我将 fat32 格式的 USB 驱动器连接到我的系统。dmesg显示：
[ 4057.783200] sd 6:0:0:0: [sdd] Optimal transfer size 33553920 bytes not a multiple of physical block size (4096 bytes)
...
[ 4064.091218] FAT-fs (sdd1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
该驱动器用于 MacOS、Win 和 Linux，因此为 fat32。由于短暂停电，这种情况之前已经发生过几次。像往常一样，我使用 Gparted 检查磁盘，懒得man fsck检查选项：
然而，这一次它不仅仅检查磁盘，还彻底擦除了磁盘。系统日志没有告诉我任何信息：

/var/log/messages并且journald不再有任何帮助。磁盘本身很好，它只是空的，而不包含我存储在那里的数据。
磁盘已卸载。有什么办法可以恢复数据吗？
命令sudo systemctl cat media-pg1-E93B\x2d1A8F.mount报告No files found for media-pg1-E93Bx2d1A8F.mount.我重新安装了磁盘并重新运行命令，但它没有返回任何内容。重新安装后的系统日志：
