Post Update Problems

[Gesù Cristo]

Hi to all. I've just uptated addictions and Vbox to 5.0.16 version but since then i'm unable to access to my vhds cause i get ERR_SHARING_VIOLATION repairing corrupted image file or something similar. I tried to go back 5.0.14 but still i can't access to my disks. What can i do? I have to toss all of them 'cause of the update?

Sharing violation means something else has the files open. You need to find out what that is, or if you don't know how, at least reboot the host.

already did it but still not works, it seems i've lost everything. While trying to mount an existing disk it also shows this message:

Upgrading or even uninstalling VirtualBox does not touch any virtual disks, VM settings, or anything like that. So something else must have. You can always look at the 'VirtualBox VMs' directory in your home directory what is or isn't there.

When you say " i get ERR_SHARING_VIOLATION repairing corrupted image file or something similar" I don't suppose you can provide the exact error message?

The fact is I tried several attempts to fix the problems, but i didn't get always the same error. Btw actually, after deleting and reinstalling vbox 5.0.16 plus expansion pack when i mount former vhds it says me that:

Could not open the medium 'C:\Users\Roberto\VirtualBox VMs\MADRE COMPLETA + Framework - Copia\MADRE COMPLETA\DIO.vhd'.
VD: error VERR_VD_IMAGE_CORRUPTED opening image file 'C:\Users\Roberto\VirtualBox VMs\MADRE COMPLETA + Framework - Copia\MADRE COMPLETA\DIO.vhd' (VERR_VD_IMAGE_CORRUPTED).

Analogue situation already occurred months ago but that time i simply tossed all my disks and started again. Would like to understand why, i don't want to chose if uptating vbox or restarting all work again.

I didn't know Jesus ever had errors!

Image Corrupted means that Virtualbox for some reason can't make sense of what's in the file. Being that it's a VHD, the possibility is rather good the image is dead. VHD has a serious design flaw where the information that describes the contents of the file is actually at the end of the file, instead of at the beginning, like VDI and others have. When the VHD file gets bigger, this information needs to be moved and re-written somewhere else on the disk. If this information fails to get written due to a computer glitch, the vhd is dead. Microsoft may have a way to resurrect the file, but Virtualbox doesn't.

Your only hope now is to restore from a backup.
