I have a hard drive connected to my W10 PC via USB.
It has a green light on it which I assume indicates activity?
Anyway - I just noticed it is blinking madly even though the PC is
sitting on, but unused.  Scares me,
What does this mean?  Why is there activity?  Someone is not on my PC
accessing my drive is there?  I hope this is not a dumb Q.
Anyone?
Pete
