Well, "Anonymous" was right, I just didn't read your mail further after I saw the usage of \\\\.\\physicaldrive1, I apologize.
I never heard of such a 1TB border which would result in problems. However, due to the lack of such a big drive, I can't debug that, obviously.

So it's a Windows function which chokes. Could you please run the above dd under strace and send the strace output to this list? Perhaps that helps to track this down.
