Sometimes Defraggler gets to say 30% of a drive analysis then it hangs.
The circle icon turns and Task Manager tells me that Defraggler is still running with changing CPU useage etc.
It keeps running even though I have stopped it by Quit selection in Defraggler program..
I use MS OneNote and this has large heavily fragmented files.
If I close Defraggler down and run Iobit Smart Defrag 5 then the drive defrags without a problem.
Next time I run Defraggler it analyses to 100% without a problem
