问题是这样的，由于想更改分区大小，导致分区表整个坏掉，后用testdisk修复，结果是文件管理器能正常打开和使用文件。但是！但是GParted分区编辑器和磁盘常用工具均不能正常识别分区表。
GParted显示
libparted : 2.3======================
无法让分区超出磁盘！
无法让分区超出磁盘！
Partition(s) 1, 2, 3, 5, 6, 7, 8 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.
$ sudo fdisk -l 结果没显示任何分区
