VERR_VD_VMDK_INVALID_HEADER in virtualbox after hard reset

Question

I had to hard reset my notebook after my system (Ubuntu gnome 15.04) freezes. Now I'm not able to resume the vagrant and if I try to load it on virtualbox I receive this message:

Could not open the medium '/home/stsmuniz/VirtualBox VMs/vagrant_default_1441759013197_1623/box-disk1.vmdk'.
VMDK: inconsistency between grain table and backup grain table in '/home/stsmuniz/VirtualBox VMs/vagrant_default_1441759013197_1623/box-disk1.vmdk' (VERR_VD_VMDK_INVALID_HEADER).
VD: error VERR_VD_VMDK_INVALID_HEADER opening image file '/home/stsmuniz/VirtualBox VMs/vagrant_default_1441759013197_1623/box-disk1.vmdk' (VERR_VD_VMDK_INVALID_HEADER).

Can anybody help me on solving this?

Solution

This is a problem with a corrupt vmdk disk. It is discussed briefly on the Whonix troubleshooting page.

To fix it, the idea is to convert the vmdk disk into a vdi disk, unmount the old vmdk disk from the VM and attach in its stead the newly minted vdi disk.

Tools to do that are discussed here and here.

I did the steps shown here and after converting the box to VDI it worked. Thank you, buddy.
