"Count of load/unload cycles into Landing Zone position."
While I could think that commanding the drive to do this every 4 seconds is a bit overprotective that is something that was decided in a committee (my bet) and is best left enabled since you never know when someone might drop the unit.
I'm a little paranoid about hard drive failures and I wanted to see if anyone had any thoughts about this. I ran SMARTCTL on my hitachi HD (laptop) and it's reporting my load cycle count as 183876, which is high but the drive is almost 3 years old now. My question is, I hear a clicking as I sit here on my computer every 4 seconds or so, pretty regular, and I notice that everytime I hear this click (its a very soft click, doesn't sound destructive or anything) I notice that the load cycle count goes up by 1. So I'm assuming I'm hearing the drive return the read head to its resting state, my question is... why does it do it every 4 seconds or so. It doesn't do it while I'm doing heavy hd work, only when I'm browsing the web or running smartctl. Is this normal behavior?
