Hi guys, I'm new here. I have a late 2011 MacBook Pro 13-inch. The original HDD on this system started failing, so I replaced it with an SDD Samsung 860 EVO of 500BG. I also updated the RAM. After replacing the original hard drive with a solid state drive, my MacBook Pro ran extremely slow. Just to hit an icon like the apple button to check the system, took a minute or two with a search color wheel. So I decided to just reformat the SDD and redo everything again. I also want to mention that my Time Machine wasn't reading my SDD. I don't really care about erasing everything on here, because prior to that I backed everything up on an external drive. I just want a clean solid macOS installed with absolutely nothing. However, when I try to do that and reformat my internal disk, it seems like I still have volumes on my partition, and it shows up as full. I did erase the Macintosh HD before that, because my Samsung SDD internal drive wasn't showing up on my disk utilities. When I erased my macintosh HD, I was now able to see my internal SDD. I'm still having an issue with the partitions and not being able to erase the volumes on the SDD. I don't know a whole lot about the partitions, especially on a Mac, but I can't even load a clean install of High Sierra macOS, because I keep getting an error message that says, "The recovery server could not be contacted." I did set the correct date on terminal many times, and even to match apples time servers. I made sure I had internet and WiFi was on, I also tried changing the date on terminal to when High Sierra came out, but I still keep getting the same message. Not to mention I can't erase the volume on my SDD. Does anyone know how I can fix this? I will provide screenshots on here as an example(sorry if they are blurry, but I couldn't take screenshots from the actual Mac itself, so I had to use my phone). Any information regarding this would be helpful.
