I can confirm the problem. You can workaround it by disabling auto-mounting of hot-plugged drives (via System / Preferences / Removable Drives and Media), then creating the file system, and then re-enabling auto-mounting.
But it would obviously be much better if GParted did this automatically when creating the file system, particularly as the workaround is not at all obviously intuitive. -- usb-drive is automaticly remounted during format stopping gparted https://launchpad.net/bugs/65552 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
