IOCTL_STORAGE_LOAD_MEDIA2 IOCTL (ntddstor.h)

Causes media to be loaded in a device that the caller has opened with FILE_READ_ATTRIBUTES. Because no file system is mounted when a device is opened in this way, this request can be processed much more quickly than an IOCTL_STORAGE_LOAD_MEDIA request.

Input, output, and I/O status block values for IOCTL_STORAGE_LOAD_MEDIA2 are identical to those for IOCTL_STORAGE_LOAD_MEDIA.
