Hi all, I'ts my first post here.
I have an alternative to write the image into the CF, I used it to restore RAW image files (dd output) to USB and CF without problems. Check
It's small console tool (includes GUI frontend, but in German); run "PhysGUI" as admin on Vista or 7, right click on USB/CF drive, "Image laden"->"Öffnen" and select img file. Check "Remove 2Gb restriction if dest is greater than this, and press on OK twice.
Help to remove partitions on USB/CF (source: same link as avobe):
If you are unable to delete all the partitions with the Disk Management utility, try the following procedure:
Open a command window as admin ("cmd")
Type "diskpart" and hit enter.
Type "list disk" and hit enter to find out the number of your drive.
Type "select disk X" (where you replace X with the number of your drive) and hit enter.
Type "clean" and hit enter.
Hope this helps.
