Fatal bug

Make an environment folder of Vmware Player in D drive,
While creating an OS in it and running the OS

At Defraggler Portable,
When I clicked the analysis of D drive,

Defraggler.exe got no response,
Defraggler started writing data to the D drive at maximum speed.

All programs accessing drive D
There is no response and the access from the Explorer to the folder inside the D drive also becomes unresponsive
It was inaccessible.

When I clicked "End Process Tree" of Defraggler from Task Manager, access was refused.

I felt the danger of data, so I immediately pressed the reset button on my PC.

The work state that was working on the virtual machine has been discarded.
※ The work situation when there is no virtual machine response,
30 hours passed, remaining 5 hours.
