答案1
你的超级块损坏了：Unable to read the contents of this file system!
检查你的文件系统：
sudo fsck.ext4 -v /dev/sdaX
如果您的文件系统已损坏，您应该看到如下输出：The superblock could not be read....
运行mke2fs命令来找出超级块备份：
sudo mke2fs -n /dev/sdaX
通过命令恢复丢失的超级块e2fsck：
您应该使用从mke2fs
sudo e2fsck -b put_the_first_block_number_here /dev/sdaX
重新启动系统然后运行gparted
答案2
