What API is available for creating Drive in the Windows File System?

I am mainly looking for an example of an API used, for example, by an external USB hard disk driver that adds a new disk to the file system in Windows.

Thank!

The file system is really implemented by the driver stack. For example, a USB drive is first processed by the USB Mass Storage driver. Since a USB drive can contain several partitions with different file systems, you can have several file system drivers in parallel, and multiple disks can be displayed in Explorer.
