For MacOS (where realistically you'd be doing this for an external drive as I believe they don't show you much or anything at all on modern internal drives) you can get a free trial of DriveDX. There are probably other programs you can use for free, but if you only need to do it once, just get that because it does a really good job of letting you know what's up. Just visualizes things in an easily newbie-understandable way.
