So I am getting ready to a HDD to SSD swap on my Lenovo T520 (Win 7 Pro), and thought I'd make some recovery discs before I do that, as a precaution. I have Macrium Reflect Free version, which can make a set of recovery discs. But the laptop also has Lenovo's own built-in software that can create a set of OEM Lenovo recovery discs. I am wondering if one would have an advantage over the other - and trying to decide which resource I should use to make the discs... Any suggestions on which one I should use? (pls. state why, if possible). Thanks in advance. Also: one uses DVD-R discs for this purpose, correct?
