597 - Strange HDD work after exiting the operation

[Dreamer]

- "define keyboard shortcuts" window, find "Copy: Copy" and change the shortcut to F5
- set FC as copy operation
- copy large file to a different disk (F5)
- rename the copied file
- cancel the operation
= disk is still working (red led and noise)
- click cancel again to close the copy dialog completely
= disk is still working sometimes (red led and noise)

Try to use Move instead of copy and skip renaming the file step to reproduce.

Perhaps it's not the FC issue, but it's really weird, so perhaps other users might help to identify the issue.
