    External SSD randomly disconnects with out warning. Not due to a loose port but Windows.


    I have a SABERENT external NVME enclosure holding a Evo 970. After a while it will just disconnect. When I click on the hidden icons thing it will appear for a second then disappear and give a windows malfunction error. I have tested it on another Windows computer and a Mac and they work seamlessly there.

  2. External SSD recognized as HDD in Windows 10

    Hi,



    Thank you for writing to Microsoft Community Forums.



    I understand your query related to External SSD showing as HDD when connected to the PC using USB 3.0 port. For further clarity on the issue, please respond to the questions below.



    1. Have you tried connecting the SSD to any other PC?
    2. Are you using any converter to connect the SSD through USB 3.0 port?
    3. Are you using a RAID configuration?


    I have researched on your query and found that the SSD that you are using is an internal SSD drive, in this case I would suggest you to try updating the Intel Rapid Storage drivers from the

    intel website
    and see if that helps.



    In addition, this issue can occur if the SSD is connected to a SATA controller that is identified as RAID (SCSI). I would suggest you to try connecting the SSD to a SATA port that uses AHCI controller such as Intel SATA controller/chipset.



    Please get back to us with the detailed information to assist you further.

    External SSD not recognized as SSD in Windows 10

    Hello community!

    (this topic applies to Windows 10 and Windows 8.1 equally)

    my question concerns an external 240GB SSD drive connected to my laptop via an USB 3.0 port. The SSD works fine, but when using the "Optimize Drives" utility, the drive is listed as "Hard Disk Drive" under media type. As stated by almost all SSD manufacturers,
    standard defragmentation on a SSD can actually harm the SSD and over time reduce performance and life-cycle. A test revealed that the optimization for the external SSD is actually performed like on a regular HDD and the TRIM command is not used. This would
    also indicate that the regular TRIM commands issued by Windows are not applied to the external SSD drive either. Short of turning off automatic optimization, is there a way to tell Windows that this is an SSD drive and to treat it as such (regardless of
    the information provided by the disk- or case-controller) ?


    See also picture attached -

    Drive C: is a SanDisk SDSSDXP480GR131 SSD drive built in the laptop and recognized properly as an SSD.


    Drive F: is Lite-On LMT-256M6M SSD drive attached via one of the USB3.0 ports and classified as regular HDD.

    Primary monitor blacks out after disconnecting from external

    Hi Oscar,



    Thank you for writing to Microsoft Community forums.



    • Are you aware of any changes that happened on the computer prior to this issue?


    This issue could be due to the display setting corruption that only affected the primary display when disconnected from the secondary.



    I suggest you to try the steps listed below and check if it works for you:

    • Press ‘Win + R’ keys on the keyboard together to open the Run dialog box and type the following into the Run box:
      appwiz.cpl
    • Uninstall Intel HD Graphics Drivers and exit
      Programs and Features.
    • Right click the Windows icon on the taskbar and choose
      Device Manager
      .
    • Expand Display Adapters and right click on
      Intel HD Graphics Display Driver.
    • Click on Uninstall and check the box
      Delete the driver software for this device.

    • With the external monitor connected, reboot the machine.
    • Once the machine boots into the desktop, disconnect the external monitor and check if the issue persists.


    Hope it helps.
