As was mentioned, if you want to stop short of destruction, IBM offers a secure data erase service for disks. I see also that FDRERASE has a certified secure erase function if you have z/OS hanging around somewhere. A Q&D program to use the Data Secure Erase CCW for tapes is sufficient to erase them.
