so long story short, my newly purchased external SSD got corrupted a day after formatting it and wouldn't erase. I read somewhere on this site that if I tried to format it to Mac OS Extended (Journaled, Encrypted) that I could then erase the disk over again and format it correctly. It has now been "Switching to Core Storage" for well over an hour and I fear it's going to keep doing this throughout the night. Now, if this is normal, I will simply let the process happen, even if it means the mac will have to stay on while I sleep, but I'm not particularly interested in keeping this process running if it's not working properly. Any help as soon as possible would be greatly appreciated!
