TechTool Pro's hard drive tools are second to none. Create an emergency startup partition on the active system volume using TechTool Pro's eDrive, without ever having to boot from a DVD. Perform a SMART test on your internal ATA or SATA drives to detect changes in reliability, and repair corrupt or damaged HFS+ volumes, including those in newer solid-state devices (SSD's).
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.
