The driver returns an array of DISK_GEOMETRY records for the types of media it supports in the buffer at Irp->AssociatedIrp.SystemBuffer.
Parameters.DeviceIoControl.OutputBufferLength in the I/O stack location of the IRP indicates the size, in bytes, of the buffer, which must be at least (NumberOfSupportedMediaTypes * sizeof(DISK_GEOMETRY)).
The Information field is set to the size, in bytes, of the returned data. The Status field can be set to STATUS_SUCCESS, or possibly to STATUS_INVALID_DEVICE_REQUEST, STATUS_BUFFER_TOO_SMALL, or STATUS_BUFFER_OVERFLOW.
