I have used this software once to create a backup of the windows partition of a netbook, which I had to return for repair. Since I just got my money back, I needed to decide between the same model (which was even more expensive than before, as I remember correctly) or a newer and better one. So I have chosen to buy the newer one. Although I did not know if my backed up Windows would work smoothly or even boot on this completely different system, I still wanted to recover the partition to copy the interesting files manually. However, the new netbook came with Recovery Solution 5 and did not recognize my backup files. After some unsuccessful attempts, including trying to install SRS4 in a virtual machine (Admin Tool did not complete installing recovery environment, which may depend on special Samsung system functions), I created a backup with SRS5 and compared the files with my old backup.
