How to create exFAT on USB drive with FreeBSD

Why use exFAT for USB drives and removable drives?

The exFAT, short for Extended File Allocation Table, file system supports very large volume sizes, which is one of the reasons, that it is used for larger USB drives and SD cards. exFAT does not have the 4 GB file size limit, that the FAT32 has. exFAT is compatible with different operating systems and physical devices.

Create exFAT on USB drive or removable drive.

If the the drive is already mounted, then unmount it, before creating the exFAT file system.

# umount /dev/da0

Create the exFAT file system on the removable USB drive. The exFAT file system willl not have a partition scheme. This ensures compatibility.

# mkexfatfs /dev/da0
mkexfatfs 1.4.0
Creating... done.
Flushing... done.
File system created successfully.

Confirm, that it mounts.

# mount.exfat /dev/da0 /mnt
FUSE exfat 1.4.0 (libfuse2)

Vordingborg Festuge 2024

Pictures from Vordingborg Festuge 2024

This is some of the pictures, I shoot of bands and guests, from the annual music festival Vordingborg Festuge 2024.

About the pictures

Conditions were challenging heavy clouds and rain. This did not leave much light for capturing pictures.

I used a handheld digital camera with a 70-200mm zoom lens. I used an optimal balance between high speed exposure and narrow depth of field. I used my own custom in-camera picture profile settings for capturing true colors as seen on site. I did not not apply any editing, filters nor generative artificial intelligence to the pictures.

Would you like prints or digital copies?
