Just started a new pre_clear and noticed these errors related to the hdparm command. Should I be concerned? FYI, the drive is attached to an AOC-SASLP-MV8 card.

Hi Joe, quick question about the benefits of cache_dirs in my particular situation. Is cache_dirs worthwhile if I'm using my UnRAID server to feed an NMT Popcorn Hour where I use a movie jukebox and skin that is stored locally on a drive in the NMT? I could see the benefit if I'm pointing my NMT to the user share of the UnRAID server and I'm using the standard UI of the NMT but I'm struggling to rationalize if I'm getting any benefit with my current setup? Any insight would be greatly appreciated!
