Hi, this isn’t a moan, just a request for support 
Avast seems to like to check what’s going on … here’s a snippit of a trace I did on my HTPC … which may or may not be the reason the main HDD never spins down on my HTPC 
Keep up the good work fellas, and thanks in advance for any help
BTW whether or not this is resolved, Avast is fantastic
