This programme disables APM on HDD (which on some models is cause of clicking and excessive increase of "Load Cycle Count" S.M.A.R.T. parameter).

Structures and disable APM part are ripped off from quietHDD programme.

Any similarity with https://sites.google.com/site/disablehddapm/ ?

Yes, that's the reason why I thought about writing a small one, since I needed only one parameter.

I´ve been wanting to do something like this for some time. I´m also suffering from this problem and the clicking noise most of the time is really loud, very hard to not listen. Currently I´m firing a program and manually disabling APM each time I turn on my notebook (which I use it as my desktop PC on a daily basis).

Thanks for sharing.

Yep, me also. Have to launch it every PC wake up - from hibernation or sleep also. Why don't they patch their firmware, I wonder? Mine is Hitachi HTS545050A7E

It's really a pity that this has become necessary. Disk head parking used to be a good idea, since HDDs would often be idle for very long periods of time. Parking the heads would reduce power usage, so the temperature wouldn't get as high and it would actually extend the life of the drive. But this feature's been ruined by idiot programmers who think it's acceptable for a program to write to disk every 10 seconds for no reason... Sad

What do you mean no good reason? Is it not necessary to write all your logs to disk so that the TLAs can come along later and see what you have been up to?

Mine is WDC WD6400BPVT-55HXZT2.

In the case of my computer, the HDD led turns on every second, and yet it insist in parking the heads moving them very aggressively (in fact I think the click sound is a bit louder than when I turn the computer off). I guess this is probably caused by the HDD internal buffer that doesn't cause R/W head activity soon enough to not timeout the idle timer.

At the rate the load/unload cycles occur, in my case it would exceed the manufacturer count limit in less than 3 years (and the warranty is 2 years, so forgive if I think they do this on purpose).

Fixed and updated source - now it works in GUI mode, and utilizes UAC (via manifest). Also, I'm not sure if old version disabled APM, since one parameter ([inbuffer.TimeOutValue]) was 0, but should be 1

I made it live in tray and keep an eye on Load Cycle Count parameter, and when it increases, it shoots the disabler, so even after a hibernation or sleep, it will be on-guard.
