Beginning with V1R5, a scratch request with no media type specified, and a 3592 Model E05 drive is allocated, if EFMT2 or no recording technology is specified, there are now 3 applicable scratch categories (MEDIA9, MEDIA5, and MEDIA7). Otherwise, there are two applicable media types for the 3592 Model E05 (MEDIA5 and MEDIA7).

As with existing WORM media types (MEDIA6 and MEDIA8), WORM media is not mounted by default and must be explicitly requested through Dataclass (this includes MEDIA10).
