IIRC, STK has a utility that overwrites the backend disks similar to ICKDSF (and others).
<snip> If your DASD does anything similar to the STK SVA 9500 I have, MVS software becomes irrelevant. Every time a track is written to, the hardware places the entire track's data in a new set of "sectors" on some physical hard disk in the box. All this is done invisibly to MVS. You basically never know where the physical write will go to and therefore cannot tell if there are any sectors which have not been over-written. Unless the DASD hardware comes with something akin to "data destruct" with some kind of certification regarding how it is implemented, you really cannot do a DOD acceptable clear. I doubt if it would satisfy HIPAA or SOX either. </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
