*Note that a trial version of TechTool Pro is no longer available*. *TechTool
Pro* is a powerful utility for testing, repair and maintenance of your Mac.
This even extends to disk defragmentation (something usually associated with
Windows) and data recovery. TechTool Pro certainly comes with a good pedigree
- TechTool Deluxe which is the most complete version of TechTool available,
is part of AppleCare's Protection Plan. So if Apple trust it, it must be
quite good. To perform simple Diagnostics and Repair just use the *Check
Computer* feature to perform a complete test. This includes a SMART test of
the computer's built-in hard drive to check for impending drive failure, a
RAM test and a check of the disk directories. *Volume Rebuild* is similar to
the Permissions Repair found in OS X Disk Doctor and basically optimizes
critical data structures and will repair any problems. TechTool Pro performs
also optimizes via file optimization and volume optimization consolidates the
free space on a hard drive. Meanwhile *Data Recovery* offers several methods
of data recovery from corrupted drives while a feature called *Trash History*
can track the location of deleted files. One of the more unique features of
TechTool Pro is *eDrive* which is a bootable Mac OS X partition which
contains TechTool Pro and a small copy of your OS that you can use when
performing emergency recoveries. There's no need to reformat your hard drive
during this process and eDrive provides an extra secure layer of protection
should the worst happen. Use this in addition with TechTool Protection system
preference which allows you to schedule checks and even e-mail alerts, and
TechTool Pro is a very powerful package. *Its not the simplest solution out
there but its certainly one of the more powerful. TechTool Pro will appeal to
power users more than anyone but there's something for everyone in
it.*Download *TechTool Pro 6.0.5* in Softonic
