Originally the drive looked like this (using diskutil list):

/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *8.1 GB disk4
1: DOS_FAT_32 PRUSA_MINI 8.1 GB disk4s1

I have erased it using:

diskutil eraseDisk "MS-DOS FAT32" PRUSA_MINI /dev/disk4

and now it looks like this:

/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *8.1 GB disk4
1: EFI EFI 209.7 MB disk4s1
2: Microsoft Basic Data PRUSA_MINI 7.8 GB disk4s2

How to format it as it was originally? This has to be read by a 3D printer which doesn't know a lot of filesystems.

diskutil eraseDisk "MS-DOS FAT32" PRUSA_MINI MBR /dev/disk4

or just use the Disk Utility app: FAT, Master Boot Record.

diskutil eraseDisk FAT32 PRUSA_MINI MBR disk4
should work just as well. Use diskutil list to confirm it’s still disk4.
