Firstly, if your system is properly configured, there shouldn't be any data other than the Operating System itself on your root disk. You can simply remove your site specific configuration files and ship it off.

If you wish to be more thorough than that, you can either use dd (dd if=/dev/zero of=/dev/rdsk/c0t0d0 bs=1024k, for example) or run mediainit.

One of the easiest ways - just re-install the OS...

For the most part, a simple rm -rf / does a pretty good job.

Hi Santosh:

The command didn't fail. You wrote 138,932 records until the disk's end.
