Can't format internal disk

Hi
I have a Mac Mini from late 2012
I have installed a SSD and kept the old disk for data-storage (1 TB).
Both disk was originally formatted to "Mac OS - extended (Journaled)"
I installed the OS X successfully on the SSD - and everything is working fine on that.
BUT I can't access my data disk. I can see the disk - but I'm not allowed to edit or add anything to the disk.
I have tried a lot of stuff:
Taking the disk out of the computer and reformatting it completly with my Macbook Pro... with out any problems can access the disk and edit on it.
BUT as soon as I add it into the Mac Mini and boot up - the OSX sees the disk but won't let me edit/write to the disk.
Gives error -50
I also tried writing to it from terminal as sudo - no luck.
I tried to reformat it in recovery mode ( and tried booting from USB stick)... BUT the system keeps saying that it can't format the data disk because it can't be unmounted...!
MY EXTRA DISK CAN'T BE UNMOUNTED.... ***!? (also tried unmounting from terminal... same errors)
It has no problems deleting the SSD disk....
-I'm using the well-known; OWC Data Doubler to connect my data disk to the secondary position in the Mac Mini
Please help... because I have no idea how to fix this. (Both disk can be wiped as needed - I just want a system with SSD and normal extra disk)...

Thanks for replying.
My SSD is: Corsair SSD Force Series 3, 240GB 2.5"
I didn't know that you could change any firmware on the SSD it self... and Corsairs homepage do note write anything about it.
I tried to switch the two disk around.
Now it only sees the 1TB disk (apple original) and I'm not able to see the SSD (not even in the terminal)
So right now SSD is in the lower...
hmmm... if I had a problem with the cable or controller - would it throw this kind of error?
Next step; I'll try to install the OSX on the 1TB disk - just to see if the SSD will be reconized later.
But still looking for help.

  • My mac can't find the volume" Data" on Time Capsule. Also Ican't find with the disk utility program the hard disk in the Time Capule; so I can't format the disk again. What can I do?

    My Mac can't find the volume " Data" on Time Capsule, Also I can't find with the disk-utility program the hard disk in the Time Capusule.
    So I can't format the disk in the Time Capsule
    Deconnevt and then connecting the power tp the Time Capsule gives also no solution.
    What can I do?

    I listed the commands.. that is how you manually mount the disk.. follow exactly the commands I gave you.
    In finder use top menu, go, connect to server.
    Type in the following.
    AFP://TCname or AFP://TCIpaddress (obviously you replace with the actual name or the actual IP address).
    If that fails..
    try
    SMB://TCname
    Here is the screenshot.
    tardis4 being the name of my TC.
    It should then ask you for your credentials.
    And it should remember them in the keychain and be able to then get TM to connect.

  • Can't format internal hard disk

    I have installed a Seagate 3 TB drive in an internal slot on my Mac Pro (early 2008), and it looks very strange in Disk Utility.
    The other three disks show "Disk Description :" with the model of the disk (Western Digital, etc), and the name of the partition (which is the same as the name of the disk in the Finder).
    However this disk shows "Name : <the name that I originally formatted it as>" and "Type : Logical Volume Group" and the options "Erase" "RAID" and "Restore" are missing from Disk Utility.
    I have 3 Seagate drives, and 2 of them are showing up this way (the other two are external drives), but one "looks normal."
    Any idea what is going on? Should I try to format this disk (maybe with some terminal program?) or just live with the strange settings on it?

    1. "Note the SMART status of the drive in DU's status area". This doesn't appear because the disk is not formatted as GUID. See the image in my original post.
    2. "SMART info will not be reported  on external drives" SMART info is reported on external drives, at least on my computer. It depends on the kind of card, connection, and case that you are using. With an eSata connection and a modern card and case you can get SMART data from an external disk.
    3. "Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button..." I didn't post this image, but there is no such option for a Logical Volume Group.
    Kappy, I know you mean well, but you posted a canned response that did not address my question. I note that you actually participated in a similar discussion about this same problem.
    I probably should have just deleted the post because it has been answered elsewhere. But I thought that it would have been rude to delete your response.
    It turns out (for those who care) that many people attribute this to a bug Apple introduced into Disk Utility way back in system 10.8.5 but it still isn't corrected in 10.9.1. I still haven't figured out whether this is a glitch that I can live with or something I should try to fix. Links from the article above show possible ways to reformat the disk, which you can't do from Disk Utility in 10.9.1.

    But I can load Win7 from bootcamp partition and it works perfectly.
    Please, help me to find out how to erase internal hdd.

    Are you trying to repartition the drive? Remove the Boot Camp partition only using Boot Camp Assistant.
    If you are trying ERASE the OS X volume/partition and reinstall Mountain Lion from scratch:
    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Satellite U400-112: can't format local disk (damaged MFT?)

    Hello!
    I got rather serious problem with my HDD.
    HDD 250Gb
    C: 116Gb - NTFS - Windows XP (Vista initially)
    D: 1,5Gb - NTFS - (Vista Recover?..)
    E: 117Gb - RAW (was NTFS before crash)
    MFT of local drive E: was damage because of the virus attack (I hope not because of my foolishness!). It was NTFS, now it is RAW. I recovered all necessary data from lost partition with program ZAR, but all my attempts to recover or just format E: remained unsuccessful.
    No bad sectors found on HDD. Windows standard tool for formatting disks fails: "It is impossible to finish formatting of E:".
    Before this problem with drive E:, I got several difficulties with HDD. I have never re-divided disks, as from the very beginning Partition Magic identified it incorrectly. I tried Partition Magic 7 and 8.
    Link: [ Error screensaver|http://cs1498.vkontakte.ru/u169802/154397/x_3a82b4fb.jpg]
    The problem is that special programs (I tried "Find and Mount") also could not identify partitions to correct defected MFT. I thought that low level format may help me, but i heard, what use of any applications from other producers can probably destroy my HDD. Are there any special applications from Toshiba developed for such cases? Or you may advice me something else?
    Thanks for your help!
    P.S. These applications didn't helped me:
    Find and Mount (doesn't find HDD)
    Acronis Recovery Expert (doesn't find HDD)
    OnTrack EasyRecovery Professional (didn't fix error, but helped with data recovering)
    HDD Regenerator

    So have you recovered all your important data?
    I would just run Recovery to restore the HDD back to its factory state. If Recovery fails, you can try removing the partitions using FDISK from an MSDOS boot disk. Free bootdisks can be found at www.bootdisk.com
    FDISK can also repair a Master Boot Record by running this command: FDISK /MBR
    But its not 100% reliable, it could cause more harm than good.

  • Can'f format hard disks with a PM8M3-V board

    Hello,
    Recentl i tried formatting my old pc (P4, PM8M3-V board).
    When i enter my windows disk to the cd-rom, it won't recognize any of my two hard disks, Though almost anything else will recognize them (like partition magic, and other PC's). I can format the HD on another pc, and i have. After formatted, i installed the HD back at thePM8M3-V computer. The computer boots up, and reaches the windows logo screen, and then it restarts and starts this whole proccess again. Also, as it seems, a RAID is configured, since a raid screen is appearing after the initial POST scree, but i could not set it off. I searched for a bit and found out that this:
    Quote
    Integrated Peripherals -> IDE Devices -> SATA Rom Select = [IDE][RAID]
    But the SATA Rom Select line does not appear!
     Please, help me find the problem. Thanks in advanced...

    If you want to reset everything including RAID, you can clear CMOS when the system is powered off by removing the board's battery for 10 secs and placing it back. Once done, power up the system and BIOS is reset.

  • Disk Utility can't mount internal disk but tells me use First Aid?

    I have a Western Digital internal 500 GB hard drive that has failed. At first, Disk Utility did tell me it was damaged but still was able to mount it - giving me partial use. I also ran Disk Warrior and was able to salvage some files.
    My good news is that Western Digital is replacing it, no problem. However, I have to send this one back and I want to erase the contents. But now Disk Utility cannot mount it at all and give me this cryptic message: "The Disk, WD500, could not be mounted. Try running First Aid on the disk and then retry mounting."
    My question is, how can I run First Aid when Disk Utility cannot mount it. (I tried booting from my Install disk and running it from there.) S.M.A.R.T status says, failing. All the usual options such as erase, partition, repair are not available, though the drive shows up, in bright red.
    Any suggestions? Thanks.
    Anyone know of a way for me to simply erase this drive before having to return it to WD.

    Hello Noodle-head;
    Disk Utility cannot mount it at all and give me this cryptic message: ...
    So you're having a HD mounting problem, Hmm.
    I have tried selecting both. Neither gives me any options.
    If the HD shows up in the Disk Utility App then there's a way to toast it.
    Whoa! ... Now if I can just find out what a magnetron magnet is...
    Don't bother because the only magnets powerful enough to scrub data from a drive platter are laboratory degaussers or those used by government agencies to wipe bits off media. That's the reason why the Disk Utility App has a '35 Zero-Pass Security Erase' option.
    So you have two choices ...
    Your first choice is to just send it back and don't worry about it. I doubt that WD will try to access your data unless you want them to. It's very expensive to retrieve data on a dead/dying HD. All they will probably do is verify that the HD is dead/dying & send you a replacement.
    Your second choice depends upon your knowledge of Unix, if you have more than one Mac, plus if you have a Windows PC.
    Let me know if you want to 'toast it' or not.
    Later ...

  • [SOLVED] usb install of arch can't find internal hard disks

    I installed arch to a 4gb usb flash drive and it works great.  Keeping it bare bones for now without a GUI to force myself to learn more about linux and how it works.  However, I would like to mount and access the internal hard drives of the "host" computer that i'm booting the usb on, and I can't seem to find them.
    ls /dev/disk/by-anything only shows the usb device that arch is installed to and udev and something else I can't remember right now.  Same results when I enter df -h.
    I know that this is possible somehow, because I also have a live usb of Ubuntu 10.10 on another usb stick that can access the internal disks.  However, my ubuntu stick also has a gui, Hal, etc and is a persistent live-disk-to-usb rather than an actual usb stick installation.  Does that affect things?
    I apologize if this is already covered somewhere.  I am a super n00b with arch and I did my best to search both google and the forums.
    Thank you in advance, and I look forward to being a part of the arch community!

    i've looked through the kernel log, and realize that i've never looked at one before and don't really know what i'm looking for.  if i haven't lost your interest yet, here's a pastebin of a recent boot... the PNY is the usb stick that arch is installed to.  http://pastebin.com/D7nzkaaq

    i will do this next.  i'm pretty sure that the cables are connected properly, seeing that i can boot the computers in question without the usb stick and have full access to available drives.
    thank you everyone for all your responses so far!
    EDIT:  alright, i looked at /proc/partitions and this is what it says:
    major minor  #blocks  name
       8        0    3915776 sda
       8        1    3915744 sda1

       3        5     473886 hda5
       3        6   33350877 hda6
    so it looks like my internal drive is recognized somehow.  my new question would be, what exactly is the difference between /proc/partitions and /dev/disk/ ??  and how do i find out more identifying/location information about hda to mount it into an accessible location in my file system?

    After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it. See below for how to clone a drive.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

  • Can't unmount an internal disk that I installed in my tower

    Years ago, I added a supplemental internal hard drive (Maxtor) to increase my storage capacity. It continues to work fine. But...
    I'd like to be able to do maintenance on it (verify the directory, make any repairs, etc.), and for that, I need to be able to unmount this disk.
    Note: there is no eject icon next to the disk's name in my Finder window.
    I always get the error message that the volume could not be unmounted, and I've tried to unmount it several ways:
    - Used Terminal to try to unmount
    - Used Disk Utility to try to verify &/or repair
    - Started up with a bootable clone and tried
    - Started up with a bootable Disk Warrior CD and tried
    - Tried to reformat/erase the disk (couldn't)
    I have backed up to this drive, using "erase & copy files" (from a sparse image backup), and that worked, so apparently it didn't need to unmount the disk to do that. But I can't copy my computer over to my laptop (in Target Disk Mode), apparently due to this problem. Sigh.
    Disk Utility tells me to be sure all folders, files, etc. are not in use on this disk, and then maybe it will unmount. But I see nothing in use or open.
    NOTE: I have Sys 9 installed on that volume. For a while, I thought maybe OS X somehow keeps a file open that's related to OS 9 (like maybe sort of having it "stand by" in case Classic needs to load when I try to open an old file or something). But that doesn't seem to be the case after all, since I've booted from a bootable clone on a different, external drive (meaning my normal boot drive is not loaded), and the problem persists. But wait, maybe the clone I've booted from is somehow activating the OS 9 disk in that way, still. But wait, that can't be it, since I've booted from Disk Warrior CD and the problem persists.
    Shouldn't I be able to do maintenance on that additionally installed internal disk? And doesn't it have to unmount for that? But how can I get it to unmount? If there is a directory problem causing this, how can I repair the directory to resolve the unmounting problem, if it won't unmunt to accept the repairs? And why isn't there a way to just erase the disk and start over? I guess it has to be unmounted first, fir ANYthing. But HOW??
    Many thanks.

    Hi, Larry.
    You wrote: "I always get the error message that the volume could not be unmounted"This implies that you have either:
    a. A file open that is saved on that disk.
    b. An application or background process running that was either launched from that disk or is using a file on that disk.
    c. A Startup Item or Login Item is either being launched from that disk or using a file on that disk, akin to points (a) and (b). See my "Troubleshooting Startup and Login Items" FAQ.
    Try restarting in Safe Mode and after logging in, launch Disk Utility.
    Good luck!

  • Moving iPhoto to external drive; have formatted external disk to Mac OS Extended (Journaled), moved the iPhoto library to external drive; when trying to change the library, the iPhoto file on new external is greyed out   can't be selected.What went wrong?

    Must have done something wrong..
    1.  formatted external disk to Mac OS Extended (Journaled) - required a partition, but that went fine.  Entire new external disk was included in the partition formatted to Mac OS Extneded (journaled).
    2.  moved iPhoto library to new external disk
    3.  Holding Option key down, opened iPhoto
    4.  Choose library feature appeared, however when new library function option appeared and "choose library" selected, the iPhoto folder appearing in the new external drive was greyed out and not able to be selected.  Therefore the default library remains the original iphoto library on the Mac. 
    I've moved the original iphoto library to the trash and then tried to start iPhoto.  A message comes up that the iPhoto is in the trash and needs to be pulled out before iPhoto can start (clearly the new iphoto library on the external drive is not being seen.
    Can anyone suggest where I went awry?  Thanks!

    Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
    (On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
    (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
    What's the plist file?
    For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
    Then try select it again.

  • I would like to make one static copy of Firefox, so I can restore it if I have a hard drive crash, or if I want to upgrade my internal disk, or if I want to have a duplicate on another replacement computer.

    I would like to make one static copy of Firefox, so I can restore it if I have a hard drive crash, or if I want to upgrade my internal disk, or if I want to have a duplicate on another replacement computer.

    Hi tchmielewski,
    You should look into [https://support.mozilla.org/en-US/kb/what-firefox-sync Firefox Sync]. I think it will do everything that you are asking for. This will allow you to have all of your Firefox preferences and settings shared across multiple computers.
    You could also create a backup on a USB drive in case of catastrophic failture. I would suggest that you back up your personal information and bookmarks using the article [[Backing up your information]].
    Hopefully this helps!

  • After upgrading to osx 10.9.3, my external hard drive was not able to mount, but it can be mounted without issue in osx 10.6, how do I solve it? it was formatted by disk utility.

    Thanks
    PT

    From the menu bar, select
     ▹ System Preferences ▹ Energy Saver ▹ Power Adapter  
    and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
    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.
    Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
    Start up in Safe Mode and test.
    Reset the NVRAM.
    Reset the System Management Controller.
    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.
