Сначала я размонтировал:
$ diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful
Затем я стираю диск и форматирую его в FAT32
$ diskutil eraseDisk FAT32 NEW_NAME /dev/disk2
Started erase on disk2
Unmounting disk
Creating the partition map
Error: -69877: Couldn't open device
Как я могу стереть диск и отформатировать его в FAT32 без использования сторонних приложений?
