Load cycle count of new hdd

Solution
Load Cycle Count is the number of times the head has been moved to the "parked" position. That typically happens when the drive is shut down or, in a laptop, it is powered down to save the battery.
I can't say if that is too many times or not. A lot depends on the exact model of drive you have and how you are using it. If you are mostly running from battery power there isn't much you can do about the LCC other than change the frequency that it powers down when not in use on battery power. The shorter the time the more cycles you will get.
But you can run from wall power whenever available and set up a profile for that where it doesn't power the drive down at all while on wall power. Running from wall power whenever available will also extend the life of your battery because it won't go through so many charge/discharge cycles.
It looks like you're running it about 15 hours a day. If a lot of that time is just sitting idle you might just power it down when you know you won't be using it for a while.
Specific models have different design criteria for Load Cycle Count. take a look at the following link and scroll down to the LCC.

And you might see if you can find more info for your specific model on the WD web site.

Several WD drives (not just the Green) are programmed to park their heads after an unusually short idle time (8 sec on the Green, I don't have personal experience with the Blue or Black but I hear they're affected too). WD says the drives can withstand being parked that frequently, but if it makes you nervous you can hack the firmware with the WDIDLE3 tool that WD released. Unfortunately they changed their website last month and the file isn't available anymore. But through the magic of the Internet Wayback Machine...

Further instructions on using the tool are here:

Note: I no longer recommend WD drives because of having to do silly workarounds like this. I had a swapfile on my WD green drive and it was causing the computer to freeze for about a second every 10-30 seconds, until I fixed it with WDIDLE3.

The head parking is separate from the platter spin-down. When I had the swapfile on the drive, if the heads were parked the screen would freeze in games for a bit less than a second while unparking. It would freeze for 3-4 seconds when spinning up the platters.
The platter spin-down time can be controlled within Windows' advanced power management options. The head parking timeout cannot. The WDIDLE3 program I linked allows you to change it.
I was about to try to wdidle3 on wd blue, but i used HDDscan, where i fast 3 times pressed Spin down and since then heads do not park-at least i dont hear them(even on stock settings)....i hear them only when i turn off pc/sleep.
So maybe i broke it with spinning it down? or hdparm did break it.
However, it looks like i got rid off of occasional lags in csgo and other games.
Im curious how long that hdd will last.
Edit: when i set APM from 1-250 i hear every few seconds voices like heads cant be parked, like scratching. and when i turn off APM disk is quiet and running nicely....so its broken?
