What I want to know is if the load cycles is a real concern or are we paranoid? I will run a test as I have the same drive. My drive clicks and it is always active, unlike the stock 750 GB Toshiba 5400 HDD. Also, I repaired disk permissions, as my boot up time decreased 3 fold since I installed the 750 GB WD.

EDIT: I am testing the battery life for the first time with the WD HDD. If I do not like this drive, then I will not hesitate to reinstall the stock HDD and use this drive as a scratch disk etc...

If your load cycles are increasing at a rate that is too high, then yes, it's something to worry about. With 300000 as the rated number, just do the math and figure out how long it would take to reach 300k. If it's more than 4-5 years, I'd just let it keep adding cycles since most people won't be using the same HDD for over 4 years anyway.

Thanks for the information Sir. I will check it out right now.
 
The HDD is great otherwise, can't feel vibrations, fast, etc, it's jsut I can hear the heads parking so much, I'm at like 79 load cycles/hour so it happens more than a minute average and that what kind of bothers me. Can't get hdapm to work on here and my ssd and HDD swap disk1 disk0 upon reboot sometimes lol, but yeah I I get failed hdapm max in terminal =(

I found another solution which is booting it into a windows machine via a usb drive in dos and a wdidle program and changing idle that way, so I'll have to do that when I have my work laptop to swap the drives out.
