Okay, I did "Check file system" and "Test surface" for all drive (non-system HDD) partitions in Paragon Partition Manager overnight. Restart was required, so it restarted and started scanning in terminal/console mode. Today I woke up and... nothing? Paragon Partition Manager 17 launched at Windows startup, but did not show any results. Logs in "C:\ProgramData\Paragon Software\Partition Manager 17 CE" show nothing.
Did it fail? Did it succeed? How many bad sectors were there? What files were found to be corrupted in File System checks? Did it do anything at all? I know exactly nothing. How do I view actual results of "Check file system" and "Test surface" after reboot?
