Sorry, I have to delete some quoted text otherwise this reply will be 
unreadable.

The figure highlighted is the total number of 1K blocks in the 
filesystem. The total has not changed, but the used and available 
figures have, as would be expected.

Perhaps I'm misreading the ascii-arrows; the change in filesystem usage 
is 945796 K, which is smaller than the 2GB you reported. The further 
examples given make the same point.

Please check whether the original xc51small.hda is a sparse file, which 
would explain the difference between size as reported by ls and du, and 
space occupied on disk as reported by du and df.


Cheers,
