my laptop does not recognize one of my external hard drives, it is used to. If I open Device Manager it is there and it says that this device does not work, anyone got a popular response.

Make sure it has a drive letter assigned to it.

  • My used external hard drive appears now as (g), it appears as (h). How to switch this back?

    I plugged my Ipod without my connected external and now the Ipod 'stolen' label (g). No matter if its connected or not it (g) Ipod and external shows like (h). How to pass the external back to (g)?

    Hello

    Step 1: Connect an external hard drive (before iPod conneting or any other external device) and then check if the G drive letter is assigned. If the G drive letter is already used by any other device, then it cannot be attributed to other devices.

    Step 2: If none of the devices are using the G drive letter and then try to change the drive letter.

  • Why my external hard drive appears twice in Lightroom?

    My folders to Lightroom 6 are broken down into '2015' and "2016." However, under the section of the folders on the left, it lists my external hard drive twice, by 2015 one of them and 2016 in another. It wasn't a big deal, but when I went back and added the "Oct" file in 2015, he put it under the folder 2016 for some reason any. Folder does not exist "Oct" less 2016 on my hard drive, just in the case of 2015.

    I tried to move it and it won't let me (because, ironically, it is said there is already a file named "Oct" that exist - I know there are, that's why I want to move it where it belongs!) ». I don't understand what is happening. Very frustrating. Should I delete something and try again? Thank you

  • External hard drive and Vista

    My 360G Seagate external HARD drive appears with 89G exhausted. I haven't saved anything yet and the only things about it are the installation files accompanying matching a few hundred KBs. I should have near the available 360 G set.

    What is the problem and how do I do about it?  Thank you

    I think I can find some possible reasons. Through each file in the drive installed for herself, I came across a huge amount of redundant junk - I call it junk because there are 9 'levels' of history, each with a kind of mirror for the C: drive, but with only random selections nonsense. For example, each level has C:/programfiles, but there maybe 3 files, another 10, etc.. Most is not the story of used recently.

    Yesterday, I used Cleanse Uninstaller to uninstall AllMediaGrabber in C:\. He was earlier listed in one of the program files on drive H: so I clicked it and it opens as if I had never uninstalled. I ran Cleanse again using the path H:, he completed the uninstall, I come back and AllMediaGrabber is still there.

    I never activated or whatever it is set up so far, so I guess I find better Seagate how to reformat - what happens if a virus gets in there and is the same as tenascious as the simple AllMediaGrabber, I think that would be a bear to manage. I did not sign for all this, I wanted only to additional disk space.

  • New computer that is running Windows 7 does not recognize my external hard drive completely

    I bought a new PC with windows 7.  I use an external hard drive with USB to move the files from the old PC (XP) to the new PC.

    When I go to 'my computer' focus on the external hard drive storage devices is not displayed.

    When I go on my devices, the external hard drive appears.  When I look at the details on this HD and pushes to execution, windows States there are no problem.

    The clues of what I need to do so that I can look at the files on my external hard drive?

    Thank you

    Hi Andre,

    I've struggled for some time with this one, here's how I finally solved it.  Apparently, USB drivers for mass storage devices was not compatible with my external hard drive.  I simply uninstalled the USB drivers for mass storage devices, then plugged my hard drive.  Automatically downloading appropriate drivers, and I was good to go.

    Just thought you might want to know that.

  • Drive external hard drive does not appear under "devices."

    Hello

    I just updated my OS to Sierra of MacOS. I have connected my external hard drive (HDD) and it does not appear under "Devices" in my Finder window. It worked fine before the update.

    I use a MacBook Pro (end of 2013), currently running MacOS Sierra (Version 10.12). My external HARD drive is a SeaGate Slim SL Media (500 GB).

    The external HARD disk appears in disk utility application. He also appears on the about this Mac > system report > USB. I don't know what the problem is, the external HARD disk is identified but does not appear for use in the Finder window.

    I read that it could possibly be in mode 'sleep' and putting the MacBook to sleep (while it is plugged into the external HARD drive) and it to wake up again should solve the problem. However, it did not work. No more restarting my MacBook. It was mentioned in another post that it may require extra power, so I attached power adapter and again, without success.

    I do not want to clear the contents of the external HARD drive.

    Is there a way to get my external HARD drive works as expected with my MacBook?

    Thank you much in advance.

    I also have this problem.

  • Bought the new computer windows 10, itunes has changed location of support for external hard drive. The music does not appear in itunes.

    BOUGHT NEW COMPUTER WINDOWS 10, CHANGED ITUNES MEDIA LOCATION FOR EXTERNAL HARD DRIVE. THE MUSIC DOES NOT APPEAR ON ITUNES.

    Changing the iTunes media folder location setting affects only where new additions to your library will be stored.  To use a disk external drive to store your library complete (and assuming that you have access to the original data of the library on an old computer) you must copy the iTunes folder, by default in C:\Users\username\Music, on the external drive - structure library and its records should be like this:

  • After Vista update cannot find the external hard drive, AutoPlay does not work, and new unusable disk appears under my computer

    After Vista update cannot find the external hard drive, AutoPlay does not work, and new unusable disk appears under my computer. Also I can't 'manage' my computer because I do not have "permissions". I tried a fix he 45071 and it did nothing.

    Applications, (Norton and McAfee) (including free evaluation versions are notorious for not not upgrade (or uninstalling) itself.) If NIS has been installed for 3 years, you have NIS update at least once and maybe twice (e.g., NIS 2009 > NIS 2010 > NIS 2011).

    1. download the Norton Removal Tool, save it to your desktop: ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. After completing some you have a copy of your handy product key, uninstall all Norton software (including LiveUpdate and everything Norton Add ons) viaControl Panel | Programs | Uninstall a program (or Control Panel |) Programs and features, if you are using the classic view).

    NB: Now you're "working without a net": no to ANYTHING else online (e.g., navigation, reading e-mail, chat) until you have completed step #7 below!

    5. right click on the file that you saved in step #1 above, and then select run as administrator.  DO TAP not your keyboard until the race ends, then restart.

  • "My external hard drive does not appear in Windows Explorer and cannot open 'Help and Support', an error message" Windows cannot open help and Support because a system service is not ongoing.

    Original title:

    Everything was fine until yesterday. Juice now, when I plugged the external HD into the USB port it does not appear in the 'my computer' window. It is recognized by the computer as it is present on the list of the "Disk Clean Up" and it also appears when I click on ' Safe Remove Hardware ' on the taskbar. But if she does not appear in the 'my computer' window I can't work with it or don't even know what it I have arquived in it.

    Trying to find a solution, I realized that same 'information system' to 'System tools' is also not available. Pops up a window saying that "Windows cannot open help and Support because a system service is not ongoing enforcement. " To resolve this problem, start the service named help and Support '. OK, I tried to open 'Help and Support' ' Start Menu ' and the same window appeared again to "not have a system service that runs". I don't know what her soul precisely and I have not the slightest idea of what I need to do to correct this 'disappearance' of Service 'system '. There is nothing without the appearance of HD in the window of thw work? Everything else works fine and the calculation is virus-free. What should I do?
