For whatever reason I've recently been looking at the write cache on my drives. All of my array drives are showing write cache enabled except for my parity drive. Is this by design?   When I try to manually set the write cache on that drive using hdparm this is what I get so it never gets enabled: root@unRAID:~# hdparm -W 1 /dev/sdj /dev/sdj: setting drive write-caching to 1 (on) write-caching = 0 (off)   unraid-diagnostics-20190513-1345.zip
