Mac OSX wont reognise my internal hard disk drive

I have a problem where for some reason when I start up my Macbook Pro (intel core duo) it does not detect the internal hard disk drive at all. I have run a hardware test and it shows no problems whatsoever. I have tried resetting the PRAM etc and to no avail. Yesterday the system hung and I tried to force quit and it wouldn't do anything so eventually I held down the power key and when it tried to reboot this is the problem I was faced with (it would boot up with the "no entry" sign). I accepted complete defeat and went to completely re-install OSX however it doesn't even show the internal hard drive when I wait for it to give me install destinations. I had tried seeing the hard drive through disk utility however it only shows the install DVD and that's it in the sidebar. I resigned myself further to thinking either the logic board or the HDD had packed in all and I took it round to my brother in law to see if there is anything he could do without opening the machine (he is Oxford educated and writes programmes etc so is very knowledgable), now this is the part that has miffed us both, he started it up using a Linux disc and once running, Linux see's the hard drive with no problems. He has been able to access the HDD with absolutely no problems under Linux both reading and writing to it. I even took my Mac Mini round and he booted them both up in Linux and completely copied Mac OSX from the mini to the macbook pro but still when I try booting up its as if the HDD isn't even there. Why can Linux see the drive and not Mac OSX? Please don't be affraid to get very technical in your answers as they may mean nothing to me but will probably all make sense to my brother in Law. Any sugestions at all would be greatly accepted.

Dear mcdkev,
You guys may have made a big error cloning the Mini HD into the MBP. They both have very different drivers and hardware settings and their OS X versions are customized to fit the hardware. That is why each mac comes with it's own version of OS X and their backup disks. That's a reason why it did not work.
Ok, so now that you do not have any of the original info on the MBP try the following:
Use linux to scan the disk surface & repair any problems.
Reformat the drive as DOS or FAT 32. (I wouldn't go into any linux specific format unless you can "Apple" format it, which I don't think linux has that option.)
Now, the MBP should be able to see it's drive...
boot from the OS X DVD , from the Utilities menu choose Disk Utilities, partition the drive as GUI file system (in case the linux format made the drive a "system boot record", you do not want that... )
Then format the drive as "OS X Extended Journaled"
Now go back to install and install your original basic set of OS X (the factory default).
*If nothing works, please do take your MBP to the Apple store or to a certified tech before you do more damage to the drive and it becomes unusable ...*

  • Is it possible to upgrade the internal Hard disk drive on the iMac

    Is it possible to upgrade the internal Hard disk drive on the iMac?

    Yes but it's definitely not advised. If you have a machine newer than 2009 Apple uses drives that have integrated heat sensors. This makes upgrading much more difficult but not impossible. If you have a machine still under warranty then definitely DO NOT do this yourself as you may void the warranty not to mention it isn't for the faint of heart. Take the machine to an AASP to have the work done, you will need to find one in your area willing to do so.
    If you are considering a new machine then simply buy the configuation you need.

  • Powerbook won't see the internal hard disk drive

    I'm scratching my head with this one...
    Seemed to me that my HDD had died, when I booted the computer I got a grey screen. I tried using Firewire Target Disk but the other computer connected didn't see any drive pop up, and when I booted from the installer CD the HDD did not show up in Disk Utility.
    So I bought a new HDD and replaced it, but the problem was the same. I took what I thought was my dead HDD and put it in a 12" PB and it booted fine (and I was able to get my data off it that I'd thought I'd lost).
    The problem I now have is that I don't know the reason why the HDD is not working. I ran the Apple Hardware test and the PB passed in both the basic and extended tests. The software reported that the mass storage (I presume that is the HDD) passed. I don't understand how it can pass when the HDD doesn't show up at all.
    I'm hoping the problem might be the HDD ribbon connecting cable as that would be a 10 quid replacement, but with no feedback from the hardware test I haven't a clue.
    Has anyone else encountered something like this and can they give me suggestions?

    Looks like your HD cable is the problem.
    Apple hardware test will not tell you that the problem is your HD ribbon cable. But from my past experience with this kind of problem, I could tell you that most likely your problem located in the HD ribbon cable.
    You've tried your HD in another unit and it is working fine and by process of elimination then the HD cable is next to be tried and if after you replaced hd cable the problem still persist then you can tell that the culprit is the logic board.

  • How does one SUCCESSFULLY transfer Time-Machine backup to a new (larger) hard disk drive using OSX 10.5.8

    I have read a number of articles about how to transfer a complete Time-Machine backup to a new (larger) hard disk-drive.  Some of these articles are specifically for OSX10.6 users, which are not applicable to me since I am operating with OSX 10.5.8.
    However, I have tried several times to use the Disk Utility 'Restore' function, dragging my old time-machine volume into the 'Source:' box and my new volume into the 'Destination:' box.  This works, of sorts, BUT the newly created volume on the new larger hard disk-drive remains the same size as the original volume on the old Time-Machine HDD, with no apparent way of increasing the new volume's size.  So I am not really any better off:
    E.g. the total capacity of my new HDD is stated by 'Disk Utility' to be 465.8 GB, of which I'm told 228.2 GB is used for the Backups.backdb folder, but only 4.6 GB of free space is actually available.  Yet under the 'Partition' tab of 'Disk Utility' it tells me that there is still 236.4 GB of available space.
    Does anyone know how to resolve this issue without upgrading to OSX 10.6?

    First, how did you prepare your new drive?  See:
    Drive Preparation
    1.  Open Disk Utility in your Utilities folder.  If you need to reformat your startup volume, then you must 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.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    If you plan to partition this new drive then be sure you create a larger partition for TM than your old volume.
    Next, clone your old TM volume:
    Clone using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4.Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.

  • Problem installating Snow Leopard on old Macbook Pro with Intel Core 2 Duo. After creating partition on internal hard disk (Extended Journaled), installation starts but stops at half of the progress bar. Screen asking Restart appears.

    Hello:
    I have tried installing Snow Leopard via the installation disc on a Macbook Pro (2007) with an Intel Core 2 Duo, but I the installation has failed more than 5 times.
    I have first formatted and partitioned the internal hard disk with Mac Os Extended Journal format.
    Once the installation starts, it starts without a problem unti lthe progress bar gest until half completed then a screen asking for a Computer Restart shows up.
    It asks to press the power button for some time until it the computer shuts down and then, press again to turn it on.
    Once turned on, the installation disc gets readed, the installation screen appears again and asks again to start the whole installation process form the beginning.

    Then you have a Hardware Problem.
    Your system is Crashing part way through the install and Re-Booting because of the crash.
    Could be the drive itself or it could be some other hardware part in your system. Like the RAM.
    To check if it is the internal drive connect an External drive to the system by USB and do the install on that external. If the install completes then it more then likely the drive is bad. If it crashes again then it is more then likely some other piece of hardware in your system.

  • No way to free space in the internal hard disk.

    Hi guy
    There's no way to free any space in the internal hard disk. If I throw 5 giga of files in the trash and empty it, I don't find 5 more giga of avalaible space in the internal hard disk. Time Machine is not activated. Any idea to solve the problem? Sorry for my english....

    Freeing Up Space on The Hard Drive
      1. See Lion/Mountain Lion/Mavericks' Storage Display.
      2. You can remove data from your Home folder except for the /Home/Library/ folder.
      3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
      4. Also see Freeing space on your Mac OS X startup disk.
      5. See Where did my Disk Space go?.
      6. See The Storage Display.
    You must Empty the Trash in order to recover the space they occupied on the hard drive.
    You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
    Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

  • Ssd internal hard disk  compatible for a macbook2010

    Hy everyone!i need help to choose  a new hard disk for my Mac book pro 2010!
    I was wondering which ssd 2.5 inch internal  hard disk brand is compatible for it?
    I would go with a crucial or samsung,but i really don't know what i should notice before choosing.

    stefanobernardini,
    I put a Samsung 840 PRO SSD in my Mid 2010 MacBook Pro. It’s been working flawlessly for me so far. Other people here have good things to say about the SSDs made by Crucial and by OWC, but the 840 PRO is the only one which I have experience with, so I’ll restrict my recommendations to it.

  • Internal hard disk really slow to write new files

    Hi
    I've had some problems with my mac lately;
    it was running really slowly so I ran tech tool deluxe and it detected a bad surface sector.
    I wasn't sure how to fix this so I copied everything from my internal hard disk onto 2 external hard disks.
    Then I deleted all documents, files and most apps from the internal hard drive and zeroed out all free space using disk utility. (Which took four days).
    Finally I did a re-install of leopard and ran tech tool deluxe again, which came back with no problems.
    However, now I'm trying to copy all the files back onto hard disk it's taking a very long time e.g. iTunes files totaling 31.41GB would take 14hours
    Trying to move the same iTunes files to the other external hard disk takes 25 minutes.
    Any help would be appreciated

    Then I deleted all documents, files and most apps from the internal hard drive and zeroed out all free space using disk utility. (Which took four days).
    It should not take four days to zero out free space. And it should not take 14 hours to write 30GB of data from a directly connected external drive. There is probably a problem with the part of the drive that was not deleted and zeroed; in the system installation. Or the problem could be in the disk directory structure.
    The only way to fix it is to erase the entire drive. You should not need to zero out data, although doing so would do no harm and should take no longer than a few hours (depends on size of drive). Then reinstall a fresh copy of Mac OS X. After going through the updates and installing your apps, restore your personal data from those external drives.
    If the drive is still acting slow, you may have a hardware problem with the drive.

    When formatting has completed quit DU and return to the installer.  Complete the OS X installation.

  • MacBook does not see internal hard disk

    Sorry if this is already answered somewhere, but I have searched so many forums that my head is swimming!
    My boyfriend connected a new USB drive to his MacBook, formatted the new disk, copied some backup data onto it. At some point, the MacBook hung, so he held down the power key until the MB turned off.
    Each time we restart it now, we get the flashing-folder-with-question-mark, and Tiger won't boot.
    I have tried almost all of the tips I can find, and was even willing to reinstall OS X, however... the MacBook does not appear to see it's internal hard disk. As such, I cannot perform first aid on the disk via booting to setup DVD, and I cannot reinstall OS X.
    If I boot from the OS X install disk, and use Disk Utility, the MB only sees the CD-RW/DVD-RW drive and the install disc. No internal HD ever shows up.
    Help! I am at a loss as to how to fix...

    Let me guess: you're also experiencing a low clicking noise from the right side of your mac immediately after you turn it on, right? Same thing happened to me and others, in fact there are several threads on this subject already:
    http://discussions.apple.com/thread.jspa?threadID=960977&start=0&tstart=0
    http://discussions.apple.com/thread.jspa?messageID=5325539&#5325539
    My drive was done for, and no data could be saved. I ended up buying a new drive, and now I'm just hoping the same thing doesn't happen again. I'm beginning to get a sense that this problem is occurring on a more frequent level now that the 1st generation macbooks have reached their 1-year birthday, give or take. Let's hope Appel fesses up if it is indeed a design flaw.
    Anyway, you most likely need a new drive. I just got a Hitachi Travelstar 250 gb for around 200$US, so they're quite cheap, and VERY easy to install, just 3 screws, slide it in, boot up, run disk utility, erase/format and you're good to go.

  • Disk Utility hangs while initializing internal hard disk in Core Duo iMac

    I have a 20" Core Duo iMac. Recently the internal hard drive crashed ("invalid B-tree node size" or something reported when Disk Utility tries and fails to repair it). I have all my data on an external hard disk used as a Time Machine volume, so recovery is not my issue. Initially I picked the write zeroes once security option and chose to erase the internal hard disk. Realizing this would take too long, I clicked on skip, and Disk Utility appeared to hang. I quit and restarted Disk Utility, and chose the "don't erase" security option, but when I go to erase the drive it appears to hang while at the "partitioning" stage and doesn't seem to get any further. There is motion in the progress bar, but no additional progress after about an hour. Disk Utility shows the disk but no volumes underneath it (whereas immediately after the crash, it showed an unmountable volume labeled "disk0s2").
    Why would Disk Utility be taking so long and not making any progress? How can I reformat this disk if Disk Utility is not able to? Incidentally, I am running the Disk Utility that comes with OS X 10.4.8, since that is the OS X version on my portable hard drive that I booted from. I also tried using Drive Genius to initialize the hard disk, but it also appeared to hang with no progress.

    It is possible the drive has failed, but to be sure start by turning off the computer. Wait five minutes. Then do this:

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. Set the number of partitions from the drop down menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.

  • Add Internal Hard Disk?

    Hello, I have a running Windows 7 installation on my Mac Pro and recently added another internal hard disk. It is formatted in HFS+. However, Windows 7 does not allow me to add a letter to the new hard disk - whereas the third HFS+ hard disk already existing at the time of the BootCamp setup has a letter assigned.
    Does this mean that, for having the new HFS+ disk reckognized correctly, i need to reinstall Windows 7??? Any suggestions would be highly appreciated.
    Many thanks, Stefan

    Hi turbostar, thank you for your response.
    It is a brand-new hard disk freshly formated as mac journaled. My plan was to use it as a data container with de-activated user rights and Paragon HFS+ installed on the Windows 7 side (just because I will mainly use this drive under MacOSX and just sometimes under Windows 7; and hd space on the Windows 7 partition is very scarce).
    So I guess the answer is "both". Paragon HFS+ documentation tells me that I shall assign a drive letter under Windows 7, and this is currently not feasible.
    Again, thank you for listening.

  • Best protective cases for bare internal hard disks used with drive dock?

    I've been noticing that my external, powered hard drive enclosures are taking too much space; plus I think I can save money by plugging internal hard disks into a drive dock such as http://www.newertech.com/products/voyagerq.php , then connecting that via FireWire 800 to my Mac Pro.
    However, I don't want to leave them exposed when not active. I've searched around and found several options like silicone holders and WiebeTech's VHS-esque boxes, but not a really thorough roundup of protective cases.
    Does anyone have any firsthand experience or recommendations for protective cases?

    Thanks for the Google Base link, but it doesn't seem to work any more.
    I did manage to find some cases from a company called Technology Directions in Melburne, Australia.
    I needed something that would sit well on a shelf, but also offer good durability and anti-static protection. I also have some 2.5" drives from notebooks that no longer work, and some 3.5" drives that won't fit into my current system at the same time.
    I saw some good reviews, so I ordered a 10-pack and they arrived in under a week, with very reasonable shipping. They came with labels and foam padding (which I only needed for some of the drives). I now have 10 cases holding 14 drives, in protected bliss, on the shelf. I can read the label and instantly see which drive I need, instead of peering into anti-static bags. Highly recommended.

  • Unable to erase internal hard disk

    Dear Mac Book Users
    To begin with I got a problem of spinning wheel and grey screen, upon extensive research online i could,nt find any solution and everytime i tried to repair it with disk utility's first aid otion i got the following error:
    Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
    There were a lot of errors wth permissions (upon clicking verify permissions) but the repair permissions button was greyed out.
    Now all that is history and finally the only solution to get rid of the above problem was to back up my data to an external hd (WD-My passport) using the Restore option in disk utility. That worked well and all my data, the whole volume named MACINTOSH HD was copied to external hd and alsi now I am able to boot with this external hd.
    Now the problem is that when i go to disk utility and try to erase the original internal hard disk details of which are as follows:
    Disk Description :
    ST9160314ASG Media
    Total Capacity :
    160.04 GB (1,60,04,18,85,696 Bytes)
    Connection Bus :

    Write Status :
    Read/Write
    Connection Type :
    Internal
    S.M.A.R.T. Status :
    Not Supported
    Partition Map Scheme :
    GUID Partition Table
    I get the error:
    Volume Erase failed with the error:
    File system formatter failed.
    I want to know that has my hard disk crashed and if yes how to confirm it?
    Also if it has crashed, now can i get a new hard disk with a greater capacity (let me know the maximum capacity) than my original 160gb. Are there any things i should keep in mind while buying a new one?
