Many computer users store data on external drives. There are several reasons for doing this. For example, data backup sets are often stored on externals drives. Additionally, some computer users store their original documents on an external drive. This allows the data to be stored separately from the OS and program files. Should the main drive crash and hard drive recovery is needed, the external can be moved to another computer, eliminating the need for emergency data recovery, including digital picture recovery.

Once the main drive is repaired, the external drive can be reattached. The external drive should be defragged, as well as the internal drives. Our award-winning program, Drive Genius 3, is a great way to maintain all of your drives, both inside and out. The program is actually a toolbox of maintenance programs and the defrag routine is a powerful routine.

When you run the defrag diagnostics, the program scans your drive, searching for fragmented files. The results are displayed graphically. Areas and files that need to be defragmented are displayed in red. The defrag program will make a suggestion as to whether the drive needs defragged.

If you choose to defrag the drive, you will be asked to reboot the computer. The routine runs before the computer reboots into the OS, ensuring that no files are in use. Files that are in use cannot be moved, making the process less efficient. Depending on the amount of fragmentation, the process could take hours; therefore you need to run it during a down time.
