Disk Utility Restore causes “Could not validate resource – Invalid Argument”

disk-utilityosx-snow-leopardrestore

I have a problem with Disk Utility on Mac OS X 10.6. I have an image of Windows that I would like to use as a bootable volume on a pen drive or external hard drive. The thing is:

  1. When I try to restore the volume from the image I get an error:

    "Restore Failure: Could not validate resource – Invalid Argument"

  2. I read some information about that error on the Internet. I converted the image into .iso (Mac OS Extended/ISO (Joliet) Hybrid Image) format and then got this error:

    "Restore Failure: Could not find any scan information. The source image needs to be imagescanned before it can be restored."

  3. When I try to scan the image for Restore, I get the first message.

I really read a lot of information about this topic on the Internet, but I haven't found the solution.

I tried both ISO and DMG formats; I don't know which is best.

I would suggest WinClone, which worked well for me once when I needed to backup a Bootcamp partition. The developer's website is here: http://www.twocanoes.com/winclone/

You can try an older, shareware demo here: http://mac.softpedia.com/progDownload/Winclone-Download-27227.html The third Download Location labeled as "Softpedia Secure Download (RO) [DMG]" appears to be still available.
