This is for a Dell Inspiron E1705/9400.  I'm using a non-OEM disk (a 
Hitachi 320 GB drive).

Note that matching on "MP061" doesn't work -- it needs to be "MP061*" 
due to the way dmidecode seems to return the data (with a bunch of 
spaces after the tag).  Hence I've attached the data rather than merely

I've only had this thing a month or so and already had over 70,000 
unload cycles.  Ick.

I didn't count it for a full hour (I put the workaround in place over
a month ago); it looked like it was incrementing something between 2
and 5 times per minute, as I recall.

Can you please measure it again and post the result?

Just one more question.  What do you mean by non-OEM?  It didn't come
with the listed harddrive?

   Just one more question.  What do you mean by non-OEM?  It didn't come
   with the listed harddrive?

Correct.  I purchased and installed the hard drive after I bought the
laptop.

Anyway, here's my smartctl output.  My laptop was mostly fairly idle
during these 2 10-minute periods, although I was doing a few things
(an OOo document, for example).  It's a bit more than twice a minute:

# while true ; do smartctl -a /dev/sda |grep 193; sleep 600; done
193 Load_Cycle_Count        0x0012   093   093   000    Old_age   Always       -       72102
193 Load_Cycle_Count        0x0012   093   093   000    Old_age   Always       -       72124

Hello,


Ah... thanks.  I Robert's case is like that too and I don't think
storage-fixup is the right place to deal with that.  It seems we'll need
something which is somewhat intelligent and more dynamic.  I'll talk
with Bruce whether we can do something about it using smartd.

Thanks.
