Hard Drive Cleaning

Sup /tech/

So, what do you guys use to remove history from your computer. I am getting a new computer, and I have files on this I want to completely get rid of. I deleted them with recycle bin, but I know that still leaves traces. What kind of software should I use to get rid of deleted stuff for good?

Stop being a cunt. 

All anyone needs to know about cleaning a hard drive is

1.  Foirmatting doesn't actually clean it - it just gets rid of the index, not the files.

2.  Any simple program which starts at the beginning of the disk and writes zeros or ones till it gets to the end of the disk will do the job.  You need to run it ONCE, not 35 bajillion times.
