I need to extract data from a disk of NAS HS box (remember that NAS has a Linux kernel, while my computer is Windows). I was afraid of having to install Linux on my computer to my records. Well no! This station sees partitions (although they are not all accessible, Linux requires) and one containing the data was completely accessible. I was able to save them before using the disc with a new NAS box (which usually generates a formatted disk). I have not used cloning.
