Starting Virtualbox guest shows VERR_SSM_LOAD_CONFIG_MISMATCH

The host machine experienced a power failure, when a guest machine was started up it failed with error message below.
Failed to open a session for the virtual machine MACHINENAME.
ahci#0: The target VM is missing a device on port 0. 
Please make sure the source and target VMs have compatible 
storage configurations [ver=6 pass=final] (VERR_SSM_LOAD_CONFIG_MISMATCH).
It seems like Virtualbox virtual machine configuration was corrupted. Looking at the virtual machine settings noticed that the virtual HD attached to the SATA port was gone.

To workaround this case, re-attached the latest snapshot to the VM. Use Virtual Media Manager to determine the correct UUID.
