The importance to defragment your Mac hard drives

Mac users always ask, "How can I speed up my Mac?" If you want to speed up your mac, you can do it with the most-awarded mac utility software, Drive Genius 3- Your Mac hard drive has tens of thousands of important computer files on it. Your hard drive, also referred to as your Mac HD, is where all your digital pictures, emails, work files, videos and other files are stored. With so many important files being stored in one location, it's important that you take steps to make sure your Mac is not only running smoothly and optimized for peak performance, but also that the files themselves are managed better so that if there ever is a need for emergency file recovery, you will stand a better chance at recovering your files.

Defragging your hard drive, also referred to as optimizing your hard drive or Mac, is an important task to run on a regular basis. Defragging your hard drive with Drive Genius will improve the performance of your Mac as well as improve the recovery chances should your Mac become corrupted.

Please note: Due to the changes Apple made in Mavericks 10.9, the Live Defrag option is not available. Please refer to our Frequently Asked Questions to see how you can defrag your system on Mavericks 10.9.

Increase performance

Better performance for your Mac hard drive is accomplished by defragmenting each file that the Mac Operating System skips. The Mac OS only defrags files if they are under 20mb in size. You have thousands of files larger than that threshold, including most of your important files like pictures and videos.

Drive Genius' award-winning, used-by-apple defrag tool makes the file one contiguous file again. This is great for performance as your Mac doesn't have to piece fragments of files together upon opening it. Also, this is great for recovery, should your Mac crash.

Recovery of a single, contiguous file is much more successful and likely compared to recovery of a highly fragmented file. In other words, if your drive contains a lot of fragmented files then the recovery success is usually lower, compared to a drive contains mostly unfragmented files.

Number one most-used Mac defrag tool

So when someone asks, "I need to speed up my Mac. What should you do?" one answer would be to clean up the Mac hard drive with a defragmentation routine. Drive Genius 3's defrag tool is the number one selling, most-used Mac defrag tool for Mac OS X. Apple has been using it at the Genius Bar for over 5 years now.

Reorganize those larger files

Drive Genius 3 will reorganize the larger files and defrag them (consolidating the file into one contiguous file), improving seek and opening times. This reduces wear on the Mac hard drive because the read/write heads do not need to travel as much across the media when searching for a file. Drive Genius 3 also compacts the larger files to allow them to be saved without fragmentation.

Clean Up my Mac

Over time your Mac fills up with an abundance of large, unnecessary and unorganized files. Drive Genius' DriveSlim® tool is a great solution to keep your Mac hard drive clean and organized.

Free Up Hard Drive Space

Ever wonder how many copies of the same file you have on your hard drive? Duplicate File Search and Delete locates duplicate files and replaces those duplicates with an alias.

Large File Search and Delete

Your Mac is loaded with large files that are filling up your hard drive. Large File Search locates the very large files that are taking up space on your hard drive. This could be large video file that came preloaded on your Mac or some funny email attachment someone sent you. It is likely that you are not even aware of these files and Large File Search helps you keep tabs on what files are on your hard drive, allowing you to mark and delete the ones you no longer need.

Multi-language Slimming

Remove unnecessary language support and just select the ones you want your Mac to support, and delete the others (that you don't speak).

Universal Binary support removal

When Apple made the transition to Intel-based Macs, applications had to be made in a way that supported the new Intel-based Macs as well as the older PowerPC-based Macs from years back. If you're on an Intel-based Mac you are probably never going to revert back to an older machine that needs Universal support, so why not free up the hard drive space of those support files? DriveSlim™ makes it easy to trim all those down to only support the new Intel-based Macs.



DrivePulse® will monitor the health of your hard drive daily when your computer is idle to quickly check for errors, fragmentation, or bad blocks. When the computer is idle for five minutes, DrivePulse® will perform quick tests to check the health of the hard drive.

Physical problems

DrivePulse® performs a Scan on a disk to search for bad blocks on the hard drive ensuring the physical integrity of the device. DrivePulse® is scheduled to Scan once a week, which takes about an hour to complete and will pause its progress when the computer is active again.

Volume consistency problems

DrivePulse® performs a Verify on the volume to assess the integrity of the catalog and directory structures. DrivePulse® is scheduled to perform a Volume verification once a day, which takes about 2 minutes to complete.

Volume fragmentation

DrivePulse® scans the volume catalog and its files to determine the amount of fragmentation. DrivePulse® is scheduled to check the fragmentation status once a week, which takes about 10 seconds to complete.



Fragmentation occurs on a hard drive when there is not enough free space to continuously write the file on the platters of the hard drive.

As files are created, written, and deleted on the hard drive, there is less consecutive free space to write a complete file. This affects all files including system files and application files which can lead to slow boot times and slow application launches.

Mac OS X automatically reduces the potential for fragmentation for files that meet specific conditions, but may not handle larger files that still cause slow application launches and slow boot times.

The Defrag feature in Drive Genius 3 reorganizes the fragmented pieces of all files and compacts their content into one contiguous block for faster access times. Reorganizing the files into one continuous block improves access time for the file to be opened. Compacting the files allows new files to be written onto the hard drive without data fragmentation.

Defragmenting your drives will lead to faster boot time, faster application launches, and faster access to your large media files.
