Shalom,

1) Do an OS install, include the target disk in the install.

2) Use a hammer. We physically destroy the disk.

3) Use dd command of=/dev/dsk/yourdisk

Re: Erase data on disk

Hi eric:

If you choose to write zeros over a disk, you will greatly speed up the process by using a large block size and a raw device:

# dd if=/dev/zero of=/dev/rdsk/cXtYdZ bs=1024k

That said, sophisticated technologies can still read data overwritten ten or more times. A hammer and some strong acid work better in this case.

If the disk merely contained an operating system, simple means serve to render it useless.

Regards!
