I have a UBS drive formatted as fat32 because I need to share it with Linux and macOS. When I want to copy a Linux ISO file which is larger than 4GiB, this was not possible due to the limitation of fat32 filesystem.
A solution is to format that USB drive with exfat filesystem. I will do this on a Fedora 35 machine, but the process should be familiar for other Linux distros too.
# udisksctl status | grep -i usb TOSHIBA TOSHIBA USB DRV PMAP 07086B299E1C4C22 sde # lsblk /dev/sde NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sde 8:64 1 7.5G 0 disk └─sde1 8:65 1 7.5G 0 part # mkfs.exfat /dev/sde1 exfatprogs version : 1.1.3 Creating exFAT filesystem(/dev/sde1, cluster size=32768) Writing volume boot record: done Writing backup volume boot record: done Fat table creation: done Allocation bitmap creation: done Upcase table creation: done Writing root directory entry: done Synchronizing... exFAT format complete!
A quick explanation of what happened above. My USB drive is detected as
sde, and it already has a partition named
sde1. The command used to create an exfat filesystem is
Pretty easy, isn’t it? If you’re wondering why I even bother write this post, good question. I just want to brain-dump, ‘cus just now I totally forgot how to do that. I guess I can be excused since I pretty much work with ext4, xfs, btrfs and zfs mostly nowadays.
