Status in gnome-disk-utility package in Ubuntu: Triaged Bug description: When on Hirsute with the new Samsung provided exfat support, gnome- disks can't create new exfat partitions due to being hardcoded to use the old mkexfatfs program from the exfat-utils package. Instead of the new mkfs.exfat from the exfatprogs package. Hopefully it can detect either and use whichever is available.
