I have a great problem to deal : no access anymore to Ubuntu through my VirtualBox. I always have the same message

Session failed to Open

Could not open the medium '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi'.

VDI: error reading pre-header in '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_DEV_IO_ERROR).

VD: error VERR_VD_VDI_INVALID_HEADER opening image file '/Users/me/VirtualBox VMs/Ubuntu/Ubuntu.vdi' (VERR_VD_VDI_INVALID_HEADER).

Code d'erreur : NS_ERROR_FAILURE (0x80004005) Composant : Medium Interface : IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd}

I tried to follow this post explaining how to mount manually the vdi file. But I can't open my 6go sized file nor with HexFiend, nor with 0exED... And if I did, how do I find the pre-header ?
