How to see who wakes up the harddrive (HDD) from sleep?

Usually I have my D: drive sleeping because it is too loud.
But sometimes, without obvious reason somebody wakes it up.

To see who does that, you need to  install the Sysinternals Process Monitor (Microsoft website).
At startup you need to cancel the filter dialog that will be presented.

In the program, under the Filter main menu, tick Enable Advanced Output and Drop Filtered Events.
Then in the same menu, create (Ctrl+L) a filter rule like this:
          "Path contains D:\", then click the "Include" option.

Now keep the program running until you see who accesses the D: drive.

PaintShop Pro won't save images as JPG (Fixed)

Today I was not able to save anymore images in PainShop Pro as jpg (png will work). PainShop Pro will simply freeze if I try to do this.

The issue: a clipboard monitor called PureText was conflicting with PainShop Pro. Closing the program solved the issue.  

I have no clue why the programmers of PainShop Pro chose to hook to the clipboard while saving the output as JPG but obviously is not only pointless but also poorly implemented.

Case solved.
