在 Windows 10 中使用 diskpart 时，我只能看到一个分区，该分区是我在 .vhdx 文件中创建并安装 Windows 的，但这是使用该实用程序从安装媒体启动时看到的唯一可见分区。我决定看看 Dr. Web 救援 CD/USB 显示的内容，我发现的内容没有意义。首先，我使用命令 fdisk /dev/sda，结果与 diskpart 匹配，但当我运行 fdisk /dev/sda1 时，似乎有四个附加/子分区，大小（不知何故）比我机器中的 500G HDD 大得多。
分区是如何进行的？如何才能拥有比物理驱动器的容量大得多的分区？
如何检查驱动器上是否存在其他不可见的分区？

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
