External hard drive not shown in the capitan utility_EI drive

I spoke with the Apple technical support for several times. My problem:

(1) a disk external drive 2 TB of work works well under windows, old Mac (2012); just revealed in the new Mac EL capitan for the first month;

(2) never appeared in DISK UTILITY;

(3) "command + Option + P + R' does not work.

It seems that APPLE has denied this defect in their product.  It's completely a waste of money.

I want a refund! Please, I beg you.

Were not apple, and any problems you encounter with a 3rd party device on your hardware Apple will not be covered by restitution by Apple

Read the EULA, go to section O. If you want a refund speak to the manufacture of the drive.

If the drive needed 3rd party utility delete it, no matter what party utility 3rd by the reader to work inside the BONE is not recommended.

  • Drive external hard Mac has shown in the past but does not now show in disk utility. How can I get it back?

    I'm going crazy trying to find an answer to this question! My external hard drive has shown in the past but not now shows in disk utility. My OS is X El Capitan.

    I tried to turn off my computer then unplug my external hard drive waiting for 30 seconds back on my computer and plug my hard drive with no joy.

    I hope someone can help.

    Hi willy of San Jacinto.

    I understand that your external hard drive is no longer seen by your computer. I know it's important to have a good backup location, and for that to work, I am so happy to provide assistance with this.

    Read this article on troubleshooting USB devices:

    OS X El Capitan: If a USB device does not work

    If your computer is yet to see the hard drive after following these steps, it would be interesting to test this drive on another computer if available. If you continue to have problems, I suggest contacting the manufacturer of the hard disk on a hardware failure possible.

    Thank you for using communities of Apple Support, cheers!

  • drive external hard do not appear in the folder tab.

    Please specify.

    If some of the images were imported from an external hard drive, you must select one of these specific images > click right/control click > select 'go to the folder in the library.

    If it still shows the office, this would mean that you have chosen to copy when importing and images have been copied on the desktop instead of being added via the hard disk external.

  • I've just backed up with an external hard drive for the first time, but my profile with my folders for photos, documents, and movies are not there

    Hello

    So, I finally got an external hard drive. I formatted for Mac (the device has been verified as being correct), and then he started to do a backup, which stated that a full backup would take 95GB. However, it only supported 19GB.  When I have my 'open' backup drive, I saw that only 'Macintosh HD' received support upward, not my user profile with all my folders containing documents, photos, movies, etc...

    I'm quite confused, because I thought that it would save.  I plan on Snow Leopard update to El Capitan, but if something is wrong or I don't like, I'm afraid that I won't be able to restore all my personal files - but only the applications that are on my Macintosh HD.

    Should I delete everything in my backup disk and try again?

    This is an image of what's inside my external hard drive:

  • After the upgrade to El Capitan I can't write on the external hard drive to NTFS format more

    I have an external hard drive formatted in NTFS, I used some Mavericks and could read and write on it without problem, after I installed El Capitan today I can't do more, not this external hard drive is read-only. The problem is that it is full of my data and I can't just format as journaled. What I can do and why it worked fine before?

    You need to upgrade or replace the software you used to write on NTFS volumes and should put a copy of your data to a second drive in case one you have fails for any reason unrelated.

  • External hard drive in the Device Manager but not in disk management

    So I have this external hard drive Western Digital 1 TB. I've had for over a year now and it was working fine. I would like to trade my XBox 360 and the computerregularly. Then one day I brought home, plugged into the computer and nothing. My friend and I couldn't understand anything. We have gone as far as removing the hard drive and put it directly into the computer. I have reviewed, that he has lost.

    Then yesterday, on a whim, I tried to connect it again to the USB port. It is presented in the Device Manager but says that its drivers have not been installed. Then, I changed the USB ports on the back of the computer and as if by magic, that this is once again. I had full access. Stupid (and you can see where this is going) did not immediately transfer anything off the hard drive. I'm looking for an image and listen to a song off of said hard drive when the drive went suddenly not recognized.

    I can see now the reader in the Manager of devices under disk drives, and USB devices. However it does not appear in the disk management window. And Yes, I checked as well the Productdocumentation upper and lower, that it is not listed. Go to the area where you assign drive letters not shown not be. Normally this is E:.

    I also tried to remove the UpperFilters registry in regedit. It was not to remove LowerFilters. Obviously, that didn't work or the other.

    I tried several cords and all my USB ports with no luck either.

    I went on the WD Web site, but they do not offer anything other than a partitioner that I would save rather than as a last resort as there are a number of things on the hard drive I want to save.

    So it's not like it's a new HD to be partitioned or an old man who comes out crapped. I know there's the data I just need to get home long enough to get what I need. Maybe I missed my window, but maybe I did not. Maybe someone can help. I'm at the end of my mind on this thing.

    Sounds like a problem of partition (maybe corrupted partition tables) if the device is recognized, but not the 'disk '.

    There are recovery/repair partition about tools.  Western Digital actually have some but I think that they are made for internal drives.

    If I were you, I start with WD and start looking for partition recovery/repair tools.  If this is the problem then it is the right kind of problem and you using the right type of solution can fix it easily.

    If this is not the case, some data recovery tools can help you recover some files even if you have to recreate a new partition, although I wish you much luck with this approach!

    Good luck whatever you try and make sure that you do not overwrite the what partition information, you have without making backups (many partition edititing software will offer backups)

  • External hard drive does not work. Is there another way I could solve the problem without formatting the external hard drive?

    My external hard drive works. I tried to plug and when I tried to open it, it says to format the drive until I could use it. Everything works well as when I plugged the USB icon shown on the screen. When I check the disk management, it showed that the partition of the drive is there.

    I tried to change the drive letters, but still having the same problem. I also tried to run the disk check on the command prompt and the properties of the drive, but it still can not because there is error popping up saying that the disk check cannot be performed because Windows cannot access the disk.

    Is there another way I could solve the problem without formatting the external hard drive?

    I tried the first step in troubleshooting the hard drive, but it gives a
    error in saying that "hardware changes might not have been detected.

    So I tried the second method, and when I click on the "Check now" button his
    gives an error saying that "the disk check cannot be performed because .
    Windows can not access the disk".".

    So is there any other way or option?

    Thank you

  • External hard drive will not mount after the update of the Sierra

    Hi, I have an a Segate 1 TB external hard drive that I have with my MacBook Air. After upgrading to Mac OS Sierra, he refused to climb and is therefore invisible in the Finder. Disk utility detects the drive in NTFS initialized and said that all the space has been used. I tried to mount it first through disk utility, but it did nothing. Then I tried via terminal, but he returns "failed to mount. It worked fine before and also works very well on a MacBook Pro running Yosemite. It may be nothing to do with the player, as all files are intact when it is connected to the other Mac. Also, I restarted in Mac utilities and run from there disk utility, and it detected the drive, mounted and fully initialized, with the right amount of space being exhausted.

    I am looking for a solution that does not copy the files off and reformatting if possible, but I'll give it a go, if it comes to that. Thank you very much.

    Most likely your Seagate drivers are not updated.

    NTFS is most likely the culprit here.

    Go to the Seagate site and download and install the latest drivers for your drive and NTFS.

  • My external hard drive will not go up and I'm not sure what the question is

    My external hard drive will show up in disk utility, but not of viewfinder. I tried to hit "repair disk" and he says it will take 4 hours, but after a while, that he's finally going to say that it is impossible to repair the disk and I need to make a backup.

    Help?

    Almost always, the question is quite simple: the hard drive is faulty or has failed. So I hope that you have a backup of everything that is on, it is absolutely essential.
