What is the most recoverable format in case of data catastrophe?

[Marinbox]

I would like to know if any of the formats that can be used to create a virtual disk is safer than another. That is to say, before a hardware failure can be recovered easier or there are more tools for the repair and recovery of information.

What format do you recommend to use?

The one that you have a backup of, the one which you've verified it can be restored at any given time.

VirtualBox knows better its native format, VDI. There are a couple of tools around that could help with a corrupted header (maybe), including mpack's CloneVDI and/or the built-in "vbox-img" which although not properly documented (not at all actually) offers a "repair" option.

$ vbox-img
Usage: vbox-img
...
   repair       --filename <filename>
                [--dry-run]
                [--format VDI|VMDK|VHD] (default: autodetect)

Thank you for answering socratis.

It has been a great help.
