Format SD Card after eMMC install


#1

Hello guys, I configured my SD card for an eMMC install. It all went fine, but now I want to repurpose my SD card. It’s currently partitioned in 9 different sections (as seen on my Mac) and there’s no way I can format it. I tried plugging it into my Windows machine with similar results. Any ideas? Thanks.

I use Disk Utility on Mac to reformat the disk.

This seems to document the process:

Thanks barry, but unfortunately this time it doesn’t seem to be that easy. Here are some screenshots:

There’s a free Windows util called “SD Card Formatter” that I used to fix it, as per a Reddit suggestion.
