Favorites menu spin-ups my HDD

With SSD my HDD is almost always in a sleep state. But when I open the Favorites menu it spins-up my HDD. On a side note - i have a bookmark for a folder on the HDD in this menu.

Is this intentional behavior?

Are there any ways to avoid this?
And if not, then maybe you can add an Advanced option or just change the default behavior?

It will happen when Opus asks Windows for the folder's icon.

I don't know why Windows doesn't cache the information, but it doesn't.
