drobo raid, hitiachi drive in an external case and a WD Passport. The drobo goes to sleep, the Hitachi external spins and the WD flashes like its being read.
    None of the drives were mounted when I loaded Mavericks and, as far as I know, they've not been erased. They did  mount for a few weeks but doesn't look they have since the beginning of November.
    I have a brand new 2013 MBP 15" Retina with 750 GB SSHD, 16 GB ram and a 2.7 GHz i7. The drives are all connected via one FW800 through a Thunderbolt dongle.

    I eventually gave up. I will probably get another card at some point but it probably won't be a SIIG card. Even though they are recommended by digidesign I just doesn't seem to want to work with my G5. Maybe it's some kind of weird software conflict blocking the functionality of the card? Don't know. Two cards in a row were non functional. Something is gummin up the works and the PCI slots work with the other cards I have. The only thing I did not try is plugging in the optional power connection to the FW800 card, which is supposed to be optional. I called SIIG and they had no idea what the problem was and they also said that the power plug would not make a difference for the problem I was having. Anyway, I'm gonna keep monitoring posts to this cause I'd love to hear the answer.. but I'm throwing in the towel. Good luck to the rest of you still trying to solve the riddle.

  • IPod used as external drive won't mount

  • External drive won't mount on desktop or disk utility

    iMac w/optical drive, running 10.6.8
    Using a 2 TB Seagate Backkup drive for Mac for Time Machine backups. Time Machine notified me that no backups had been made for 22 days. Drive icon does not show on desktop and is not listed in Disk Utility. Tried unplugging/plugging power and USB cable without success. I had shut down the computer before leaving for vacation (about 22 days ago), but am pretty sure I did not move the drive icon to trash. Could this be the basis for the problem?
    How do I get this drive mounted again?

  • External Drive won't mount to Time Capsule, Unable to Archive Disk

    I use my Time Capsule as a network drive. I do not use it for Time Machine back-ups.
    I need to backup the data on my Time Capsule disk. As far as I'm aware, the only way to back-up a Time Capsule disk is to connect an external drive to the Time Capsule's USB port; open AirPort Utility on your computer, navigate to the "Disks" tab, select "Archive Disk..." then choose the external drive in the "Destination" drop-down menu.  The problem is, my G-Drive mini doesn't seem to power up adequately when connected to the Time Capsule to mount. I can hear the drive making a quiet clicking noise but nothing else happens. The G-Drive never becomes visible under the "Disks" tab in Airport Utility.
    The external drive is newly formatted as Mac OS Extended (Journaled) in Disk Utility. To connect the G-Drive mini to the Time Capsule I am using the USB cable that came with the G-Drive mini (port on back of drive says USB2.0). To power the G-Drive mini I am using a 12V, 2A AC Adapter (DC IN port).
    The same configuration connected directly to my MacBook Pro mounts the drive without any trouble.
    My hardware specs are: Time Capsule version 7.6.4; G-Drive mini GDM4 500 X; MacBook Pro 2.5GHz Intel Core i7
    My software specs are: Lion OS 10.7.5; Airport Utility 6.3.1
    Any help is much appreciated.

    I don't have a G-Drive here to test, but 3 other USB drives show up just fine when I test with them connected to the USB port on the Time Capsule using a powered hub.....all at the same time or one at a time.
    You might want to ask G-Drive support if their firmware supports a network USB connection.....not just a local or direct connection on a computer.
    Otherwise, I'm stumped.

  • Re: WD External drive won't mount

    Hi
    I have just experienced this issue today. I have gone through all the threads here and searched various other forums but haven't been able to come up with a solution yet. I might be missing something.
    I'm running a 2011 Mac Book Pro OS 10.9.5 Maverick.
    I have a 1TB My Passport for Mac that's a couple of years old now, it is used for my time machine backups. Using WD Drive Utilities, I can run a smart status scan which passes, the quick drive test Cancels.
    In disk utility it appears on the left but is greyed out. The info that is provided tells me it is: (bare with me I'm using my iPad as my MacBook Pro won't allow me to Ely to this forum, an issue to tackle after this one)
    type: partition
    mount point: not mounted
    owners enabled: no
    journeled: no
    disk utility is the only place I can see the drive appear. I don't Have the ability at the moment to connect the drive to a windows pc. I have also tried using disk utilities repair and erase options with no luck. I have tried using terminal and activity monitor several times as previously mentioned in this thread but again no luck but may have missed understood the directions.
    I would simple reformat the drive but suspect because it's greyed out its why I can't.
    any help or directions would be great?
    thanks for your time and knowledge.

    Read all the threads on this.  I am similar to Phoenix86.  I force quit fsck_hfs a few times when I started the bad drive but that did not prompt anything in finder. Currently I am imaging the drive to see if that gives me access to my files on the external.  Last night I did a restore, but the (brand new) drive it saved to behaves just like the bad one that disk utilities so still can't access the files since that one won't mount either.  I also tried a few things in terminal that someone else suggested, but like this repair:
    fsck_hfs -r /dev/disk2s3
    ** /dev/rdisk2s3 (NO WRITE)
    Can't open /dev/rdisk2s3: Permission denied
    I don't know what to do with this message... 
    I feel so stupid, like the files are right there, but I can't get to them to copy them over.  I can hear the disc spin, and it can eject from disk utility, can't open, not even in volumes directory. 

  • WD External drive won't mount

    Hello everyone! I haven't been here in a while because I just haven't had any Mac issues. Now I do.
    I have a 1 TB WD external HD that won't mount. I connect it via firewire to an Old G4 Sawtooth running OS 10.5.8. My mac sees the drive, it just won't mount. I've also tried to mount it via USB, but again, my system sees the drive, but won't mount it. I inadvertantly disconnected the firewire cable, which I didn't realize for several hours. I reattached the cable, tried to mount it, and nothing. I ran disc repairs, and Disc Utility actually told me the drive was successfully repaired. Again I tried to remount it, but nothing. I repaired permissions, and this didn't work. I've tried different cables, and this doesn't work.
    I don't have another Mac to connect it to, so I don't know if this would work. Here's where things get a little wierd, but interesting. I connected it to my PC laptop, and it mounted. Now, this is a drive that was formatted Mac OS Extended (Journaled) on my G4, so I have to use Mac Drive so my PC will recognize and mount The Drive. So My PC sees The Drive as Mac OS Extended, and mounts it. All files are in tact, and the drive runs normally. This is a music drive and it plays normally on my PC. Meanwhile, if I try connecting it back on My Mac, the name of The Drive randomly changes from 931.5 GB WD to 931.5 GB WD My Media Book. I believe My Media Book is the factory name of The Drive before OS formatting. The Volume name remains the same on my G4 each time I've tried to mount it.
    I do have another identical drive that mounts from all the bus ports on my G4. Any ideas here? Can I get my Drive to begin mounting on my G4 again? Any and all answers are appreciated.

    Terminal List. disk4 is the malfunctioning drive.

    I've read that WD uses crappy chipsets in their external drives. I'm wondering if the chipset is suspect here? Just not sure. I did discover that I can clone the drive from my PC as an exact Mac OS Extended (Journaled) drive, and my Mac doesn't even know the difference. I've also read that I can initialize the drive, and reinsert the drivers, and the drive should function normally. Interesting, huh? Well, let me know what you come up with BDAqua. And again, many, many thanks.
