No, it is not an active system drive. By chance this drive had its
partition table blown away. Win2k is not even assigning it a drive
letter.
Also, if you look at the dd output

You see that the failure was on the write, not on the read.
I have over 50 GB free even with that file in place, so I'm definately
not short of space.
Also, I believe NTFS for Win2k has a 2 TB filesize max., so that should
not be a problem.
