My computer will not recognize my external harddrive

    Question

  • Hello

    The harddrive is verified to work on another computer. 

    The drive does not get power, does not spin up or light up. 
    Has worked previously on the same computer for long periods of time, problem seem to be spontaneous. 
    Does not work when paired with another usb port. 
    Does not show up in any windows program, be disk manager or device manager. 

    Please help its very important as all my work is on it. 

    Thanks!

  • Hi,

    From your description, it seems that you have tried a variety of solutions. Since this issue only occurs in this particular computer and this kind of external hard drive, I wonder whether you enabled the USB selective suspend setting, if you did, please disable the setting.

    If not, I recommend you to try following methods:

    1.  Install the latest Windows Updates.

    • Click the Start button, type Windows Update in the Search box, then click Windows Update in the results pane.
    • Click Check for Updates. After the scan is complete, click Review optional updates.
    • Click the check box next to the updates, then click Install updates.
    • If prompted, review the license agreement, then click I Accept.
    • Follow the onscreen instructions to download and install the updates.
    • If prompted, reboot your computer.

    2.  Reinstall USB controllers.

    • Click Start, then type device manager in the Search box, then click Device Manager.
    • Expand Universal Serial Bus controllers. Right click a device and click Uninstall. Repeat for each device.
    • Once complete, restart your computer. Your USB controllers will automatically install.

    3.  Install your motherboard's latest chipset drivers.

    Meanwhile, please refer to the following article if you need some more information:

  • Looks like a marginal USB case. I would get a different case.

  • Try the steps:

    1. Connect the hard drive to other computers and check.

    2. Connect other USB devices like pendrives or other hard drives to check the working condition of the USB ports.

  • Hey

    1. It does work. 
    2. Those also work.

  • Are you using a desktop computer? If so, the USB port may not be capable enough to provide full power to the hard drives. Check with the rear USB ports.

      

    Additionally, run Microsoft Fixit from here:

  • Hello

    It is a desktop and as previously mentioned I did try other USB ports. 
    The problem suddenly happened, and it has gotten power up until yesterday. 
    I have also tried it with a similar external harddrive, same problem.
