Now,I use the win32.winioctl.d file,find :IOCTL_STORAGE_EJECT_MEDIA ' Value is 0x0202,if you use it ,will get the error value 50.(by GetLastError()).

It should be 0x2d4808.If you use it ,it works ok.

Why have this kind of mistake?

maybe just a bug

but https://github.com/Diggsey/druntime-win32/blob/master/winioctl.d seems to be correctly defined

IOCTL_STORAGE_EJECT_MEDIA = CTL_CODE_T!(IOCTL_STORAGE_BASE, 0x0202, METHOD_BUFFERED, FILE_READ_ACCESS),

You can test to remove a USB by it,use  '0x2d4808' will be ok,but '0x0202' will be failed .

Sorry,I've known what's wrong with it.
Should do similar to C++:  import win32.winioctl;
Don't similar to c#:  public  uint IOCTL_STORAGE_EJECT_MEDIA = 0x2d4808;

so it was your fault not using the IOCTL_STORAGE_EJECT_MEDIA as defined in the import???? where do you get the 0x0202 value from????

your questions, problems AND solutions are always very hard to understand
