TechTool Pro now knows which attributes contribute to drive failure, and will report a failing result before the drive fails completely. Previous versions of TechTool Pro reported the overall status of each attribute, but some attributes don't contribute to the failure of a drive. In the failed state, often there is little or no time to back up data before the drive fails entirely. In most utilities, just the overall results - passed or failed - are reported to the user. SMART Check - Hard drives include a technology called SMART (Self Monitoring, Analysis and Reporting Technology) which can inform a computer about the health of its hard drives.The Partition Repair tool does just what it says, repairing the partition maps or drives where needed. This includes hidden partitions which keep track of your Mac's startup process.
