Internal hard drive fails to mount in Disk Utility.

My internal hard drive fails to mount in Disk Utility for the past year, so I cannot verify it. However, it does mount in Disk Warrior. (1) I am concerned that it will not mount within the Apple software, and what that bodes for my computer. (2) I also have MANY spinning beach balls daily and have to use the power button to reboot. I just bought extra Crucial RAM and have yet to install it. Somehow, I don't think it wil help my issue # 1 though. Please advise, anyone out there! Thank you.

No, there are never any errors like that. Also, I have upgraded the Mac OS from 10.5 to 10.6.8. That did nothing. I backed up my Users = Christina folders to a good, 15 year old Firewire 800 La Cie 1 TB  external hard drive. I also tested using the Apple Hardware test, which showed no problems, and Alsoft's Disk Warrior and defragged, and fixed a very minor issure re directory count, probably resulting from many improper shutdowns lately due to frozen spinning beach balls. None of these procedures alleviated the issues, and I still have the same issues: mainly that super-frequent spinning beach ball. Do you think I ought to install that new RAM sitting here finally? Perhaps it is a lack of RAM??I only have 2 lousy GB's of RAM after all! Thank you so very much for a reply.

  • Internal hard drive does not mount in disk utility

    My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each:  Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

    The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
    How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
    When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
    If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
    I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
    If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
    Then consider a later version OS X -- whatever most recent version that model can support... {edited}
    Good luck & happy computing!

  • Internal hard drives won't appear in Disk Util

    I have a bizarre problem with my hard drives now. I'm on a 2.4GHz Core2Duo Macbook Pro 15" with 10.5.4. I've switched the hard drive a couple of times before with no issues whatsoever. Now, with the exception of the brand new one that won't hold an install, my internal hard drives don't show up in the install disk's Disk Utility.
    I got a new hard drive to try the other day, installed it, booted to my OSX install disk to use Disk Utility. I switched the new disk to GUID and formatted it as journaled like usual. It took 4 hours to do the install, then after the restart it tanked. It booted back to the install disk where I checked it out. It could not repair the file system, and the drive was not "mounted". I mounted it, repartitioned and formatted it, and installed again. This time it stopped halfway through the installation and said the drive might be corrupt.
    I unplugged the cable and battery, held the power button for over 5 secs, then just let it sit for about 10minutes with no power source while I thought about this. I put the original drive back in, booted into OSX, and put the new hard drive in an external USB enclosure. I formatted it while in OSX, then rebooted into the install disk and installed OSX on it while it was in the USB case. It took the installation more quickly (about an hour and a half...still not 20min like my old 7200rpm Hitachi 200g), then I booted into its OSX while in the USB drive. It booted ok, so I downloaded the updates and clicked to install them. It then went into a revolving restart. Eventually I decided it was not doing this because it was happy so I shut it off.
    I swapped the hard drive out with another new one, and this one would not complete an installation while inside the computer either. It acted similarly while in the USB case. HOWEVER it would always show up as unmounted after a restart and would not recognize the drive inside the computer as a bootable disk.
    I put my original drive in there to give up, and it gave me the ? folder. I booted to the install disk and it did not show up in the disk utility. I put my old hard drive in the USB case, booted to the install disk, and it showed that it was there, but unmounted and it could not repair the file system.
    I repartitioned my hard drive (i have time machine working..not a huge setback) in the USB case and put it back in the computer. It still would not show up in disk utility. I put it back in the USB case, installed OSX onto it (in about 20min), restarted a couple times, saw that it was working, put it into my computer, and got the ? folder again.
    I went out and bought a stardard 160GB SATA 5400rpm Seagate drive to try in there, and this fresh drive is not recognized inside the computer either when I boot into disk utility.
    The brand new hard drive WILL show up in Disk Utility when I boot to it from the install disk, but it will not survive a complete installation.
    So now I'm running OSX from my original hard drive in a USB case until I can figure out why the old disk recognized inside my laptop is the new hard drive upgrade, but it cannot complete an installation on it.
    I'm originally a Windows slave, so I can only think in terms of AHCI or SATA-card drivers, or screwed up bios. But this is all pre-os-boot, and the apple firmware seems to be pretty automatic in picking the right settings to see stuff.

    I kind of feel like drawing a flowchart to show all that I've tried. Its difficult to keep everything intelligible while listing the entire last week's efforts at 2:45am. :-/

    I also explained it here, perhaps a bit differently. Maybe some reply there might spark someone's memory of a possible problem. I understand the nature of computers (been 100% geek for 20 years), but I'm hoping there's someone out there with the specific Apple expertise to help me out. Eventually the processes I've taken and my specific situation will become clearer as the questions widdle away at this.
    My original 7200rpm SATA drive that works fine won't show up when connected to the SATA cable. I've repartitioned it with HFS, and repartitioned it as free space in the USB enclosure. It simply won't show up in Disk Util. Same with the brand new test SATA drive.
    The new SSD SATAII does show up, but after a 4hr install the partition is unmounted and won't show up as a boot option. I can boot to the install disk and repartition it, reinstall, or remount it. But it will never be mounted to be booted from while connected to the computer. I've had 2 of the SSD's to try, one survived one restart, then went into a never-ending restart cycle after I installed the updates. The 2nd has never successfully been mounted after the install to boot from. Now nothing can be mounted to boot from within the computer. I have to boot off of any of these drives from the USB enclosure.
    If I install OSX on them while in the USB enclosure, that works, but they will not mount when connected to the SATA cable inside the lappy. The platter style SATA drives won't even be recognized...
    Thanks for the instant reply, this is driving me nuts 'cuz it makes almost no sense. Thanks so much to everyone that contributes. I appreciate everything.

  • My internal hard drives don't appear in disk utility. Can't install os X

    Hi,
    I have a macpro. In this computer are 4 1TB hard drives. They were set up as a raid set. I booted my comp with a snow leopard install disk and opened raid utility to delete the raid set so I can install os X on one hard drive and use the other hard drives to store files. After deleting the raid set, I opened disk utility to find no disks in which I can reformat or even install snow leopard. What steps do I take now to ensure all disks are useable and that I can install my operating system on one of them?

    Drive Preparation
    1. Boot from your OS X Installer Disc. 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.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    Now if you wish you can repeat Steps 2 and 3 on the other three drives. Or you can do it after installing OS X.
    Once you have one drive reformatted you can quit DU and install OS X.

  • I'm an avid Mac enthusiast who works in a creative field. However, I simply cannot afford a new Mac after my old one's internal hard drive failed. Can anyone recommend an affordable Mac option? I don't want to consider a non-Apple product.

    Macs with a FireWire port will also boot happily from an External drive. You don't even need to open the MacBook.
    Some users buy a drive they would like to have as a future Internal drive, and also buy an external enclosure. They get the External set up the way they want it, then swap with the Internal drive.

  • I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out.

    I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out. I am trying to determine what is wrong with the drive.
    I need the data on the drive and it won't show up in Disk Warrior. I have tried different Mac's and different USB cords only to find the same outcome. When selected in Disk Utility the information read as such...
    Disk Description : WD Elements 1023 Media                      Total Capacity : 500.11 GB (500,105,740,288 Bytes)
    Connection Bus : USB                                                               Write Status : Read/Write
    Connection Type : External                                                     S.M.A.R.T. Status : Not Supported
    USB Serial Number : 575837314135304D36373132        Partition Map Scheme : Unformatted
    As the drive shows in Disk Utility there must be some life left in it surely. There is a possibilty that the physical connection between the USB cord and the external drive is damaged but since the drive shows up I believe it's unlikely... before I give it to the pro's is there anything else I can do to diagnose the issue?

    Hello,
    I have just experienced the same thing!
    Although my external drive shows in Disk Utility, it does not show in Finder.
    And the Verify/Repair buttons are also greyed out.
    Also, although the drive is 2TB. DU shows it as having Total Capacity of only 4.14GB! (Which should be the Free Space).
    I was wondering if you solved your problem, & if so, would you share your solution.
    I´m afraid to Erase in case I lose all my Data on the drive.
    Thanks in advance for your reply!

  • Both Internal hard drives fail on Macbook Pro late-2011

    Both internal hard drives (SSD and HDD) failed on Macbook Pro late-2011.
    Setup: MBP closed with Thunderbolt display attached.
    Problem on HDD-A
    I called Apple Support to log an issue with my MBP2011. The system is made up of 2 drives - SSD (128GB) and HDD with 2 partitions HDD-A and HDD-B(original 750GB).
    HDD-A has LionOSX 10.7 and HDD-B is storage. SSD has LionOSX on it as well. I normally boot HDD-A.
    I was working on HDD-A and the Kernel Panic screen appeared prompting me to shutdown the machine and start it up again.
    I tried to reboot HDD-A and the grey progress bar appeared for a long time. I then forced shutdown and rebooted into SSD.
    I was able to boot from SSD and then I opened Disk Utility to check the drives. I verified the disk for HDD-A and there was an error. I then tried to repair disk and it couldn't repair it. A dialogue said the disk could not be repaired and that data should be backed up.
    HDD-A was not visible in Finder but HDD-B was accessible.
    I verified HDD-B and it was "ok".
    I shutdown, booted from SSD, disk utility HDD-A and the same message occurred.
    I called Apple Support and they advised that I boot from my external HDD which was a clone of HDD-A.
    Solution
    I was successfully able to boot from the Clone HDD-A.
    HDD-A was able to be accessed and I could retrieve the files from HDD-A.
    I copied over the latest files from HDD-A to an external drive.
    Same Problem on SSD
    Boot from SSD, i started working for about 3 hours, with the lid closed, and attached to the ACD.
    Kernel Panic screen happened again on the SSD.
    Couldn't boot boot from either SSD or HDD-A.
    I booted from Cloned HDD-A, Disk Utility verify and repair returned errors on SSD. The same issue had occurred on the second drive.
    Disk Recovery from a boot recovery USB thumb, Disk Utility, erased SSD, verify was ok.
    Tried to install then there was an install error saying that SSD was damaged (large triangle warning icon). Tried 3 times, failed.
    Boot from Recovery Drive HDD-A, downloaded LionOSX.
    Next steps
    Format HDD-A and HDD-B into 2 partitions
    Install LionOSX on HDD A.
    Note:
    I did not do any software updates for about a week before 14.04.2012 and suspect it might be due to the virus.
    I normally work with the lid closed and attached to the ACD, I also suspect that overheating caused both drives to fail. However, I have been using this system with the lid closed for atleast a week. One Kernel Panic screen occured.

    Depending on what you are doing on the computer, how hard you are working the computer, it should not overheat. And if it does it should shut down or get very slow because when it starts to overheat the CPU will be throttled back to a lower Ghz speed and or just shut down so it doesn't cause damage to the CPU. The Kernel Panics are a sign that something else is going on. This could be software or hardware.
    If after wiping the drives and reinstall Lion on the SSD if the system is running OK then the drives are fine, IE they are not bad. There is something else corrupting them. Again this could be hardware or software, but I doubt it is heat. And using the MBP ion clamshell mode should not cause overheating or excessive heating of either of the drives.
    Have you installed iStat Pro or Menu and kept and eye on the temps? If not install iStat Pro and keep and eye on the temps. I bet they do not get above the 150°- 180°F mark which although hot is not overheating.
    Be very careful when calling Apple. Removing the DVD drive and installing a hard drive in that bay could void your warranty. The DVD is not a User Removable part and Apple frowns on doing that. So if you call them do not mention that you have replaced the DVD drive with another HDD.
    Honestly I suspect you have a hardware problem. But the only way to know that is to install just Lion and your basic programs and run the system. Leave out any AV type software, if you are running some. If you don't get any kernel panics thenn install some of your other software, one programm at a time. If with just the OS and basic software you get a kernel panic then it is hardware related and needs to be checked out by Apple. If you do that re-install the DVD and the original HDD with just the OS on it before you take it in.

  • My iMac ( Summer 2010 ) internal Hard Drive failing.. It's a Seagate 500GB HDD.

    My new iMac  ( summer 2010 - July 2010 ) internal Hard Drive is failing..
    1)  sometimes the imac can't see the hard drive to boot from..
          it would stay in the grey screen ..
    2)  sometimes the imac boots up after a cold start.
         but some applications such as Safari would die or crash on me.
          I think the file system on the mac is corrupted.
    I believe that the internal hard drive is failing..
    I can boot up from the external firewire 800 hard drives fine..
    The internal hard drive:
    Model:   ST3500418AS
    Seagate Barracuda 7200.12 SATA 3Gb/s 500GB Hard Drive

    Why not starting from the external HDD, and then do a "Repair Disk" of the Seagate.
    If that does not help buy a new HDD, put it in and clone the latest external disk to it :
    When you have two external disks, make a clone of the Seagate on the one that does not have the latest backup, because the Seagate may fail while doing the cloning. Use Carbon Copy Cloner or Superduper.

  • Internal hard drive for use as scratch disk

    Am running OS 10.4.11 on a dual core 2.3 Ghz PowerPC G5. Want to install a 2nd internal hard drive for use as a scratch disk w/ FCP and for my media files, etc. Given that I can only accomodate an SATA I drive w/ 150 Gbps transfer rate what might some decent choices be for a 500 Gb to 1 TB drive suited for video (and a PowerPC G5)? I'll also be adding an external drive for backup if anyone has any suggestions.

    Thanks for the recommendations. I had been looking at the Hitachi CinemaStar series but you have to reset the drive to SATA 1 for use w/ a G5 PowerMac. Resetting the drive, according to Hitachi, can only be done on a PC which I don't have access to. And I think that holds true for all their drives that are not strictly SATA 1.

  • G5 tower now boots, but one of the internal hard drives won't mount!

    For those of you who saw my previous thread, my G5 tower would turn on and play the startup chime, then sit there until the fans ramped up. It seems that the problem was the Belkin PCI card. I removed it, and the machine started up with no problems.
    Now, however, one of my internal hard drives (not the primary one) won't mount. Various programs can't even tell it's there. I'm completely lost as to how to solve this problem. My first thought was to try to swap it into an external case to see if it would mount that way. Thoughts?

    One, possible two posts should read ground. Test for continuity against the metal case. Another should read 5V+DC. I think the four prong are: ground, ground, illumination then power. The connectors are gold plated and should not corrode, however, they are no match against fine particles of dust. You can carefully unplug both sides of the drive connections and vacuum. Usually, to unplug and re-plug is enough to get it to work again. When there no power coming off the logic board, you can find a Y-splitter and power off the other drive.

  • Internal hard drive failed - install Mac OS X on external firewire?

    Hi, hope someone can help me.
    The other day my internal hard drive in my MacBook started to click. I did a hardware test, and the drive now doesn't show up at all, either in the test or when I go to install Mac OS X.
    Is it possible to buy an external Firewire hard drive, and install Mac OS X on it, even though the internal hard drive isn't recognised?
    Here is the external hard drive I was going to buy http://www.amazon.co.uk/Western-Digital-Premium-External-Firewire/dp/B000F6SGB4/ ref=sr11/203-7120413-7742330?ie=UTF8&s=electronics&qid=1174334464&sr=1-1
    Also, is there any thing else I need to know before I do this...
    I need to boot from an external hard drive as I cannot go to an Apple store to get it fixed and I am not really in a position to send it off for repair, as I am at Uni.
    Thanks for your help!

    You need to call AppleCare Support and get the hard drive replaced. None of the MacBooks are a year old yet, so they're all still covered by the original one year warranty. This sounds like a problem that should be covered, why bother with an external drive? If you're not willing to be without it, yes, you can install Mac OS X to a FireWire or USB 2.0 hard drive and run your MacBook from that.
    -Doug
    P.S. If I were you, I'd spend the extra £15 and get the 320GB version of that drive. I'd get as big of a drive as you can!

  • Windows based WD external hard drive not showing up in Disk Utility to reformat to Mac... how can I erase the drive

    We have a WD external harddrive previously used with a PC that we want to completely erase and reformat for use with our iMac desktop for use with Time Machine.  The drive shows up on the desktop of the Mac, but it does not show up in Disk Utlity, assuming because it's Windows format.  Outside of the standard "erase" feature in Disk Utility, is there any way to reformat this drive for Mac OS X?  Or how can I get this drive to show up in Disk Utility?  Note: The drive functions properly, has power, and we are able to view its current contents through the desktop icon, so it is a working drive.  And we are ok with losing all the current data on the drive.

    Hmm strange, I had just moved my external Lacie drive from my windows machine to my iMac and it was showing up in disk utility still formatted fat32 or whatever. I would disconnect the drive and restart the machine then replug the drive and try again.
    Also not that it will make a difference ( I dont think it will but hey why not ) try accessing disk utility from the install disk?
