database disk image is malformed

[Gael Arnaud]

Thank you Ryan, 

I’ve been through previous tickets and so far didn't find any other way to do so, but I just wanted to get this confirmed by people who understand better than I do. 
Thanks again for your answer

Or, if you are running in a virtual machine and the VM crashed or was turned off unexpectedly, it could indicate that the VM does not properly guarantee that writes to the virtual disk are propagated to the physical disk immediately.
