Today I helped out a customer who was having an issue with their MacBook Pro. They had Drive Genius 3 installed on their MacBook with an external drive plugged in for a TimeMachine backup. DrivePulse (a new feature of Drive Genius 3) reported that there was a error with the Time Machine backup drive and that the Mac HD also had errors . Drive Genius 3 reported this error prior to the drive failing or the backups failing. If the user did not have Drive Genius 3 installed it would have gone unnoticed. until it failed. The DrivePulse feature within Drive Genius is a great tool that gives an early warning to drive failure. It’s early warning can save you time and headache as it alerts you when there is a problem with one of your Mac hard drives-
