Using Disk Utility to Wipe a Hard Drive First, we're going to look at wiping the contents of a hard drive. It doesn't matter if it's an internal, external, or your Mac's startup drive; using these techniques you can obliterate the contents of the selected drive, making it all but impossible to recover the data. Once Disk Utility launches up, click on the main partition (the one you renamed earlier) of the source Mac. Since Disk Utility can sometimes load up the target Mac visibly higher or lower than the source Mac, it's critical that you have them uniquely named (that's why we renamed the drive earlier). So click on that unique name.
