Laptop-mode-tools and hard disk

Question

I use laptop-mode-tools to save battery on my Asus TUF A17. I works fine but not for the hard disk : this one is going too much to sleep and wake up after every 10 seconds. So the Load_Cycle_Count is increasing too much.

meloli@Asus-A17:~$ sudo smartctl -a /dev/sda | grep Load_Cycle_Count
193 Load_Cycle_Count        0x0032   098   098   000    Old_age   Always       -       4321

I tried sudo hdparm -B 255 /dev/sda or sudo hdparm -B 254 /dev/sda wbut it does nothing...

The only things who seems to work is using spindown time

meloli@Asus-A17:~$ sudo hdparm -B 254 /dev/sda
/dev/sda:
 setting Advanced Power Management level to 0xfe (254)
 APM_level      = 254
meloli@Asus-A17:~$ sudo hdparm -S 242 /dev/sda
/dev/sda:
 setting standby to 242 (1 hours)

I tried something like this in /etc/hdparm.conf but I does nothin when using battery.

/dev/sda {
#   apm = 127
   apm_battery = 254
   spindown_time = 241
}
command_line {
    hdparm -S 241 /dev/sda
}

Everything works fine when using AC.

How to get my hard disk not to go to sleep too quickly when using laptop-mode-tools ?

Thank you.
