Hi Grim,
Please answer these questions in order to understand the issue better.
- Did you try connecting the USB device on another computer and check if it works?
- When you USB scan and repair did you get any error message, when it failed?
This could happen due to the default behavior of Windows when you may have same drive assigned to a network drive or other hardware drive and removable pen drives tries to occupy the drive as drive letter.
In order to resolve the issue, use the following methods given below:
Method 1: Insert the removable disk in the removable drive before you start your computer. But in this case, make sure that the first boot device in BIOS is not USB drive, else computer may not boot at all.
Follow these steps:
- Log in as Administrator account in windows or any other account with administrative privileges.
- Press Windows key + X and click Disk Management
- Right click on your removable drive partition and select Change Drive Letter and Paths under Disk Management ( you can find your drive easily through size )
- Change the drive letter some other drive letter like X: or Z: which is not reserved by some other drive on windows.
Method 2: Run the Hardware and Devices troubleshooter refer to section “Run the Hardware and Devices troubleshooter” from this link:
