Windows 10: What would cause W10 to loose USB memory Stick Drive assignment ?

What would cause W10 to loose USB memory Stick Drive assignment ?


That's what happened today. Example for the last 7 years (Even before W10), I have 3 USB Memory sticks that I backup Quicken to every day (Except Weekends). They always have mounted as "F:" drive. Today W10 knew it was there, but never assigned a drive letter ? This also holds true for all of my other USB sticks. However any rotating drives in USB 3.0 enclosures are assigned their correct drive letter.

There were no fixes between yesterday when they all worked and today ?

The fix is to mount the USB Stick & assign a drive letter via Diskmgmt !

Any idea on how this could happen or what could cause it ? *What

:)

 

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.

 

Installing windows off of a USB stick

Step By Step from vista:
From admin cmd prompt

1. diskpart
1a. list disk
2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)
6. active
7. format fs=fat32
8. assign
9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

 

Windows 10 Problem with usb port and old memory stick

Hello Steve,

Thank you for posting your query on Microsoft Community.

We regret the inconvenience caused to you. We will be glad to assist you with your issue.

• Does the issue occur when u try with different USB drive?
• Did you install all the pending Windows update?

I suggest you to first try and check with different USB Memory stick and check if the same issue occurs. Also try using your current USB memory stick in different USB port and check. Also install all the pending Windows
updates and check. You can also try using the Memory stick on another system and check if its working fine.

For now, you can try updating the drivers of the Memory Stick and check if it helps:

Follow the steps to update drivers from the Device Manager:

1. Right click on
Start button, select Device Manager andEnter.

2. Find the drivers which needs to be installed and also see if there are any warning symbols. If yes update the drivers.

3. Right click on the Memory stich device and click on
Update driver.

Let us know the status of the issue. We will be glad to assist you further.

Thank you.
