How do I format a bare hard drive to macOS Sierra?
Hi, I'm brand new to working with hardware so bare with me.
Recently during startup, my computer would throw a kernel panic error, and shut down. I spent a large amount of time trying to understand just what was going on, and it came down to either my hard drive or its cable being broken. It looked like it was my hard drive so I decided to buy a hard drive and replace it using the guide on this website.
So here's the problem: The computer starts up at least, and doesn't throw any kernel panic error. Instead, my computer does not recognize my internal hard drive at all. I'm assuming it's because my new hard drive probably came unformatted, and therefore my computer doesn't recognize it. So, how do I format my internal hard drive so that it is compatible with macOS? I've heard of a multitude of options, such as using a firewire or a thunderbolt cable, or using a usb with a macOS partition on it, or restoring files directly from an external hard drive, but which of these actually work? The only item I have of the above three options is an external hard drive which holds a backup of my computer's files. Would I be able to somehow format my new unrecognized hard drive through my external hard drive files? If my hard drive is not recognized in Disk Utility at all, would it still work? If not, what should I do in order to make my computer recognize my unformatted hard drive, how can I reformat it, so that I can reinstall macOS Sierra on it and restore from my external backup?
Is this a good question?
