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?
