My external hard drive is not recognize on my mac

What software can I get to try to back up the things that are on my WD external hard drive that is not being seen on my Mac or through time machine.    My hard drive is spinning but not recognized.

I am curious if you ever got this problem fixed. I bought a WD external drive a month ago and recently my iMac will often not recognise it. The light on the drive is on, but it doesn't seem to mount.

  • What should i do if my external hard drive is not detected by my mac

    what should i do if my external hard drive is not detected by my mac?
    need to have the files saved on it and be able to backup via time machine

    Hi:
    Here are some of the options I've read about on here that may or may not work:
    1. Reset the NVRAM as it may need to be reset to recognize the drive. See below:
    http://support.apple.com/kb/ht1379
    2. If the drive is a USB drive, put a USB hub between the drive and the unit. As ridiculous as that may sound in some cases it works.
    3. If you have some types of hardware problems and want to test them this works:
    http://scsc-online.com/Scannerz.html
    That's a test tool only. It isn't going to fix anything just diagnose a bunch of possible hardware problems and it costs money, too.
    What format is the drive in? Is it a Mac native format like HFS or is it some other format, like NTFS or FAT?

    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

  • My external hard drive is not working on my mac.

    I have tried all options available such as going on finder and making my hard drives visible and disk utilities

    Basically my external hard drive would not eject so i force quit it and the hard drive does not come up at all anywhere on my mac pro OS X version 10.9.4 and it isn't visible in disk utilities no and it doesn't say format either and i have tried it on a windows computer it does not show on their either. the format is Fatdos i think so i can use it on windows and mac and i cant see anything in system reports and yes it is connect by a USB. also it isn't making any noises either

  • How can I recover file that are on my external hard drive but not showing up on mac?

    I have copied pictures and home videos from an old hard drive to my newer, larger hard drive. And now, i can't see any of the videos when i open my Seagate 4TB BackUp Plus drive on my mac. Someone Plz save me!!!!!

    Open Disk Utility in Applications/Utilities.
    Check format for the Seagate.
    I'm guessing you didn't format the drive for Mac.
    You might need to reformat. This will erase all contents on the drive. After reformatting, go back to the old drive and copy over the files again.
    Format the external drive as Mac OS Extended (Journaled) - Partition Map Scheme: GUID

  • My external hard drive is not recognized by my computer.

    My external hard drive is not recognized by my computer. I used it earlier and it was fine however my computer froze and I unplugged my hard drive without properly ejecting it. Now when I plug it in nothing pops up. I've tried on three different computers and no luck. I hope this is fixable! Please help.

    Care to share which OS you are using?

  • 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?

    External hard drive does not show up in imovie.

    Hi,
    Welcome to the Discussions.
    The drive's directory is damaged and as you found Disk Utility isn't equipped to repair it. You need Disk Warrior or Tech Tool Pro.

  • 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:
    http://support.apple.com/kb/HT1848?viewlocale=en_US
    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.

    Is this the sign of my external HD failing?
