Drive Genius 2 is a disk defrag utility for Mac that optimizes performance by combining fragmented files and empty spece around them.
If you noticed that your Mac is running slower than before it may mean that your disk is too fragmented. When your file collection grows, chances are some of them will save on different locations on the disk, leaving the file structure non-contiguous.
Drive Genius 2 is a solution for disk defragmentation for Macintosh that can clean up this mess and align displaced files for you. This can save disk reading times and vastly improve overall performance of your system.
Drive Genius 2 can also re-partition your hard drive on-the-fly without the need of reformatting.
Drive Genius 2 is the same software included in ProCare by Apple used at the Genius Bar.
With Drive Genius 2 you can not only defrag and re-partition but also repair damaged partitions or files. The bootable DVD included lets you run repair and repartition utilities even if your Mac OS is broken.
