For example, if the disks are SATA, you could put them on a PC running Linux and simpy do the command: "dd if=/dev/random of=/dev/sd?" where "sd?" is the Linux address of the attached disk. This would overwrite the entire disk with random bits. If you are really paranoid: for i in 1 2 3; do dd if=/dev/random of=/dev/sd?;done To do the overwrite 3 times. If the attachment is SCSI, there are SCSI HBAs for PC. Example: https://smile.amazon.com/Dell-Non-RAID-Serial-Attached-External/dp/B0153IR6QY/ . That is a example, not a recommendation. Also, if SAS, https://smile.amazon.com/SAS9211-8I-8PORT-Int-Sata-Pcie/dp/B002RL8I7M/ But erasing the entire drive is likely to make it unusable in the VTL. Have you asked the vendor if the software driving the VTL has a mass erase function? I know that the old IBM Shark had that. > > *George Rodriguez* > > *Specialist II - IT Security* > *PX - 47652* > *(561) 357-7652 (office)* > *(954) 415-7586 (mobile)* > *School District of Palm Beach County* > *3348 Forest Hill Blvd.* > *Room B-332* > *West Palm Beach, FL. 33406-5869* > *Florida's Only A-Rated Urban District* > > > On Thu, Sep 13, 2018 at 2:29 PM Mike Schwab <mike.a.sch...@gmail.com> > wrote: > > > Overwrite each tape with a one track dataset of low values. > > Then overwrite tapes with a very large dataset of low values until VTS is > > full. > > Repeat one track / large datasets with high values and b'01010101'. > > > > Repeat the 3 cycles until desired number of overwrites are accomplished. > > > > On Thu, Sep 13, 2018 at 10:16 AM George Rodriguez > > <0000016eebd7289b-dmarc-requ...@listserv.ua.edu> wrote: > > > > > > The School District of Palm Beach County is finally shutting down the > IBM > > > z10 and all its components. > > > > > > I was wondering if any member the listserve can help me with "wiping > out" > > > out VTL.
