Consider the following scenario:
  • You have a Hyper-V guest operating system that is running Windows Server 2008 R2 or Windows 7.
  • The guest operating system has a disk that is connected to a SCSI controller.
In this scenario, the following event is logged in the System log:

Log Name: System
Source: VDS Basic Provider
Date: date time
Event ID: 1
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: computer name
Description: Unexpected failure. Error code: 490@01010004


The Virtual Disk Service (VDS) looks for the Location paths property of the controller. The value of this property is the path location of the disk. However, a virtual controller does not have this property.


This event can be safely ignored.
