Ok, I did a full imagebackup with the Win7 backup tool on build 7000. Now in build 7077 I am trying to access the created VHD images. Unfortunately when trying mounting the image I recieve one of two errors: 1) If image is on a Bluray disk I get the error "The requested operation could not be completed due to a file system limitation", even if I select read only. 2) If the image is on a local HDD i get the error "The file or directory is corrupted and unreadable". The same error as you get when mounting a format that Windows VDS does not recognise. At the same time I get 3 event log entries with the error "Unexpected failure. Error code: 490@01010004", this is not recognised on any MS sites that I can find. Any ideas on how I can access these images?
