I submitted this message to linux-ide-u79uwXL29TaiAVqoAR/hOA at public.gmane.org
Since there has been no response so far, I added my system to the table in
<https://ata.wiki.kernel.org/index.php/Known_issues#Known_affected_devices>
I find it scary that Linux might well have eaten one of my disks. I admit
that it might not be a fault of Linux, but it sure would be nice if
something like palimpsest noticed and warned that the Load Cycle Count was
rising in a scary way and sugested what could be done about it.
I've added "hdparm -B 254 /dev/sda" to /etc/rc.d/rc.local on my CentOS
6.3 system.
Anyone else experiencing this problem?

Subject: HP Compaq 2710p notebook suffers too many head unloads
The head unloading problem is as described here:
<https://ata.wiki.kernel.org/index.php/Known_issues#Drives_which_perform_frequent_head_unloads_under_Linux>
I am intending that this report contributes to that table.
(Aside: many of the links in that table are broken.)
My computer is an HP Compaq 2710p notebook/tablet.
<http://h18000.www1.hp.com/products/quickspecs/12718_na/12718_na.html>
It has a Toshiba MK8009GAH 80GB 1.8inch 4200RPM Hard Drive. I
recently replaced a similar one that failed, perhaps due to excessive
head unloading. The replacement disk was used.
When I got it:
5349 Power_On_Hours
49711 Load_Cycle_Count
9.29 cycles / hour
Now:
5698 Power_On_Hours
87423 Load_Cycle_Count
While I've had it (i.e. delta of above POH and LCC numbers):
349 Power_On_Hours
37712 Load_Cycle_Count
108.06 cycles / hour
It sure looks like Linux is worse than whatever system used the disk
before I got it.
(For what it's worth, my failing disk reported 21252 Power_On_Hours and
526387 Load_Cycle_Count. This isn't really useful data since I don't
know what OS was used with it before I purchased it last summer.)
"hdparm -B 254 /dev/sda" stops the count running up.
"hdparm -B 255 /dev/sda" does not.
The OS I use on this system is x86-64 CentOS 6.3. I don't actually
know why it is accessing the disk 108 times per hour when the machine
is mostly idle.
Here is a transcript of dmidecode and hdparm output.
Note that Advanced power management level is reported as 254 because I
set it that way. The default was 128.
