I own a 160GB Dell Mini 10v, and I recently noticed an annoying ticking sound coming from my hard drive.
From what I've read, it was shortening the life of my hard disk and smartctl showed that my Load_Cycle_Count was through the roof.
Not sure if any other Dell Mini owners are having this problem, but here's what fixed it for me:
WARNING: This will increase the risk of damaging your hard drive if your netbook is dropped, so use this only if you're sure you need it.
Code:
hdparm -B 254 /dev/sda
Add that to your rc.local, etc if you need it.
If anyone has a better fix, please let me know.
Thanks
