  • External hard drive documents not read on a MacBook Pro

    Hi all,
    I use my external hard drive to save a document from another  PC computer last week when I plugged it  back on my Mac the documents cannot be  read on a Mac as it says they are not supports by apps software or search for application that will open those files.
    I have all the documents which I copy from my previous Toshiba Laptop which was windows7 but is there way to clean the external drive on Mac without loosing all the document? or how do I format my external hard disk on MacBook Pro?

    You can copy these documents to the internal drive of your MacBook Pro and then, format the external drive. If you want to use the external drive on Macs and PCs, I recommend you to format your external drive on a PC to use exFAT, better than NTFS or FAT32. You can also use FAT32 but it isn't compatible with files bigger than 4 GB, and NTFS disks can't be written on Macs. If you want to use this external drive only with your Mac, you can use Disk Utility to format the external drive using "Mac OS Extended (Journaled)". Read > http://pondini.org/OSX/DU1.html
    Depending on the application you used to create the documents on the PC, you have to install an application that reads these documents. For example, if you created these documents with Office, you can use Office for Mac, iWork or LibreOffice. Each one has got its advantages and disadvantages

  • Suddenly my external hard drive is not read!?

    This hard drive is not one year old yet, and was working perfectly fine till yesterday.
    Last night I just updated my ios and moved from mobile me to icloud.
    Suddenly this morning when I connected my eternal drive, the computer doesn't read it, even in the disk utility.
    I have not dropped or, even moved the external drive since I used last time (two days ago).
    Could it possibly be the updating (which doesn't make any sense to me)?
    What should I do?
    I have all my photos in the external drive, and would not be able to imagine if I had lost them.

    Christine...
    I don't think it's related to iCloud.
    Try posting in the MacBookPro forum here.
    Probably get better results there for troubleshooting the external drive (hardware) then the iCloud forum. 

  • My external hard drive is not recognised on my mac book pro

    my external hard drive is not recognised on my mac book pro

    Hello all -
    similar situation.  Unplugged external hard drive and all to take the laptop on a trip.  On return, I plugged everything back in and keep getting this message:
    Time Machine couldn’t complete the backup to “Iomega_Ext_Drive”.
    Files can’t be copied onto the backup disk because it appears to be read-only.
    You may need to repair or reformat the disk using Disk Utility. If the disk can’t be repaired, you must use a different disk for backups. Open Time Machine preferences to select a different backup disk.
    open time machine preferences.   -
    I tried this and tried "repair" but that didn't work and I still get this message.  Any advice?  thanks

  • External Hard Drive does not show up in Finder

    My external hard drive is not showing up in Finder.
    It shows up in Disc Utility, but I do not have access to it. I have tried the following:
    command-shift c, nothing happens
    confirmed in Preferences/General that external hard drive was checked
    tried another cable
    tried another port on the back of the external drive
    tried to connect through the USB port
    re-started, etc.

    I have same problem after installing OS 10.5.8. Disk utility sees the hard drive, the computer does not. Disk utility says invalid node structure. Volume check failed. Filesystem verify or repair failed.
    That means the directory is corrupt. If you have a heavy-duty 3rd-party disk repair app, such as +Disk Warrior,+ it may be able to fix it. Otherwise, your only option is to erase and reformat the disk. They're not cheap -- Disk Warrior is about $100. And for Leopard, you need version 4.1.1 or 4.2.
    I have not been able to figure out how to start a new topic here, but did find this discussion, which fits me fairly close.
    Just above the list of topics, on the left, is a +Post New Topic+ option.

  • External Hard Drive is Not Showing Up on Desk top?

    My external hard drive is not showing up on my desk top any more. When I tried to reconnect it I get the follow message.
    You have inserted a disk containing no volumes that Mac OS X can read. To use the unreadable volumes, click Initialize.
    Help what should I do? I have 50 GB of music on it and it's never had this problem before.
    Thanks

    Norton has a bad reputation because they have not kept up with changes in the Mac file structure. Norton version 8 is the one you should be using, if you choose to use it. Earlier versions will likely damage your directory, possibly beyond repair by other utilities.
    Any time you use any Disk Repair Utility, it is somewhat of a crap shoot. It may or may not be able to make the repair, and you may or may not lose a few to very many files in the process. The program best respected in this arena is Disk Warrior. If you choose to buy it, pay very close attention to which version you are buying, as the latest version CD (intended to boot 10.3 or 10.4) may not boot on your Mac.

  • External hard drive is not working on airport time capsule even after 7.7.2 firmware update.

    External hard drive is not working on airport time capsule even after 7.7.2 firmware update.
    I have the latest Airpor Time capsule 2gb. I specifically bought it so that I could have an external hardrive set up to wirelessly house my itunes library and movies. When i connect the drive, all i get is that the disk needs to be repaired.
    the drive can works fine when connected to the macbook pro and I have run the verify and repair features in disk utility. I have also reset the airport timecapsule as well following these changes and still no change.
    The 7.7.2 update says that it addressed the usb issue of not showing the drives but there are still problems as I cannot get it to appear.
    Please help.
    Thanks

    How is the hard drive formatted?
    Have you tried using a powered USB hub with the drive when it is connected to the Time Capsule?
    (The USB port on the Time Capsule is borderline as far as power is concerned....you may need to use a powered hub.....even if the hard drive has its own power supply)
    If the drive is formatted correctly....and....it has ample power, it will "show up" when you open AirPort Utility, click Edit, then click the Disks tab at the top of the next window.
    In the example below, my Time Capsule drive is named "Backups" and another drive named "WD Drive" is connected to the USB port on the Time Capsule.
    You should see the name of your Time Capsule drive (named "Data" unless you have changed the name) and the name of the USB drive if you perform the same check.
    What do you see?

  • I got a new computer and backed up my iTunes library to an external hard drive.  The external hard drive is not allowing me to access the drive.  Is there a way to transfer the songs from my iPod touch to my new computer?

    I got a new computer and backed up my iTunes library to an external hard drive.  The external hard drive is not allowing me to access the drive.  I no longer have access to the old computer.  Is there a way to transfer the songs from my iPod touch to my new computer?

    That's a bummer, didn't realize the exHD files were corrupt, esp if you have tried from another PC and not just this new computer.
    You can get purchases from the itunes store transferred from an iPod using these directions:

    If you want everything (meaning non-itunes songs, app data, photos, etc) you need to buy a 3rd-party ipod manager that support iTouch. Here is an iLounge article to start your research:

  • External hard drive is not recognized in Migration Assistantt

    I had my hard drive replaced on my iMac, Mac OS 10.4.11, Snow Leopard.
    I backup my computer using Time Machine onto an external hard drive.
    In Migration Assistant, the external hard drive does not show up. There are no choices to choose to migrate from.
    Any suggestions please!

  • External Hard Drive is not responding

    I started to notice this in the last couple days that my external hard drive is not responding to my imac. I could browse the hard drive, but I would not be able to open any file. And, any application that tries to open file from the drive would fail or would result in "no response".
    The only way I could fix the problem is by unplugging the drive completely and then re-connecting it back.
    My external HD is a 1TB western digital.
    Is this the sign of my external HD failing?
    Thanks!

    How full is the hard drive?
    Have you used Disk Utility to try and repair the hard drive?

  • My external hard drive does not show up on my desktop

    My external hard drive does not show up on my dest top but, does shows in my Windows (vmware fusion) end although I can't see it ob my desktop but, I can eject it properly like any external drive. I have connected it to my windows and ejected properly (per the suggestion of someone on this forum) but, it still doesn't show on my Mac. I see the blue light and hear it running though. I have looked for it in disk utility but, still can find it. I have changed the cable and it still did not show on my Mac. I connected another external drive  and that showed up on my desktop.Any help????

    if it is NTFS then you need Paragon Software NTFS for Mac.
    NTFS volumes are suppose to be read only but in practice external drives don't always mount or work.
    If it is not NTFS then you need more details. Need more anyway.
    PS: this is not a MacBook area, it is Mac 65lbs tower related forum.

  • 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.

    Hi
    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

    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.

  • External hard drive does not shut down

    Hello, When my mini mac goes to sleep my samsung external hard drive does not shut down or dismount properly. when i wake computer i have a error message stating improperly ejected hard drive. It also does not reconize HD until I disconnect and reconnet??? PLEASE HELP Thank you

    My Mini was doing the same thing until I reset the PRAM. With four external drives. They would stop inadvertently with an "improperly ejected" error. Granted two of the drives went bad (6 and 7 years old) but a brand spanking new Seagate and a 3 year old Hitachi drive doing the same. Haven't seen the error since resetting the PRAM.
    If you don't know how to do that, Reboot while holding the Cmd+Opt+P+R keys until your hear the startup chime three times and then release the keys.
