To Jan: The log file shows gparted failed to create a new file system since the partition is mounted.
To kurt: Thanks for your advice. Now I demonstrate the scenario again: (assume to format partition A) Step 1. start gparted Step 2. mount the partition A (I just want to check the files on partition A again.) Step 3. right click partition A in gparted and choose another partition type from the "Format to" menu. Step 4. click "Apply" The question might be gparted doesn't refresh the disk status and change the menu when partition A is mounted. And when i refresh the disk status using "Ctrl+R" after step 2, the "Format to" menu is disabled on partition A and the "Umount" menu is enabled . Then i can umount and format partition A successfully. So I suggest that gparted monitors all partitions' status itself rather than let users to do it manually. I think it will be a good improvement on user operation. -- umount partition issue https://bugs.launchpad.net/bugs/579098 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
