And if anybody wonders *why* z/OS does not allow you to do a specific mount of a SCRTCH tape: Your SCRTCH tapes will probably have a 'Fast Ready Category' assiged in your VTS. This means, that when you request a tape from such a category, you intend to write new data on it and don't care about the old data on the tape. Therefor, the VTS will not bother recalling the old data, but will immediately assing you a new blank tape in its cache. If you then try to read, you will see an empty tape. Furthermore, this empty tape will now be *the* current instance of this volser, with your old data still available somewhere on the backend cartridges, but unreachable for you. IBM VTS support seems to provide a paid service to recover the old data in such a case.
