What's New in Version 2.2.13
Results are now also written to the top level of the volume (provided system security allows it).
Most commands in DiskTester now write the results to the top level of the volume, in addition to the longstanding practice of writing them to ~/Library/Logs/diglloydTools/. This file will not be written when system security prevents it, but the results will always be written to ~/Library/Logs/diglloydTools/.
Some commands in DiskTester now emit results files where before those commands wrote only in progress output as the test progressed.
