So with Mojave around the corner, I'm wanting to wipe out my Mac and do a fresh install (it's never had one, and has been running since 2015). Problem is that I use my external hard drive for my Wii U titles, and I have nearly a TB of data that needs to be backed up from my Mac. Since Nintendo has finally decided to care about CDN downloads, I'm wondering if I can image the drive using dd, then re-image it after I'm done. Has anyone attempted this?
