Hello,
after properly shutting down a Guest VM running Windows Server 2008 as O.S., I've found that one of its .vdi disks has size equal to 0 bytes and VirtualBox cannot start the VM again. Below I attach the associated "VBox.log.3". I've found that in my Host there are other two disks with size equal to 0 bytes. Failing .vdi virtual disks were stored in a NTFS partition of the physical disk and Host's O.S. is Ubuntu 14.04.
What could have happened? Is it due to a failure in the Host physical disk?
Thank you,
Alfredo

Is there a log from when the guest actually worked? Also if this is not really easy to diagnose you will need to ask Ubuntu since this is their fork.

Look at the logs of the guest and if one has real data post that here as an attachment. Compress it if it is too large to post otherwise.

Is the 0 bytes genuine or just a reporting glitch due to the file being open for writing?

How reliable is the NTFS driver on Linux? ISTR it used to treat the partition as read only if NTFS was used.

Not all that sure that NTFS ever had an issue in Linux with the exception of it being slower than native formats. One exception might be RAW but I have not tried that in years since there really is no need, at least in my case.
