syncing local on Win9x between different partitions

[Peter Reif]

I am using rsync for Win9x with the cygwin1.dll.
I want to sync two partitions locally. If I type

  rsync \dir1\ d:\dir2\

rsync tries to make a rsh-connection to host "d".
I think one solution is to mount the D partition with cygwin.
Is there a simpler way?
