I have just done some testing as promised with the hidden trash folder on my
ntfs drive and found that both df -h and du -hs /* did not report the changes
in file sizes on the /media volume until I manually deleted the files from it
(therefore it would appear that both commands respond to changes in hidden
files at least when files are deleted from them). However they were
consistently 0.9 Gb adrift in the sizes they were reporting despite the fact
that the folder I was using for testing was a little under 300 Mb.
I am going to do some more testing as this happens to have some bearing on my
line of work. I will post back if I come up with anything
significant/relevant/interesting.
If anyone out there can provide a full explanation of why/how this occurs I
would be very interested. I am sad enough that I find this kind of thing
fascinating :-)
I hope you resolve your issue soon.

du counts disk space used at a block level and not accurately counted
bytes. There is a -b parameter which gives the more realistic apparent
size of files.
Also du doesn't by default count hidden files.
You're also counting /proc and /dev which aren't really directories
with
files in on disk.
Cheers,
Al.
