Thanks for the replies.

Well, that won;t exactly preserve your files that are not erased, or your
partition tables, of your MBR or anthing. Why not just take out the drive
and throw it away.

Hi all,

I'm about to send my notebook away for repair, and I would like to make
sure that the data I've erased from the HD is not recoverable.

Is there a Linux tool for overwriting unused disk space (not existing
files) with garbage, in order to make the old data unreadable?

My filesystem is ext3.

Thanks in advance!
