I'm trying to convert a fully patched, Windows Server2008 R2 system disk into a VHD by using disk2vhd from Microsoft Sysinternals.
Every time, the conversion fails with error during copy. The error could not be performed due to an I/O error
, regardless of whether I sue the vhd
or vhdx
format, or whetehr I use the Volume Shadow Copy option.
I am a local administrator, running disk2vhd as administrator and have disabled the anti-virus on the server, but it makes no difference.
I see this event in the eventlog around the same time as the error, so I suspect they're related.
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. This is often caused by incorrect security settings in either the writer or requestor process.
Operation: Gathering Writer Data
Context: Writer Class Id: {GUID} Writer Name: System Writer
Writer Instance ID: {GUID}
What's the problem here, and why can't I get this disk converted?
