If you search the web on this file name you will find many references including articles like this one http://www.kodyaz.com/content/HowtoInstallMicrosoftWindowsVistaBeta2.aspx
This error is usually connected with using the image file in a virtual drive. The usual fix cited is to burn to dvd. MS advises that a slow burn speed prevents many file copy errors. They recommend 2x or 4x. If you do not have a dvd drive this year is the year to get one. Vista is not the only software likely to ship on dvd's only going forward.
