I've ran into a problem with XCode where it keeps crashing on startup, and I thought of reinstalling macOS Sierra but I'm actually nervous that it might screw things up. I've seen videos on Youtube but they format the drive then reinstall. Should I reinstall macOS Sierra only without formatting my drive?

It is a bit extreme to delete your OS and reinstall just because Xcode isn't starting up. Have you booted to your Recovery HD
and run Disk Utility> First Aid. Or you could install the Combo update, https://support.apple.com/kb/DL1931?viewlocale=en_US&locale=en_US install it over what you have got it'll reset some system files and caches.
Or you could delete Xcode and then re-download and install it.
Reinstalling an OS should be a last resort.
I restarted into recovery mode and was only able to first aid the APPLE SSD SM0256G Media HD (macintosh HD didn't let me first aid), do I also first aid the OSX Drive as well that also appears?
Why couldn't you run First Aid on your Macintosh HD, can you show what you see in Disk Utility.
You may have to post a photo taken with your camera phone or camera.
You don't need to do the OSX Drive, but it won't hurt anything by doing it.
You your Macintosh HD is not mounted, therefore mount it, select/ highlight it and click on the Mount button.
Hello xteal, try to create another user account first.
Already tried it-- moved xcode to applications folder and still crashed on another user. Plus the issue is a missing file.
Forgot to add on one more thing. Since it's usually a one time thing to upgrade, can I just copy my macintosh HD to my 1TB hard drive? Or should I format my drive just to do time machine
Do I need to format a disk drive before reinstalling my OS?
