Hi AV Williams,

It sounds like you've done some troubleshooting already, but let's go through a few steps to see if we can pinpoint the issues with your drives.

• Device Manager:
  • Right-click on the NVMe drive in Device Manager under 'Other Devices.'
  • Choose "Update driver" and then select "Search automatically for updated driver software."
  • If that doesn't work, try uninstalling the device from Device Manager, restart your computer, and let Windows automatically reinstall the drivers.
  • Similarly, go to the Samsung website and check for any specific drivers for your USB flash drive and T7 SSD. Download and install them.
• Rescan Disks in Disk Management:
  • Press Windows key + R, type diskmgmt.msc, and press Enter.
  • In Disk Management, click on Action from the toolbar and select Rescan Disks.
  • If the drive appears after rescanning but is not initialized, right-click on the drive and select Initialize Disk.
  • If it needs formatting, right-click on the unallocated space and choose to format it.

If these steps do not resolve the issue, it might be helpful to provide screenshots of your Disk Management window and the Other Devices section in Device Manager. This could offer more clues as to what the issue might be. Remember to avoid sharing any personal information in the screenshots.

After trying these steps, if the issues persist, it might be worth checking the event logs for any error messages related to these devices. Additionally, testing the drives on another computer can help determine if the issue is specific to your system.

Based on another machine being able to read from it fine, it sounds to me like it is most likely set to dynamic and/or a drive letter is simply not being assigned.

Click Start and right click on Computer and click Manage. On the Computer Management Window, go to Disk Management.

From here, you should be able to see a row/line in the bottom section of the page that shows your drive. Simply right click on the volume and select Change Drive Letter and Paths

On the dialog that comes up, select Add, and the drive you want.

If you can't get this far/If it says Dynamic on the left (where it shows basic in my screenshot), simply right click and chose initalise, however if this is the case, Disk Management would have said that a dynamic disk was detected when you first opened it.

Just to note: There is also a licensing restriction on dynamic disks that I just can't remember off by heart or from doing a quick Google. I believe it was where the home/basic editions couldn't read them... but, I have a feeling that was just with Windows XP.

Hi Raymund,

I am Dave, I will help you with this.

1

Right click your Start Button and open Disk Management, is the USB drive showing in the bottom pane of Disk Management?

2

If the drive s not showing in Disk Management, is that a USB flash drive or a USB hard drive?

Connect that USB drive up to another PC, does it work on that PC?

How can I make the USB stick work again?

You can't.

If no computer can "see" it, you can't use your computer to fix it.

If you had time, skills and resources, you might be able to disassemble it, identify the faults and repair or replace the faulty components. This would probably cost more than purchasing a hatfull of new USB sticks.

Update: the following advice seems to have been helpful for some people

Assuming that the drive has been properly partitioned and formatted, then this USB drive probably still needs to be enumerated for this computer. Open Control Panel. Go through Administrative Tools to Computer Management. Under Storage, click on Disk Management. Locate the USB drive and it probably needs to have a drive letter assigned to it. Do so (Right click and change drive letter - make sure it's not in use at time). Should take care of the problem.

Obviously this is only useful on those occasions when the device does show up in Disk Management (you said it sometimes did).
