Hey guys, I installed a new ssd, followed a tutorial on lifehacker website about installing an ssd without reinstalling windows , and I was on a step that told me to format my hdd but windows said I couldn't. Why couldn't I? All I did was backup all my hdd data on an external drive and also clone my hdd to my ssd. I didn't have multiple partitions(just in case that's a relevant fact). What do I do at this point? When I tried to boot from my ssd it was insanely slow. Back to my question: how do I know my ssd is working properly? Thanks
