1) open a console
2) type “su” <cr> to get superuser, and enter the password <cr> when requested. Then type cd /mnt <cr>
3) type “mkdir win” to create the directory “win”.
Note: in your case you need directories for hda1-(win1), hda5-(win5) & hda6-(win6)
4) still as superuser, type “kate”
5) open /etc/fstab in kate
6 ) at the end of the file create a new line that looks like the following:
/dev/hda1 /mnt/win vfat defaults,exec,umask=000 0 0
(Note that hda1 is assuming that Windows is located on the first partition of the first hard drive on the first ide controller on your system)
7) save the file and exit
9) make a right click on your desktop, and click on “create new”-->”hard disk ...”
10)move to “Device” and select “/dev/hda1 (/mnt/win)”. Make sure that the button “read only” is UNchecked. Click on the “o.k.” button.
(note: you can of course also rename the file to “windows”

You should now be able to mount your windows hard disk (also writable!) by double-clicking on the Icon you created in step 9 and 11) Hope this helps, but if you've got any problems or don't understand something, please feel free to post again!
Enjoy!
