Dear Intel-Otaku,
Welcome to the Microsoft Community
Thank you for reaching out with your concern about the Event ID 158 warning on your Windows 11 23H2 system. I understand this can be frustrating, especially since the provided solutions do not apply to your non-server environment.
Event ID 158 typically indicates a problem with disk identifiers, which might cause issues when multiple storage devices are connected. Since the solution you found is geared toward server environments using MPIO, we’ll try a different approach suited to your setup with external USB drives.
Here are some steps you can take to potentially resolve this issue:
- Disconnect and Reconnect External Drives:
- Safely remove all external storage devices.
- Restart your computer.
- Reconnect the devices one at a time, allowing Windows to recognize each device anew. This might help in reassigning the disk identifiers properly.
- Update USB Controller Drivers:
- Open Device Manager (you can search for it in the Start menu).
- Expand the ‘Universal Serial Bus controllers’ section.
- Right-click on each USB controller and select ‘Update driver’.
- Choose ‘Search automatically for drivers’. Windows will attempt to find and install any updated drivers available.
- Change Drive Letters:
- Open Disk Management (you can search for it in the Start menu).
- Right-click the drives (particularly the external ones) and choose ‘Change Drive Letter and Paths…’.
- Change the drive letter to something different. This can sometimes resolve conflicts that might lead to such warnings.
- Use Diskpart to Clear Disk Attributes:
- Open Command Prompt as an administrator.
- Type
diskpartand press Enter. - Type
list diskand identify your external drives by their size. - Type
select disk X(replace X with the disk number). - Type
attributes disk clear readonlyto ensure the disk isn’t set to read-only. - Be cautious with Diskpart as it is a powerful tool. Make sure you are selecting the correct disk to avoid any data loss.
If these steps do not resolve the issue, it might be useful to look into the specifics of the hardware configuration of your external drives or consider consulting with a professional to physically inspect your setup. Please let us know how it goes, and if you need further assistance, we’re here to help.
