Rashkae,
Thanks for your speedy reply.
I did what you asked but the only "error" I got was:
joep at Laguna-new:~/Utube/utubeqt$ sudo gparted
======================
libparted : 2.2
======================
Unable to satisfy all constraints on the partition

and dmesg gave no error. It doen't look like an error but more that 
something in the disk layout is not known by gparted.
An external disk (dev/sdb), also of 1 Tb. is seen without a problem.
Both disks as Samsung and I have no problem whatsoever with them.
