An error event for Event ID 158 is logged. The event indicates that two or more disk devices are assigned identical disk GUIDs.


The above event message has no functionality or performance impact on the client systems. This event provides a warning that multiple disks on the system shared the same identification information (like serial number, page 83 IDs, and so on.)


This problem may be caused by any one of several different situations. The two most common situations are the following ones:

  • Multiple paths to the same physical disk device are available. But Microsoft Multipath I/O (MPIO) isn't enabled. In this situation, the device is exposed to the system by all paths that are available. It causes the same device ID data (such as Device Serial Number, Vendor ID, Product ID, and so on) to be exposed multiple times.
  • If Virtual Hard Disks (VHD) are duplicated by using a copy-and-paste operation to create more virtual machines (VMs), none of the internal data structures are changed. So, the VMs have the same disk GUIDs and the same ID information (such as Device Serial Number, Vendor ID, Product ID, and so on).


To resolve this problem, if multiple paths are available to the physical disk devices, enable MPIO. If MPIO is enabled, the system can claim the drives and expose only one instance of each disk device when the computer is restarted.

More Information

For more information about how to enable MPIO, see Installing and Configuring MPIO.

If multiple VHDs are identified as duplicates, use the ResetDiskIdentifier parameter of the Set-VHD Windows PowerShell cmdlet. For more information about the Set-VHD cmdlet, see Set-VHD.
