I gave to my wife a new Samsung N150 Plus Netbook last year. Last month
the hard drive died but the warranty covered a new hard drive, so it was
fine. Now with the new hard drive i was able to hear every 6 seconds
that the heads are parking, and i tried many things and i cannot make it
stop. Now i wonder the first hard drive (the one that died 1 months ago
and my wife lost tons of data) died because of this bug. I know that
this is an old bug now, but in this netbook is defenitly back and i
tried adding this command in /etc/init.d

sudo hdparm -B 255 /dev/sda

even i tried to edit the laptop_mode.conf settings to do no power
management in this hard drive and i had no luck, the packages had
changed over the last versions of ubuntu and i do not know where to edit
to disable this powr management. Now this hard drive has over 16000 load
cycle counts and it keeps growing.

Anyone has starting to experience this? how do i stop this power
management in order to save this drive because the netbook warranty just
expired this month?

regards
