I'll be getting a new laptop tomorrow and I wanted to delete my complete hard drive.  I do not want to turn in the HD and have my employer go through my files.  

What's the best way of doing this?  Preferably to whatever the latest standard is presently.

Use a drive scrubber to wipe over your data with 1's and 0's.  The data will never be accessible.

There are many to choose from.  All for free.

Cyber Threats to Small Businesses (Part 1)

This past May, Webroot surveyed more than 600 IT decision-makers at medium-sized companies to see how these small businesses perceived new threats facing their organizations.  Read what Webroot CISO, Gary Hayslip, has to say about the survey in part 1 of this 2-part blog series.

You have to use a wipe program. A simple deletion is not enough.

You can use a portable software, so you dont need to burn cds etc...
Otherwise install on the same disk. It will overwrite data you will delete anyway :)

An advanced shredding algorithms (Dod 5220-22.M, US Army, Peter Guttman) to securely wipe data.
PREFER MULTIPLE PASS (2 or more)

Some software you may try:

I like DriveScrubber.  One advantage if you buy it ($30) is that it can be installed on your replacement laptop.  It has a utility that will scrub an individual file.  If this is a laptop computer from work, and you occasionally have personal information stored on it, you might like this feature, as it does a scrub on an individual file that you want to delete.  Just using Windows to delete the file only deletes the pointer to the file, not the file itself.  The file remains on the disk with the space allocated as available, but the space won't actually be overwritten until something else is stored there (maybe never).  Although I occasionally want to scrub a drive, I find that Drive Scrubber is most useful for the individual files.

Here's the link:

Remember to wipe "free space" as there can be hidden files that you delete days ago, and where not overwritten by newer files!

i personally prefer Active Kill Disk.
http://www.killdisk.com/features.htm

free, has multiple algorithms (17 to be precise) to choose from, depending on your need, self bootable.
and best of all, it wipes the entire physical disk.
