My WD external hard drive is no longer show up on my computer-it no longer recognizes it.

I have a WD external hard drive for sometime that I have been using to backup my computer and generally keep some of my bigger things on it(such as degital copies of movies). But suddenly one day my computer won't recognize my external hard drive when I went to plug it in. The light on it that is on when it is plugged in is on when I do plug it in, yet I can't actually find and acess my external hard drive. I don't know whats wrong and how to fix it so I can continue using my hard drive.

dead sata bridge card. very common problem.

  • How do you erase an external hard drive which will not show up on your computer?

    I bought a LaCie porsche design 2TB external hard drive  from the Apple Store to use with time machine on my MAC 2 months ago. It will no longer show up on my desktopn. After speaking with LaCie, they sent me a replacement. However, I have to send the brooken one back to them and since we could not erase it or anything on my Mac is there anyway to erase the hard drive before sending it back to them with all my information on there?

    I know. But after Yahoo, Target , Neimans and others. But I agree. They even sent me a more expensive replacement as they did not have my model in stock and is backordered. So, a win win situation. I was impressed that the tech person spent about an hour on the phone with me trying a variety of options. At first, they were going to charge me shipping- but then she changed her mind and shipped the replacement 1 day fed ex. I guess that is why I always buy LaCie vs others. My older LaCie which I still had but was smaller- I plugged in and did a back-up and I had just enough room on it so I have that for safe keepings now as well.
    Thanks again for your pleasant response. I guess I need to limit my profile to "registered members" only. I hope Apple monitors these discussions and people's responses periodically.

  • My WD external hard drive will no longer show up on my Macbook pro.

    My WD external hard drive will not longer show up on my macbook pro.  The light turns on and you can hear it running but it won't show up either in finder or in the disk utility.  This happened a while ago but I really want to get all my photos off the hard drive.  Is there anything I can do to get my computer to read it again or get my data off of it?
    I don't have access to another Mac to test it. 
    Thank you

  • My external hard drive will no longer connect to my macpro......any ideas on how to solve this problem??

    My external hard drive will no longer connect to my macbook pro via FW800........Any ideas on how to solve this??

    Reset the SMC, see this Apple note: http://support.apple.com/kb/HT3964
    Also reset the PRAM:
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    In most cases, those two actions will fix the port issue. If it's still an issue, you may need to see if the external hard drive can connect to another system, to ensure it's not having problems.

    Hi rivraff,
    If you are having issues mounting an external hard drive volume, you may want to see if it shows up and/or can be repaired in Disk Utility; you may find the following article helpful:

    Once I upgraded to ML, I'm now finding that my Seagate Free Agent external hard drive is no longer being backed up by Time machine.  Do I have to wait for Seagate to update their drivers for this hard drive?

    I tried your suggestion, and it's been giving me the message "Preparing for Backup" for the past 8 hours.  Does this mean TM is backing up my hard drive?  I'll give it a few more hours, but if nothing else happens, I'm not sure what else to do.  I'm not sure if there are any new external hard drives that are compatible with ML yet.

  • How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility

    How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
    Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
    After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
    So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
    I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
    I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
    I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
    Are the files lost forever or can i recover them by going to a shop or using a software?

    Thank you for responding.
    This might sound stupid since i'm not really knowledgeable with Macs,
    but since all my files were moved from my mac computer to the external hard drive,
    is it possible to recover those files through my Mac - like recovering deleted files? 

  • Windows not recognizing my time capsle - I just purchased a new computer that runs windows 8 and it doesn't want to recognize the time capsule as an external hard drive (ie doesn't show up under my compter).  I've downloaded airport utility...

    I just purchased a new computer that runs windows 8 and it doesn't want to recognize the time capsule as an external hard drive (ie doesn't show up under my compter).  I've downloaded and run airport utility, but it seems to have a hard time finding the time capsule...maybe one out of 10 times it will find it.
    What's more, when I look under network infrastructure under the control panel, it shows my Broadcom ADSL centurylink Router...so I'm wondering if my modem/router combo is overriding the router function on my timecapsule and the time capsule is not being used as a router...
    Any help much appreciated!

    In this case the TC should be in bridge mode.
    Win8 is still problematic. Try using ethernet instead of wireless. I think the drivers are poor still and it is well worth having a try via ethernet if you haven't already.
    Otherwise you will need to wait for apple to release bonjour for windows 8 and airport utility.. which is not out yet.
    Also make sure the windows is set to home, not work or public.. even turn off the firewall.
    Open windows explorer and type the TC ip address into the address bar.. (none of which is perhaps the same.. I gave away windows at vista.. shudder)

  • My external hard drive is no longer connecting. I was getting a message every time I plugged it in that it needed to be reformatted so I tried to do so and now when I plug it in the computer does not recognize it. It only shows up in utilities...

    Hey guys, I need some serious help. I have an external hard drive, iomega which apears to no longer work; I am sure it is something I have done and I cant figure out what! I am certainly not a computer expert and am in Turkey so I dont have access to a MAC store for assistance or anything like it. Yesterday I plugged my external hard drive into my MacBook and got a message telling me to refotmat. I looked up how to do so and through disk utilities thought I did it right. Now when I plug in the hard drive my laptop does not pick it up; the only place it shows up is in utilities, the same place I tried to repair and reformat. When I am utilities it looks like I have 2 hard drives, one under the other. One tells me the description of the hard drive, the other doesnt really tell me anything. So I erased both of them and I think that is where my problem is. Any help on how I could fix this? I tried to "mount" the one that is not "mounted but it didnt work....I dont even know what that means!!! Help!

    When you erased the disk did you select Mac OS Extended Journaled as the format option?

  • IPhoto library on external hard drive will no longer open

    I'm hoping that someone will be able to point me to a simple solution to my problem...
    I'm running iPhoto 9.6 on a  MacBook Pro (Retina, 13 inch, mid-2014).  The OS is Yosemite 10.10.1.  Because the flash storage is only 250GB I have my main iPhoto library (146GB) on a partition of an external 1TB Lacie Rugged drive.  The external hard drive also has partitions for Time Machine Backup and SuperDuper Bootable Clone.  I have a separate, much smaller iPhoto library on the MBP which contains recent photos.
    Yesterday I failed to reconnect my MacBook Pro to the power source when I put it back on my desk.  The result was that the battery went below 5% and the MBP turned itself off and also ejected the external hard drive (some time after I reconnected the power cable there were dialog boxes on my screen informing me that each of the three partitions had been ejected incorrectly).  I waited until the MBP was fully charged before I tried to open my 'main' iPhoto library on the external hard drive.  I received a message that the library would have to be upgraded to work with the computer (very odd, because it had already been upgraded last October when I upgraded from Mavericks to Yosemite and has been working without any real problem ever since then).
    After some hours when the only message on the screen was 'Rebuiding Thumbnail Caches' I pressed Cmd+Option+Esc I saw that iPhoto was 'Paused'  - that message subsequently changed to 'Not Responding'.  I 'Force Quit' iPhoto but the iPhoto library will not open at all from the external drive.
    As a test I quit iPhoto and re-started using the Option key and chose to open the iPhoto library which is on the internal drive and it opened without any problem.
    I recall that it used to be possible to fix this sort of thing (perhaps not) by trashing the com.apple.iPhoto.plist file, however, I don't seem to be able to find it :-(
    I'm really at a loss as to how I should approach this problem and I would be very grateful for any suggestions that can be offered.
    Cheers

    Further update ....
    I downloaded and installed iPhoto Library Manager and then chose Library - Rebuild Library.  Unfortunately, when it had finished the result was 0 images in any file or folder.  I checked the log (which is incredibly long) but here's the beginning of it which seems to indicate that the problem is that an essential file is missing -

    After this each entry has a dialog that basically says the image file is missing from /Volumes/Pictures/iPhoto Library.
    As mentioned in an earlier post I do have another iPhoto Library on my 2008 MacBook.
    Can someone advise the best way to proceed?  I'm thinking that I should erase the partition of my external hard drive that is called Pictures and then connect the external hard drive to my 2008 MacBook and simply drag and drop the iPhoto Library to the Pictures partition.  IIRC, that's the way I moved the iPhoto Library last October when I bought my new MacBook Pro which didn't have enough storage for me to be able to store my iPhoto Library on the MBP.  I could then reconnect the external hard drive to my MBP and the iPhoto Library should reappear, shouldn't it?
    Looking forward to more input ...

  • Updated to 10.4.10 and external hard drive is no longer readable...

    I was asked to install a few updates today when I booted up. I d-loaded like a good little soldier and installed and now my external Seagate drive is no longer readable. The prompt asks me if I want to initialize, ignore or eject the drive.
    Here are the updates...
    1.) About iMac Software Update 1.1
    This update provides important bug fixes and is recommended for 20-inch and 24-inch iMac models with 2.0, 2.4, or 2.8GHz processors.
    2.) Keyboard Software Update 1.2
    3.) iTunes 7.4.1 for Mac
    4.) Compatibility Update for QuickTime 7.2
    Is there anyone that would know why this is happening?
    Thanks,
    John

    It's hard to imagine why those updates would affect your Seagate drive - the iMac Software Update 1.1 was simply an update to the graphics drivers, and the other ones are self explanatory. Have you looked in the system logs to see whether there is any clue in there as to what is failing? (Open the Console application to view the logs).
