Default f8 gripe #3: infamous Load_Cycle_Count started hitting my laptop , FAQ?

Now that I hit it with F8, I notice it is so annoying that a single
'hdparm -B 254 /dev/sda' in rc.local isn't sufficient, because when I
resume from hibernate/suspend, it starts incrementing relatively rapidly

Do you know how to query the value that needs to be passed to hdparm -B to
keep the current situation?


Ok, hdparm -I does get it, though perhaps in drive-specific way.


That would make it possible to store the value

when suspending/hiberanting and restore it when resuming/thawing.
But better would be imho, when the drive would not forget the setting in the
first place, maybe this happens because of a change in the kernel.


Or maybe during the 2 days when I let vista live on the laptop between
f7 and f8, it did something nasty, beyond downloading and installing
200+ updates despite explicit requests not to...


Thanks, I think I'm now armed with the tools I need to solve this. I'm
just a bit curious that I haven't seen anyone else run into this, since
it was such a brouhaha for a while there with ubuntu.
