How to fix corrupted VHDX files?

There are a lot of questions out there about how to fix corrupted VHDX files. Here I am going discuss the ways to recover files from corrupt VHDX file(Virtual Machine).

Before going into more details about how to fix corrupted VHDX file. Let me introduce you what is VHDX(as a lot of the crowd know) and how VHDX file gets corrupted.

VHDX file is a Hyper-V Virtual Hard Disk file developed by Microsoft used for heavy data storage, found on Window server 2012. After VHD format, VHDX came into to the tech world for handling huge data storage on Hyper-V Server like Window Server 2012 R2. There was storage challenge for virtual machines when larger workload ends up as VHD. This was overcome after the discovery of VHDX file format.

Though it overcomes the storage workload but does prone to corruption. Besides, Hyper-V has auto-repair features to repair VHDX files if it detects a corruption in a VHD/VHDX file. But this is not always a solution. A virtual hard disk file is made up of a hard drive footer that contains information about the disk, such as size and geometry, and data blocks. If the disk is dynamic, there is a dynamic virtual hard disk header. And if the footer of VHDX file gets corrupted for any reasons. An unexpected error occurs: The file or directory is corrupted and unreadable. (0x80070570)."

To overcome such error or to fix corrupted VHDX file, look out the method that you may need to perform to recover VHDX(extract data from VHDX).

1. If data in the VHDX is corrupt, then run disk repair tools within the virtual machine (such as chk disk) and recover data.

2. If you fail, you may go for another tool that SysInfoTool VHDX Recovery. However, ensuring you have a good recovery strategy in place is the best option.
