How to Resolve the Issue of IO Device Error When Using Disk2vhd?

There is a known solution is using the chkdsk tool to do error checking on the hard disk first and then use Disk2vhd, we suggest you can try it first.

The chkdsk error solution did not work for us. Our solution is turning off the anti-virus software.

We installed AVG anti-virus software on our computer, it caused the error message when we used Disk2vhd tool. After we turned it off, we got the disk converting to .vhdx file successfully.
