Quando uso smartctl -s off /dev/sda com privilégio de administrador, o suporte SMART é desativado:
C:\Program Files\smartmontools\bin>smartctl -s off /dev/sda
smartctl 6.5 2016-05-07 r4318 [i686-w64-mingw32-win8.1] (sf-6.5-1)

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
SMART Disabled. Use option -s with argument 'on' to enable it.
Isso é confirmado usando smartctl -a /dev/sda/ :
C:\Program Files\smartmontools\bin>smartctl -a /dev/sda

Mas quando eu reinicio meu computador, a verificação SMART volta novamente. Por que é que?
