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"

  • 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?

  • WD external drive won't mount after OS upgrade

    After updating to latest Lion my WD 2T external drive wonlt mount. Actually it will mount momentarily and then disapear. I have loads of data on there (pictures, etc) that I do not want to lose.
    There is a firmware update on the WD site that is supposed to address this issue, but it very clearly warns to back up your data before updating the firmware. If I can't mount my drive how can I back up my data?
    Has anyone else had this problem and succesully fixed it?
    Thanks for any help!

    I think I have fixed it (fingers crossed).
    I unistalled my virus protection, turned time machine off, verified the disc and remounted it.
    So far, so good. It has styed mounted for a coupel of hours so far and all the data seems to be there.

  • External Drive Won't Mount After Power Failure

    I was in the process of erasing a hard disk that was repeatedly not behaving correctly when the power went out last night. Now it won't mount at all, though another external disk I have daisy chained to it will mount. I have tried unplugging it (both the firewire cable and power) and it still won't mount. Any ideas? Thanks.

    Actually, the opposite is true; you can't reformat a mounted volume. If the device isn't showing up in the left hand side of Disk Utility at all then you've probably got a hardware problem.

  • 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

    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.

  • Maxtor External Drive Won't Mount!

    Here is my problem.
    We got a Maxtor One Touch III 1 TB external drive. I loaded about 850 GB of media onto it, passed it off to my partner to continue to edit our video project. Everything was running fine on my macbook pro 2.2 core duo. He edited for a day on his macbook 1.83 core duo. Said everything was fine.
    That night he shut the machine down without unmounting the drive. He said the drive kept blinking so he shut it off. In the morning he tried to connect the drive to a g4 tower running 10.3.9. (I never realized he was so tech-vapid). He said the drive wouldn't mount. Then he moved it back to his macbook. Still wouldn't mount. Now it won't mount on my macbook or any machine. He then wonderfully told me he once had the same problem with a G-Drive 500 GB external. Wouldn't mount after switching it to his g4 and back. G-Tech told him the drive was dead so he sent it back. Maxtor told us this drive is dead, but I just think it sounds fishy.
    It is still spinning, but there is no light on. Have tried every different kind of connection and updated drivers, same result. A friend said if it got unintentionally unmounted it might take the OS hours to fix it up because it's a RAID 0, suggested leaving it connected for a few hours and see what happens, but that happened once with my G-RAID and it didn't need time to fix itself. I am stupid for buying a maxtor it seems, but it doesn't change my dilemma.
    Someone help.

    Check the /Volumes/ folder for a broken alias to the disk. The folder is invisible so you need to use the "Go" menu to open it.

  • Hard Drive Won't Mount After Repair by Second Computer

    I have an G4 Cube with OS 10.2 on the internal hard drive (which is full) and OS 10.4 on an external La CIe hard drive (that I use as my main OS). The external hard drive accumulated serious damage that couldn't be repaired by Disk Utility on the internal drive. My copy of DiskWarrior X would not run under OS 10.2 (10.4 was required) and it wouldn't boot from the CD either So I connected the external hard drive to my second computer, an iMAC running OS 10.5. (Unfortunately, I disconnected the external hard drive when the computer was off instead of ejecting the drive by dragging it to the Wastebasket.) The external drive mounted and DiskWarrior easily constructed a new directory, defragmented the files, and eliminated all of the damage on the external hard drive visible to Disk Utility. However, when I reconnected the repaired external hard drive to the G4 Cube, the drive wouldn't mount. Privileges were repaired on both computers with the external drive connected without helping. Being repaired while connected to a higher OS or perhaps simply being connected to a higher OS seems to have left the LaCie external hard drive in a state which couldn't be mounted by an earlier OS.
    Following this hypothesis, it booted the G4 Cube from the OS 10.4 Installation CD while the LaCie external hard drive was connected. When I cancelled installation of OS 10.4, I was asked to choose a start-up disk AND OS 10.4 WAS NOW MAGICALLY AVAILABLE ON THE EXTERNAL DRIVE. Simply starting up from a more advanced OS allowed the hard drive to mount.
    Shockingly, when I restarted from OS 10.2, the external hard drive was still mounted. Whatever was preventing the drive from mounting was a TRANSIENT STATE, not backwards incompatability.
    POSSIBLE LESSON: If a hard drive won't mount on computer A after being connected to computer B, consider booting computer A using the OS on the installation disk from computer B.

    If you need to repair a hard drive with OS X installed on it, you must use that same version of OS X to perform the repair. Using another--in this case, newer--OS can cause quite a bit of trouble, as the directories/permissions may be dealt with differently between the OS's.
    Seems you've learned this lesson--and luckily you didn't lose anything!

  • 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.

  • 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 hard-drive won't mount or be recognized by Macbook

    I just installed a new internal hard drive into my macbook as my old one was failing. Before doing this I backed up all of my information through Time Machine onto a Seagate FreeAgent external hard drive. I've been using this external hard drive for the past two years and I've never had any problems with my macbook mounting it. Once I had all of my personal information backed up I took out the external hard drive and then proceeded to take out my old internal hard drive and installed the new one. I installed the Mac operating system and the Macbook started up just fine but when it came time to reload all of my personal setting using Time Machine my macbook didn't recognize that there was an external drive plugged in. I know it isn't the external drive as it mounts just fine on other laptops. Any suggestions on how I can get my macbook to mount the drive so that I can transfer all of my information onto this new internal drive?
    Thank you!

    Hi...
    Open the Finder. From the Finder menu bar top of your screen click Finder > Preferences then select the General tab.

  • 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!

    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 Firewire hard drive won't mount after 10.4.10 update

    I see many posts about USB drives not mounting after 10.4.10 update. Just lending my voice to that issue (my USB drive won't work either) as well as the 10.4.10 update breaking Firewire drives.
    Hope a fix is coming. No backups are scaaaary.

    How to fix the problem of a missing external Hard Drive (Firewire) after it vanishes from you desktop after installing 10.4.10 update.
    I have a iMac PPC (Non intel). Aparently my system upated installed the wrong version of 10.4.10 and thus my external firewire hard drives a 320 GB Westerndigital My Book, and Acomdata 80 GB, and aWestern Digital 160 GB media center all vanished from the desktop.
    The instructions below should be credited to several different people. I found various version of these steps in the Discussion. I combines a few of them into this one 10 step fix and it worked for me. I hope it works for you.
    1) Shut down you computer
    2) Unplug all peripherals (i.e USB and Firewire, I left computer power plug in as well as ethernet and Keyboard+ Mouse) and leave along for 30 Minutes
    3) Restart holding down the Command (Apple) + Option + P + R keys for three startup bongs, then release the keys and your computer will start up as usual.
    4) Verify and repair disk Permission using Disk Utility. (Several things were repaired here)
    5) Instal 10.4.10 Combo PPC
    6) Restart Again
    7) Again repair Disk permissions (None of mine needed to be repaired fyi this time)
    8) Unplug Power cable and Firewire cable from External Hard Drive (leave along for 1 minute)
    9) Reconnect power to Firewire External Drive first then the Firewire cable to the drive second, then the firewire cable from the Drive to the computer last.
    10) Turn on your Firewire Drive... you will head it spin up and eventually show up on your desktop just like it did before the 10.4.10 update.

  • External USB drive won't mount after 10.9.5 upgrade

    I have reinstalled the combined 10.9.5 OS upgrade, and verified that the drive works when connected to my other MB Pro (mid-2012 running Yosemite beta 3).  There is no third party software that I'm aware of in use for this drive, as it's only for Time Machine backups.
    Thanks

    Is the drive's icon on the desktop (perhaps behind another icon, which is possible if Finder > View > Cleanup is enabled)?
    If not, is the box Finder > Preferences > General > External Disks checked?
    Is the drive listed in every Finder window's sidebar?
    If not, is the box Finder > Preferences > Sidebar > External Disks checked?
    Are Time Machine backups to the drive happening on schedule?
    If not, does the drive appear in System Preferences > Time Machine > Select Disk?
    Can you open /Volumes/Mac-Mini 2/Backups.backupdb using Finder > Go > Go to Folder...?
    Does the drive appear in Disk Utility? Is it (or can it be) mounted there?
    Have you tried to plug it in to a USB port on the Mini (not a hub) or into a different USB port on the Mini?
    Have you tried this: shut down; unplug the drive; boot the Mac; after you have logged in and the Finder is done populating the desktop and menu bar, plug the drive in?
