I got an SSD recently for my computer. After cloning everything over to it I was told to shut down my computer and remove the HDD that I was previously using . I did so and everything seemed to work fine, all of my stuff transferred and the SSD was now recognized as disk C:. I then went to reinstall my HDD for extra space. Upon starting up my computer I opened task manager to make sure that my SSD was still disk C: it was but then I noticed that the HDD was now recognized as disk D: and E:. I opened up my file explorer and saw that there was a local disk C:, local disk E:, and a System Reserved D:. I then opened up disk management and saw that my HDD was being recognized as disk E: and that there were two system reserved volumes. One was labeled as D: and the other had no label like it did before installing my new SSD. Is it okay to delete the system reserved D: volume and is it alright to format my old HDD to clear it duplicate files.
