What is event ID 158?
According to Microsoft, the Event ID 158 that pops up in the Windows event logs indicates that two or more physical disk devices in Windows 11 or 10 are assigned identical disk GUIDs. Event ID 158 is also known as Disk Signature Collision.
GUID stands for Globally Unique Identifier and is a 128-bit integer number to identify resources. It is a common term that is used by developers working with Microsoft technologies. Others use UUID which stands for Universally Unique Identifier.
Notably, Event ID 158 does not have any functionality or performance impact on Windows PCs. It just warns you that two or more disk devices are sharing identical disk GUIDs.
What are the possible causes of Event ID 158?
This problem can be caused by any of the below-mentioned reasons:
- Microsoft Multipath I/O (MPIO) isn’t enabled – In this case, multiple paths will be assigned to the physical disk because the device is exposed to the system by all paths so Disk Identifiers, Device Serial Number, Vendor ID, Product ID, etc. are exposed to multiple times.
- Virtual Hard Disk is duplicated to create Virtual Machines – If the user has performed copy and paste operations to create Virtual Hard Disk (VHDs) to create more Virtual Machines (VMs) then the same Device Serial Number, Vendor ID, Disk Identifiers, Product ID, etc. are exposed to multiple times.
Let us now take a look at the most effective solutions that will help you resolve the Event ID 158 issues on your Windows PC.
