One thing you'll want when the number comes back, because the raw value alone won't tell you much.
Load_Cycle_Count is meaningless in the absolute. Divide it by Power_On_Hours (smartctl prints both). Under ~1 cycle/hour is normal. Ten or more per hour is the aggressive-parking pattern, and that's when it's worth acting.
If it is that: the control is APM, via `sudo hdparm -B /dev/sda` to read it. Straight from hdparm's man page, and the threshold is sharper than most write-ups make it: values 1-127 permit spin-down, 128-254 do not, 254 is maximum I/O performance, 255 disables APM entirely (most drives support that, not all). So the meaningful line is 128, not "a high number".
Two honest caveats. It doesn't survive reboots by itself — on Debian-based systems (so antiX) /etc/hdparm.conf is where it goes to persist. And it isn't free: a drive that doesn't park spins more, which costs battery. On a netbook that may be the wrong trade, and only you can weigh it. If the count is already low, leave it alone.
If instead you see Reallocated_Sector_Ct or Current_Pending_Sector above zero, ignore everything above — that's the other branch and the only move is copying your data off.
Curious what the numbers say. If you post them I'll read them.
