Formatting an SD card as exfat

December 17, 2015

On Android, by default SD cards with 64M or more on them are formatted as exfat, while smaller cards are formatted as fat32. But what if you want to force an SD card to be exfat? Here’s how to do it. You’ll need a Linux box.

  1. sudo apt-get install fuse-exfat exfat-utils
  2. Partition the card if it’s not already partitioned
  3. sudo mkfs -texfat /dev/sdf1

Mostly this post is to remind me that the new format is called exfat, since I keep forgetting that.
