Corrupt VMDK

[UptimeDEMO]

Good Morning - a few months ago we had a power outage at work and my host machine ended up shutting off and my main Windows 10 VM no longer boots. I tried everything, to no avail. From my searching, it looks like someone here can help me, or at least point me in the right direction to be able to manually repair the VMDK files so I can get this machine to boot. I believe I have included the information that would be needed to help me!

yes I know I should have had a backup...

With the huge number of errors in the "Virtual Disk-cl2-s032.vmdk" file's metadata, I'm afraid that repairing this file will be close to impossible. It's like a puzzle with thousands of similar pieces.

Anyway what should work to at least be able to access the virtual disk again, and even power on the VM, is to replace the corrupted file with one that just contains metadata.

The steps you may try are:

1. optional but recommended, backup the VM's complete folder/files
2. rename "Virtual Disk-cl2-s032.vmdk" to e.g. "Virtual Disk-cl2-s032.vmdk.org"
3. replace "Virtual Disk-cl2-s032.vmdk" with a copy of "Virtual Disk-cl2-s038.vmdk"
4. create a snapshot! This will prevent the current .vmdk files from being modified, so you can revert to the current state in case you need to.

Unless another .vmdk file has corrupted metadata too, you should now be able to use the virtual disk again, and power on the VM to be able to access, and backup important data. Note that the ~8GB which were stored in the corrupted file are unfortunately gone, which not only means that some data is lost, but also that there will be some file system corruption in the guest OS.

Excellent, that worked! Thank you. I was able to get into my VM and pull a backup of the data I needed.

You're the best!

If you need to recover VMDK files that have been corrupted due to events such as VMware tools crash, power failure, hard disk crash, virus attack, and more, consider using the Cigati VMDK Recovery Tool. It is a leading utility designed to efficiently repair corrupt VMDK files on any version of the VMware virtual machine.
