Is it necessary to run DiskMagik on a manual defrag if using the Proactive or background mode?
The Proactive or background mode is sufficient to maintain your hard drive in full defragmented mode. However if you install or delete a lot of files, it may be worthwhile running a manual defrag to reorder the files for more optimum placement. Diskmagik’s proactive mode may not be suitable with certain video games and other software which write large amounts of data continuously to the disk.
