Just search for 'destroy data' or 'destroy disk'

Do you want the disc to be re-used? If not, do what we do - take it out and hit it on the corner of a cabinet.

Mark Syder (like the drink but spelt different)

the command to re-format a disk is

"mediainit"

Shalom,

mediainit will usually do the job.

There is no 100% reliable way to make sure the data can not be recovered. The NSA has ways of recovering data from disks that have been formatted.

If acceptable I do an OS install on the disk, which makes the average non-governmental entitiy have a tough time recovering the data.

My employer does not trust that. If a disk is no longer useful to us, it is not sold, it is physically destroyed.

Rahul ,

You can use :


# dd if=/dev/zero of=/dev/dsk/c?t?d? bs=1024

# mediainit /dev/rdsk/c?t?d?



Cheers,
Raj.
