Western Digital Scorpio Blue 640 Drive draws too much power in a MacBookPro

I just received a Western Digital 640 gb (WD6400BEVT) Scorpio Blue Drive for my MacBookPro. I've noticed that the drives "Throttles" a lot, i.e. seems to accelerate/spin and slow down/stop in a way I've never seen in any other drive, and I've been through lots. It wouldn't be a problem if the computer didn't seem to be sluggish in response, much more sluggish than with the 200G Hitachi drive I had before. I will sometimes start typing something and the computer will be slow to react; I also see the spinning ball much more often.
I contacted WD and was told that "It is quite possible that the computer cannot manage the capacity and energy demand of this drive. If the previous drive was under 250 GB, a 640 GB drive will encounter these issues."
I'd never hear of this problem, and I'm really confused since the new drive has a lower rated energy requirement (it's a 5400 rpm vs 7200) than the previous drive. Has anyone else had these problems? Can someone tell me whether this is reality or obfuscation on the part of Western Digital?

Ok - just for anyone who is still monitoring this thread or who comes here with spin down and clicking issues like I did - I did a check on my recently installed Hitachi 5K500.B 500mb 5400rpm HDD last night (well early this morning!) and found 5700 load cycles - that is after about a week's use!!! After exhausting my free goes with SMART Utility I downloaded smrtctl and eventually figured out that it gives you a little icon on the menu bar that if you click it tells you all about your HDD smart details (amazingly simple and stunningly good value being free!!! But dear lord wouldn't it be great if these things came with user hints a mere mortal could understand!!) - anyway by then my load cycles were up to 6054!!!. I could hear the **** drive getting quieter and quieter then up it would spin again - have to say you need to be quiet to hear this with the little Hitachi drive - not like the WD, it's wooshing was easy to detect.

Anyway, after another hour trying to understand various conflicting installation instructions I eventually got HDAPM up and running and since then my load cycles have been, wait for it, 1! And that was when I sent my Macbook to sleep last night I suppose!

So, the upshot is... just because your drive isn't lagging desperately with the beach ball displaying all the time, doesn't mean it is behaving properly in your Macbook. These new SMART drives don't like Macbooks, or Macbooks don't like these new drives - whatever, waiting for Apple to sort it out will take for ever because your basic Mac users on the whole are not the sort to go swapping HDD about (all present company excepted of course!) - if I had left this untouched I would have had nearly 315,000 load cycles by the end of one year... depends on the drive of course but from what I read here and elsewhere not a sensible situation - in fact I think smrtctl is reporting my drive is already in "old_age" poor thing!

Hope this helps anyone who like me thought the Hitachi would just work straight out of the box - would that computing life was so simple 🙂

This really is too much. I can't believe that I can't just by a replacement drive that will work. I thought that the Hitachi drive would be the answer, but apparently not.

It just shouldn't be this hard. I switched to Mac in late 2008, but as soon as I can afford a replacement I will be moving back to Windows. While Windows 7 may not be as polished as OSX, I have never run into problems like this.

In addition to this problem the upgrade to 10.6.3 broke my Samsung CLP-310 printer (along with everyone else with this printer and the CLP-315)- and this wasn't fixed in 10.6.4. This is despite these printers being listed as official Apple supported printers.

I have just had enough.

Hi there - I finally settled on these instructions at:

http://mymacfixes.blogspot.com/2009/06/how-do-i-stop-clicking-noise-from-hard.ht ml

seems like a step-by-step but some knowledge of what you are doing is presumed (as per usual). I didn't get anywhere with the hdapm link on these instructions as it downloaded as a "package" which I then auto installed, only to find I just ended up with a daemon but with all the wrong settings in it -which took a while for me to get rid of! I eventually went here and downloaded this one:

http://mckinlay.net.nz/files/hdapm.dmg

you can tell it's the right one as when you have downloaded it and clicked to mount, the .dmg you will see in Finder contains a little file called hdapm, plus hdapm.plist plus a read me text file (not a package) - it's this hdapm file you copy to where the instructions say.

You will need this (as it says in the instructions):

http://sourceforge.net/projects/lingon/files/Lingon/2.1.1/Lingon-2.1.1.zip/downl oad

and when it briefly says "With Lingon, create a new launchd configuration file" it just means you press the "plus" button on the menu bar for a "New" whatever the **** a "launchd" is! Then just follow the instructions as they will make sense when you are in Lingon doing it. As he says you can see what your user name is (for where you type "com.yourusername.launchd.hdapm" and replace the yourusername bit) as it is displayed in Finder on your Mac next to the little house symbol in the sidebar.

Best of luck - don't do it at 1am like I did, although I must say I slept well after a successful install 🙂

PS. all the bits about "authenticate" really through me, where? how? when actually all he meant was you will get asked for your Mac password at some stage so type it in to proceed!
