警告：驱动程序描述符表示物理块大小为 2048 字节，但 Linux 表示为 512 字节

我的笔记本电脑安装了 Lubuntu 18.04，我通过可启动闪存驱动器启动实时 Lubuntu，然后检查分区和文件系统。

以下警告是否存在需要解决的严重问题：“警告：驱动程序描述符表示物理块大小为 2048 字节，但 Linux 表示它是 512 字节”？

这是什么意思？是否是磁盘、分区、文件系统或逻辑卷的问题？

我该怎么办？谢谢。

以下是两种对我有用的方法：

Linux 最简单的方法是以“Disk”开始，然后以“gParted”结束https://askubuntu.com/a/915821/520965

Linux终端中另一种简单的方法：https://superuser.com/a/1153220/601553或者https://unix.stackexchange.com/a/338883/184608
