    External SSD loads/mounts and then immediately unloads/unmounts


    I'm desperately trying to mount an SSD plugged into an external enclosure on my laptop, but every time I try, it loads (4 partitions), then immediately unmounts. No error message is given -- all I see is basically "has been loaded" followed by "has been unloaded".

    I know the SSD is at least reasonably good (based on SMART testing), but I want to run disk check on it to be sure. And it mounts acceptably on my desktop, where it's the system disk for 64-bit Win 10 Pro (1903). The problem there is that it runs unacceptably slow, so slow that chkdsk never really gets started (and all other apps run slow, too). Thus my need to mount it on my laptop. The external enclosure is rock solid -- the best I've ever had.

    What's going on and how can I fix it?

    :)

  2. Windows 10 shutdown doesn't unmount despite......

    Hi,

    Thank you for the update and I apologize for the late response.

    I appreciate if you could answer few questions to narrow down to the issue.


    • How exactly you are trying to unmount the drive. Is it through Command prompt or from Disk management?

    • What exactly happens when you try to unmount?

    • Did you receive any error message while trying to unmount?
    I suggest you to try the steps given below and check if it helps.

    Please close all the Windows before trying the steps.


    • Open Disk management.

    • Right-click the mounted drive that you want to remove, and then click
      Change Drive Letter and Paths.

    • Click Remove, and then click Yes.
    Hope the information helps. Let us know if you need further assistance. We will be happy to help.

    Thank you.

    USB SSD keeps unmounting when putting laptop to sleep

    I have a bus-powered external USB hd (WD MyPassport Ultra) that does not unmount when putting the computer to sleep.

    My external SSD however, is still unmounting when putting the laptop to sleep.

    Windows 10 apparently does not know how to properly deal with external SSDs?

    My external SSD is a Samsung T3 512GB

    USB SSD keeps unmounting when putting laptop to sleep

    I have a Samsung SSD T3 connected via USB (3.0) to my Win10 Dell XPS 15.

    Whenever the laptop goes to sleep the SSD unmounts and is not available when I wake the laptop up again.

    What is required to keep the USB SSD Drive always mounted?
