I looked into this and came up short but found causes from failing drives, non-admin accounts, Norton (again), Nvidia chipsets and more.
Sorry but I can't see which one applies.
PS> A good collection of such errors and cure at http://www.pchelpforum.com/windows-vista-7/89091-volsnap-error-during-shadow-copy.html
I haven't got any restore points listed I realized a few months ago, and when I try to create one myself I get the error message saying
"The restore point could not be created for the following reason:
The specific object was not found. (ox80042308)
Please try again"
and it lies, trying again does not work lol
When I check the even viewer it has errors from both VDS and VSS. VDS says "Unexpected failure. Error code: 490@01010004"
The VDS error has occurred twice today apparently.
The VSS error has occurred once today in the event log which states
"Volume Shadow Copy Service initialization error: the control dispatcher cannot be started [0x80070427, The service process could not connect to the service controller.
There is also another error that states
"The shadow copies of volume C: were aborted because of an IO failure on volume C:."
and it's "Event14 volsnap" which has occured 4 times apparently in the last hour.
I've been looking on google for ages and have tried nearly everything I've found. I saw someone with the same problem and theirs was fixed with just a disk check, but mine wasn't.
anyway, please help me. I don't like my computer not being able to create restore points, it worries me.
