Windows 10: USB drive not accessible in Win10

I have several drives that I use for backups. I am finding that when I unplug and replug them that I get a dialog the they are not accessible, access denied. I do use the hardware eject to remove them safely. When they are plugged in, they come up with the previously assigned drive letter. I have been able to reassign the drive letter, making them accessible, and then reassigning the original letter. This appears to work sometimes, but then eventually no longer works. Sometimes I can reassign yet another drive letter particularly on that has not been used before and then the original and that renders the drive readable. Now, even that does not seem to work.


Any ideas appreciated.

USB Drive Access Permission

Let's try a different approach. Since the updating the driver does not work, see if changing the Security settings on one of the USB drive. Follow the steps below:

• Right-click the USB's drive on File Explorer and select Properties.
• Click the Security tab.
• Select an Owner/User and click Edit.
  
• Check all the options on the Allowed column, select OK and then Apply.

Update us on the result.

 

Can't Access Either of My External Drives After 14393

Hi Michael,

To better assist you with your concern, I would like to ask if you're getting any error messages when accessing your external drives? If yes, can you provide us with the exact error message?

As an initial troubleshooting, we suggest you to follow the steps below:

• Go to Device Manager.
• Click on USB Mass Storage.
• Right click on your USB, and then click on Update Driver Software.
• Once done, check if you can access your external drives.

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
