Comment # 2 on bug 1122723 from Ed Damvelt

/C: is only Windows 7, no data at all. All user temp data, Win and Suse, point
to /C:/Tmp.
All userdata, Win and Suse, point to /D:, no exception and not things all over
the place.

10.5GiB of 24.6GiB free on /C:, 35.6GiB of 403.8GiB free on /D:, same values in
Opensuse and in Windows.

The machine is a HP Pavilion with an Intel Duo 3750 at 2.0GHz, 4GiB memory and
490GiB HD. There are two DELL PCs with Intel 4-cores at 3GHz that have the same
dual system installed as this laptop, but I risk not playing around on them as
they are directly running a few client's microprocessor systems. I don't
remember whether I ran into this on those ever before.

Ad 2) from my first comment:
I played around a bit here and tried to find a possible causal connection, but
so far no indication.
If in / I run Properties for /C: I get the right device usage but with size of
6B and 0 files. However, sometimes in the same session nothing at all is
indicated there for size and when I then click Calculate, I get a size
indication of 128TiB (I wish) and a few million files.   

If in / I run Properties on /D: I sometimes get the device usage figures from
/C: (10.5 and 24.6); when I then open /D:, it only shows me two or three text
files. If Properties starts with calculating, it gives me the real device
usage, and opening /D: then indeed gives me also the real content. 

With all this, there is no difference whether this is done in the left or the
right window of Dolphin.
