About the issue with the Toshiba L735-101 (needing at least -B 128
otherwise the disk spins down every few seconds even with latest
patches), this might be related to the fact that Linux has hard times -
probably an issue with Toshiba BIOS - to find out whether the system is
on AC or battery: sometimes the battery isn't displayed, the machine
never goes to slip when lid is closed but can be sent to sleep forcibly
by menu, the "vision" that Linux has about the AC/battery status changes
once the AC adapter has been plugged then unplugged etc.
In this situation I assume that the hdparm script may not be able to
determine what set of parameters it should use (AC/battery/whatever).
But I believe that even in such "limit" conditions, we should take any
provisions to not use any parameters that could possibly result in a
damage to the hardware. That definitely doesn't compare with saving a
few milliamps for gaining a small % of battery duration on most systems
"that it wouldn't break"...

Title:
[Precise] [Hardware-killer] HD restarts every few seconds
Status in “hdparm” package in Ubuntu:
Confirmed
Bug description:
Hi,
After update from Oneiric to Precise Beta 1, kernel 3.2.0-18-generic,
I notice that, when on battery, my Dell XPS M1330 laptop has its HD
spin down, then restart, very, very, very often, which means several
times per minute.
At this pace the HD won't live long, and this reminds to me a problem
we had few years ago with "disk killers" linuxes that were
unloading/reloading the HD heads much too often, killing disks in a
couple of months.
So I prefer to ring the alarm bell early...
Upgrading from Oneiric to Precise I didn't change any power management
parameter, but it definitely didn't do this before (and still doesn't
do this on other distros I have on multiboot, so that's no hardware
issue, only Precise does that on my machine...)
