Prevent identity theft by thoroughly erasing the information contained on your hard drive.

To complete this How-To you will need:

A computer with internet access
A drive-erasing tool
A blank CD or USB drive
An external hard drive (optional)

Step 1: Back up everything

Before you erase your hard drive, back up everything you want to save on CDs or an external hard drive.

Step 2: Download a drive-erasing tool

For a PC, download a dedicated drive-erasing tool for free online.

Tip: Look for a tool that is recommended on reputable tech web sites or by the manufacturer of your computer.

Step 3: Create a boot disk

Create a boot disk using a CD or USB drive by following the instructions from the drive-erasing tool.

Step 4: Follow instructions

Read and follow the instructions for the drive-erase tool to erase the hard drive by overwriting the data.

Step 5: Erase a Mac hard drive

Erase the hard drive on a Mac by going to Applications, Utilities, and opening the Disk Utility. Select the drive in Disk Utility, click the Erase tab, then Erase Free Space.

Step 6: Using Disk Utility

In the popup menu, choose Zero Out Deleted Files, 7-Pass Erase, or 35-Pass Erase. 7-pass takes seven times longer than the zero out option, and 35-Pass takes 35 times as long, since they write over the disk seven and 35 times, respectively, ensuring you have thoroughly cleaned the drive.
