Strategische optionen definition
Perhaps it is not CrystalDiskInfo on it's own, but rather a combination with a driver or software specific to my setup. Incidentally, it is not a coincidence that I have my CrystalDiskInfo set to Auto Refresh every 1 Minute.
I tested with every 3 Minutes and then the clicking was every 3 Minutes. Now, with CrystalDiskInfo NOT RUNNING, if I leave my drive Idle for a long while, and then start any activity on it, I will have to listen very closely (physically have to lean into the PC too) to barely hear the head loading. And my PC is very quiet, as I have made every effort to have the quietest possible air cooled PC.
