Re: laptop harddrive Load_Cycle_Count issue
Generally Desktop drives don't have a need to park the heads as they are not vulnerable to bumps nor do they need to conserve power. So your desktop drives probably don't have a head parking feature. So I wouldn't worry about the desktop drive.
Also regarding the laptop 200,000 cycles doesn't seem too bad to me for a 2 year old drive. But it's hard to tell where those cycles come from because you have run so many different OS's on it. The main thing to watch with changing the hdparm -B values on a laptop is the temperature of the drive. So keep an eye on that and make sure it isn't exceeding the manufacturer's specs.
Also, one other thing to note. This problem with Load Cycle Counts affects ALL OS's. It has been documented numerous times on this forum and on several other places. Yes even Windows.
