Windows 10: USB Disk Drive not recognised

Hi


I have two 1TB Toshiba USB Hard Drives. Both work on my old Dell laptop but only one works on my relatively new HP machine. Both are running Windows 10

It shows in Device Manager but not in Disk Management or System.

Clicking the USB eject icon on the taskbar displays an External USB 3.0 device but it does not have a drive letter associated with it. Selecting 'Eject' message displays the 'Safe to Remove' message.

I have tried:- using different ports, using a powered USB hub, updating the driver it was at the latest level removing a re-installing the device, re-booting the machine and performing a windows update

I have downloaded and run the Toshiba Storage Diagnostic Tool and that PASSED


I am stumped so any help would be appreciated.

Thank you in advance

:)

Hi Nicholson,

Thank you for your interest in Windows 10.

I suggest you to follow the methods below and check if it fixes the issue.

Method 1: Run Hardware and Devices Troubleshooter

Follow these steps to run Hardware and Devices troubleshooter:

  Control Panel.

  Select Troubleshooting.
  
• 
  Select View all on the top left corner.
  
• 
  Click Hardware and Devices.
  
• 
  Follow the on-screen instruction to run the troubleshooter.
  

Method 2

I suggest you to check if the disk is listed in Disk management utility. If it is listed, run an error check to see if there are any corrupted files causing this issue.
Refer these steps:

• 
  Press Windows key + X, select
  Disk management.

  Right click on the drive and select properties.
  
• 
  Under tools tab, click on “Check” button under Error Check.
  

Method 3: Uninstall and reinstall USB drivers

Follow the steps to uninstall the USB drivers:

• 
  Press Windows Key + X key and click Device Manager.
  
• 
  In Device Manager, double click to expand "Universal Serial Bus controllers".
  
• 
  Right click on the Host Controller, click "Uninstall" and click "OK".
  
• 
  Select the option to Delete driver software.

  Uninstall all items under "Universal Serial Bus controllers".

Try to access the computer manufacturer's website and download the latest chipset drivers for your computer and install the same.

USB drive showing as Local Disk on Windows 10

Harun,

Thank you for the additional information. I have been thinking about this further and doing a little searching for any similar problems.

The reasons that I do not think that the issue is with the USB Flash Drives but rather with the PC are:

• The USB Flash Drive was successfully recognised on the PC as a USB Drive by an application on 16th May
• On 3rd June, I noticed that the application did not recognise that a USB Drive was inserted and that the USB Drive was being shown as Local Disk.
  
• I have since sampled ~5 USB Flash Drives (of varying ages) and 2 SD Cards - all are shown on the PC as Local Disk.
• On my Laptop, all these USB Flash Drives are shown as USB Drives and the SD Cards are shown as Removable Devices.

The only changes to the PC between 16th May and 3rd June are the updating of several drivers through Auslogics Driver Updater (including update of driver for USB Mass Storage Device; reverting to previous version of this drive made no difference) and disconnecting
the PC to move to another room.

I also noticed that under events for the USB Drives, there were "Device ... was not migrated due to partial or ambiguous match" events.

Searching, I found an entry on the Microsoft Forum:

Devices "not migrated" after Nov. update: Devices "not migrated" after Nov. update.

A Microsoft agent suggested that this could be due to the chipset drivers having problems and to try uninstalling and re-installing the chipset drivers. However, the originator of the question did not try this suggestion.
