Hi Saltgrass;
Thanks for the great tip! Got the latest Ubuntu distro, but couldn't get it work to generate a USB bootable pendrive. (Graphics) Went back to an older Ubuntu 9.0.4 LiveCD version and after carefully moving (cut/paste) 1 directory and checking it under Win7 I was able to move that 1,3TB directory without any risk.
Saves me a lot of time in order to move it to an other disk and move it back again to it's original location.
Again; thanks for the tip.
Kind regards,
Hans
