Hello
Thank you for your question and reaching out.
I can understand you are facing issue with VM disk files.
As there was power issue I will suggest you first Power-cycle HyperV host to see that if the issue resolve by itself after clean boot.
If issue still peristst with your VM then try below method to resolve the issue.
- Please take backup of current .vhdx file
2 Open that .vhdx file and mount into Hyper-V host and check the drive letter assigned from Disk management. - Repair that .vhdx file system by below command
chkdsk /f /r D:\ - Create a Test VM and attached .vhdx on IDE contoller and click on Inspect button to repiar the vhdx.
