CTSDEU - Data Erase

The CTSDEU utility erases residual data remaining on a tape following one or more valid files. By using CTSDEU, you can prevent unauthorized access to potentially sensitive data left on the end of a tape from previous use. Usually this is performed before a tape leaves a secured area. When a multivolume data set is created, every volume except the last is completely full of data. As a result, only the last volume in a multivolume dataset requires security erase processing. If a program creating multivolume datasets issues a FORCE-END-OF-VOLUME command before filling each volume, then security erase processing might be required on other volumes. In this case, specify the ALL parameter. The ALL parameter directs CTSDEU to attempt a security erase on every volume in the multivolume set.
