Ok, here is a question for you guys. Yesterday i was lurking the Xtremesystems and found out, that there is some critical error about the WD Caviar Green disks, which makes them to park the head much more often than they should, therefore shorten their lifespan. OFC, i happen to have one, 2TB WD20EARS, but...

- i am not sure about the load cycles, the Intel Toolbox shows it made about 27500 cycles in 1797 hours (it is 9 months since i plugged the disk in, when i bought it), which on average means cca 18 cycles per hour....is this too much or its ok? People around the net with the problem claimed to have 60-100 writes per hour, so i suppose 18 is not that bad. I use my disk as a storage after all, i have 2 more SSDs for system and games. I have the Opera Cache and Temp directory on this HDD though. Funny thing is, while i found quite a lot info dedicated to the issue, there was no single source to state, what is (should be) the average amount of load cycles per hour for healthy drive. Internet is such a greatthing, but it hate, when i cant find answer for one simple question, thought there ia a gazillion of sources which talk the subject i am interested in.

- i downoladed the app called wdidle3, which was supposed to fix it, i managed to run it via DOSBOX, but it says no disks detected? WTF? What shoud i do now?

- if i did nothing and the disk failed in the future, is there a possibility to retrieve data? I mean, if it would fail cause of this, the reason would be wearing of the head, not the damage to plotters, so it should be possible, right? OFC it can fail today for completely other reason and i would lose my data, but in that case i can do nothing (bar making copy), so it is irrelevant.

Thanks for the answers

I don't think you can run wdidle3 from within Windows, it will need to be run from a DOS bootable USB stick or something like that.

27500 load cycles over 9 months isn't too bad, I've read about drives that racked them up a lot faster. Supposedly WD's consumer drives are rated for 300k load cycles, so you wouldn't have to worry about hitting this for quite a while. SilentPCReview has a pretty big thread on this topic, you might check it out.

I have a 1.5 TB WD Green drive. I put it into a new build and noticed a clicking noise coming from the drive. Checked the park cycles in HD Tune and it was some ungodly number... 95K I think. Anyway, I booted into FreeDOS, which you can make a USB with very easily using unetbootin, ran the wdidle3 program, and the noise and the park/unpark cycle increases stopped.

Thank you for answers....but it seems to be working via DOSBOX, it just cant detect the disk, but the application will start... well maybe it cant find the disk cause of the DOSBOX, i do not know, will check the links you provided to me... thank you all again

Quite obviously it is not working via DOSBOX seeing as how it can't find a disk. Windows will not allow that to happen. You must boot the system to DOS plain and simple.
