Only one additional remark so far: The problem seems to be connected
to Windows XP (tested SP 3 so far). On Vista the same task with the
same hard drive runs smoothly, while going back to an XP machine shows
the same slow behaviour again.

Hi Andreas,
I was told that kind of experience (version 2.6.9) a couple of weeks
ago. When I restart the sync mission, it's OK.
I don't know why also. Do u have any progress about this ?

Ok, thanks for the inputs. The problem continues, though. I'm using
the current cwrsync version now (which includes rsync 3.0.5). The
detailed output shows that the receiving of the file names works
perfectly, but when the generator starts things are getting very
slow.
It somhow takes unacceptabely long for these tasks:
[generator] make_file(x/y.pdf,*,2)
The files in question are sometimes quite large (200-300MB). I also
tried to use the parameter "--size-only" but that did not help
either.
However: If I cancel the job and run it a second time, these
"make_file"-tasks are executed in a normal fast way for the files
that
have already been checked until it reaches the files that were not
covered during the first (incomplete) run. And: When I attach the
drive to a darwin pc and sync it there, then go back to the windows
machine and do a sync again, the slow checks begin anew.
Can you give more hints based on these infos?

As I can't predict which OS they will be used with they are
formatted
with fat32. If I use them with either Linux (ubuntu) or OS X rsync
works without problems. However, when I try the syncing with the hd
attached to a windows pc the rsync process (using cygwin) will take
close to 40 minutes only check what needs to be updated. Does
anybody
know what could be the cause for this strange behaviour? Is it
something with permissions (parameters I used for initial
creation of
the copy were "-rtluvz --modify-window=1")? Or are there
compatibility
issues with rsync/cygwin?
Cygwin might just be slow, or there might genuinely be something
strange
going on. Increase the verbosity to -vvv to find out more about
what is
taking so long. Also, you may wish to use rsync >= 3.0.0 on the
Windows
machine to get the speed benefit of incremental recursion, if you
aren't
already doing so.
