Formatting SD card as FAT32 on Mac?
Named brand micro SD with 8 gigs on it. Trying everything to format as FAT32, on a Mac running Sierra and I get this error:
/dev/disk2s1 does not appear to be a whole disk
When running this:
$ diskutil partitionDisk /dev/disk2s1 1 MBRFormat "MS-DOS FAT32" UDOO 1024M
Any idea what's going on here?
partitionDisk
wants the entire drive as its target, because it's about to erase all partitions & replace with your new parameters.
/dev/disk2s1
is your existing 1st partition on that drive, disk2
is what it's looking for. I'm not actually certain why dev/disk2
wouldn't work, but it doesn't.
That would make your command$ diskutil partitionDisk disk2 1 MBRFormat "MS-DOS FAT32" UDOO 1024M
You can also simplify the command if you like, as far as$ diskutil partitionDisk disk2 1 MBR fat32 UDOO 1024M
& it will still work.
As pointed out in comments, the volume name only needs to be in quotes if there's a space. I'd missed that, my bad.
