I checked the source code and found usb-creator can only calculate the free space for a mounted partition, however the newly formated partition isn't mounted.
So to fix the issue we could mount it automatically after the formating. In the attached patch this job is done in the dbus method Format() in usb-creator-helper. In my own test it works fine. ** Patch added: "auto-mount-after-format.patch" https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1413494/+attachment/4303499/+files/auto-mount-after-format.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1413494 Title: Free partition space isn't correctly updated after erasing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1413494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
