VDS Basic Provider




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 can happen when:

  • 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.

User Action
None required. This event can be safely ignored.

  • I have no guest operating system, Hyper-V or otherwise, just Win7/64 and no SCSI controller. This error occurs when Win7 can no longer find a connected disk drive. Hardly something that can be safely ignored!

  • Same as Bugfinder General, no VMs Win 7 x64 and no SCSI. It is also not clear which disk this is referring to, so it is hard to even try and troubleshot.

  • Ditto as Bugfinder and bigbilly I have a SSD with my OS and all my storage is handed to a WD 1TB drive, I hardley accept safely ignore.

  • With event data "1@01010003", the disk management is crashing (i.e. waiting forever to load the infomation for the disk configuration), sure, this can be ignored, but the disk management crashes anyway... A solution for this would be really helpful.

  • Also the same like Bugfinder General, bigbillyt and Lunker 1.

    Win 7 x64 no SCSI no VM.
