Hello Xen, Nils and Everybody.
Thanks for your advises - they worked out well for me.
I have carried out the following commands:
(For getting into the root mode.)
chown -R bas.bas /media/bas/Thuis
(One of the external HD's.)
chown -R bas.bas /media/bas/Thuishaven
(Another external HD)
chown -R bas.bas /home/bas/Desktop
(Also that folder was owned by root.)
However it may be - the above commands worked like a charm. It took less
then 5 minutes per command.
