I want to transfer the 2,5'' SSHD from my old laptop(Lenovo G505s) into a free slot on my new laptop(hp omen 15-ax201no) which only has a 256GB M.2 SSD. The SSHD was the only disk on the old laptop and has OS windows 10. My new laptop also has windows 10. Can i just plug it in, or should i remove the OS. And any tips to clean a harddisk completely?
