The value of 35 that you are talking about is another value that has nothing to
do with it.
you refer to this line
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED
WHEN_FAILED RAW_VALUE
193 Load_Cycle_Count 0x0032 035 035 000
Old_age Always - 656598
The last column is the raw value, probably this is the absolute load cycle
count, but who knows.
*If* the raw value is the absolute count, your disk had 656598 cycles
VALUE and WORST are normalized views of the raw value. If VALUE is reaching
THRESH than the disk will die soon.
VALUE was probably 100 when the disk was new and was/is decreasing since then.
If S.M.A.R.T. is right, you have 1 third of the load cycles left. Oh, but who
says that it decreases linearly?
I did a search for your drive (I hope I got that right)
http://www.techhypermart.com/samsung-hm641ji-2-5-640gb-mobile-hard-disk-drive.html
says
- Load/Unload Cycles: 600,000
yours is at 656598, this could mean that its over the specificated load cycle
counts yet.
Note that this does not correlate with the 1 third from above, sadly.
Another strange thing - your APM is at 254 according to the output from hdparm
It was mentioned that the APM level is not guaranteed to survive a reboot. Some
OS's could set it at boot time, some will not.
It could be that a OS that does not make these clicking sounds is a OS that sets it at
254 at boot time. You will have to retrieve the value with the problem-os. Maybe you
retrieved this value while the "good" OS was running, I do not know.
I encountered drives which APM was not changeable at all
Also note that the interpretation of the raw value is not standardized.
We are fishing in muddy waters without technical specifications from Samsung.
I am getting more confused now. I can assure you that I never changed my
OS before since I initiated this thread. So, all the data is coming from
one single OS from a single machine.
Assuming linearity, this means that I spent 2/3 of my hard disks life
within 2 years. And after a year, my hard disk will die. If it is
nonlinear, than it is not predictable, it can die before a year or after
a year? This makes me start to worry, perhaps I should consider using
another laptop then?
I already posted the model I am using, and I am repeating this:
Laptop Model: HP Pavilion dm1 3240ca
Hard Disk: Samsung SpinPoint M7E (AFT)
In case you're interested I can post other info about its identity from
gsmartcontrol. From what I see, the link that you're included about my
hard disk is not exactly matching the model I am using (your link gave
me an external hard disk).
http://www.amazon.com/SAMSUNG-HM641JI-Spinpoint-internal-notebook/dp/B0053OVVFQ
but the above link is more relevant I believe. From the reviewers of the
product, I am starting to believe that my HD will die soon...
Nevertheless, if I use the hdparm method, I will be able to eliminate
the click at least?
