GParted disables the 64-bit feature if the partition is small enough not to need it (< 16 TiB). This was done in 2016 because at the time multiple boot loaders (Grub 2 and Syslinux) didn't understand 64-bit ext4 file systems and couldn't boot from them. * Bug 766910 - Multiple boot loaders don't work on 64bit EXT4 file systems https://bugzilla.gnome.org/show_bug.cgi?id=766910 * Only enable ext4 64bit feature when required (#766910) https://gitlab.gnome.org/GNOME/gparted/-/commit/cc7e412bc6ec2e27d049438d2a5d4cf2548cbaae
@ heikorichter If you raise an upstream issue I'll look into it and work out what GParted should do now. * New GParted issue https://gitlab.gnome.org/GNOME/gparted/-/issues/new Thanks, Mike Fleetwood (GParted Developer)
