I have a slightly different problem with the same error message.

My XP sessions began failing (probably after a couple of premature shutdowns) and gave me blackscreen startups so I deleted the current .vhd file and replaced it with a ten-day old backup (always keep a backup ).

However, this is now giving me the error message on startups:

VD: error VERR_VD_VHD_INVALID_HEADER ....(VERR_VD_VHD_INVALID_HEADER)

I can't use the Discard option because it's not highlighted.

I'll explore two options, repeating the copy of the backup, or creating a new XP by importing the backup, but any other options or suggestions will be helpful.

I have the same problem - I had to turn my PC off because it didn't respond anymore. Now I cannot open the vhd-file any more. Is there any way to fix the corrupt vhd-header?
Thank you

I'd like to see some form of recovery facility too.

My only solution to-dater was to recreate the VHD from source. Fortunately, in anticipation, I kept a copy of the original source project file (a Windows Virtual Machine file) to import and revive most of my VHD file.
