TechTool Pro now features a suite of S.M.A.R.T tests (Self Monitoring Analysis And Reporting Technology).

Most modern hard drives now support this industry standard that employs predictive diagnostics and analysis to help foresee a drive failure BEFORE it happens. TechTool Pro 4's SMART test allows you to automatically monitor this vital data and be forewarned of impending danger to your data, allowing you to back up critical information before disaster strikes.

The eDrive feature allows you to create an invisible emergency volume from your existing drive. This new partition is created WITHOUT the need to reformat your current drive and allows you to store a copy of your system, a copy of TechTool Pro and even allows you to make room for other utilities.
