We are using S2D Cluster to host our VMs.
On one of our VM we have done the following steps, which produced data loss:
1. The VM has 3 VHD (Drive C, E, G) attached on it
2. We created Hyper V production checkpoint.
3. We shut down the vm and detached 2 drives (E and G).
4. We deleted the Checkpoint of this VM and it has deleted the .vhdx files of the detached drives (E, G).
Now, we have only the .avhdx files of this dirives - not usable!
We tried it on Server 2016 and on Server 2019, the same behaviour.
