Use TechTool Pro's Volume Cloning to create exact duplicates of your volumes for trouble-free archiving. Plus, TechTool Pro helps you recover deleted files and lost data. If bad blocks are found when scanning your hard drive, you can identify and restore the corrupted files within them from previous backups you have archived.

To help keep your Mac running at peak performance, use TechTool Pro to optimize your volumes after defragmenting your files, or to repair disk permissions which may prevent problems accessing applications or files on your Mac.

TechTool Pro also helps with device management within your local area network (LAN). To monitor the configuration or security of your LAN, TechTool Pro displays Bonjour supported devices and active services, and helps track devices no longer available to the monitored network.

Diagnostics and Repair
Use the Check Computer feature to perform a complete diagnostics check of the computer and the Macintosh formatted hard drives with one click of the mouse. This includes a SMART test of the computer's built-in hard drive to check for impending drive failure, a test of the computer's available RAM, a check of the disk directories, and much more. If problems are found, advice is provided on how to proceed to repair the problem. Use Check Computer regularly as a part of a preventive maintenance program.

Volume Rebuild
In addition to testing the disk directories of hard drives, TechTool Pro can also perform a complete rebuild of them. This optimizes these critical data structures and, on a corrupted drive, repair any problems. Use volume rebuild to keep your hard drives operating at their peak performance.

Optimization
TechTool Pro performs both file and volume optimization. File optimization consolidates each individual file into a contiguous area of the hard drive. Volume optimization consolidates the free space on a hard drive. Optimizing enhances the overall performance of your drives and simplifies the file storage layout.

Data Recovery
TechTool Pro includes several methods of data recovery. Use them to recover data from corrupted drives that don't mount on the desktop and save the data to another location. Use the Trash History feature to track the location of deleted files and increase the chance of their recovery in the case of an accidental deletion.

eDrive
One of the unique features of TechTool Pro is the eDrive. This is a bootable Mac OS X partition containing TechTool Pro and a small copy of your system that you can use when performing regular maintenance or in the case of an emergency. It is created on one of your hard drives without the need to reformat it.

Protection
TechTool Pro includes the option to install the TechTool Protection system preference. This is where you configure automatic functions that operate in the background. In particular, you can configure Protection to track deleted files, monitor the free space on your hard drives, save backups of critical directory data to help with recovery in the event of drive corruption, and to monitor the SMART routines of your hard drives. If problems are found, Protection provides an onscreen alert and can even be configured to send an email alert.
