okay, I googled this error before posting and found some bug reports from 2009 etc but no answer to whether I can fix it.

Failed to open the hard drive
(drive name and location here)
Could not get the storage format of the medium

Result Code:
Component: Medium
Interface: IMedium {1d578f43-5ef1-4415-b556-7592d3ccdc8f}
Callee: IVirtualBox {3f36e024-7fed-4f20-a02c-9158a82b44e6}

this .vpi had been working just fine then poof, (technical term)

any hope to fix it?

I'm getting this while trying to backup my VM with the following command:
Code: Select all   Expand viewCollapse view
VBoxManage clonevdi "$FILE" "$TARGET" --existing

The full error message is:

The error would indicate that the file system that hosts the VDI file is unknown to VB. E.g. it's an btrfs partition and VB does not have full support for that to host files on. Did you change anything on the volumes you have mounted?
