annoying vibrations w/ latest unibody MBP15
I also want to buy a CTO MBP15 7200RPM 500GB, but all the different stories/problems and what a friend recently experienced made me hesitating in how to proceed w/ my order.
1. problem HDD freezes:
having crawled through different forums/websites, there seems a problem in case the MBP comes w/ the Seagate Momentus model having its own sudden motion sensor, which interferes w/ Apple's builtin sensor. Videos on Youtube show sporadical and very noticeable shorttime freezes while playing ego shooters for example. This problem might be solved if Apple is not using anymore the HDDs w/ own motion sensor (Seagate provides several models if I am right). Anybody has an update on this issue?
2. click sounds:
some people reported about clicking noises/sounds HDD are doing. This has been (successfully?) tackled by Apple in releasing a/some patches?! Not sure which HDD models are affected by this issue, but I have noticed that kind of problem was reported while googling around.
3. vibrations:
While the other 2 points might have solved (other HDD models, software patch - can someone confirm these?), this point is the most annoying one.
I was quite confused reading different comments, so some do not notice vibrations, other do but not annoyingly, and again other do notice it and say it's very annoying.
From what I understand so far, the vibrations are extremely annoying if you have the latest unibody MBP15 (the one since summer 09, w/ cardreader slot) and have it configured to 500GB 7200RPM drive via Apple.
The following story is almost assuming that the latest unibody design seem to do a very bad job on absorbing vibrations to a reasonable extent, revealed especially w/ 7200RPM drives.

So taking into account that people have reported different experiences with vibrations, in particular the latest unibody MBP15 as CTO w/ 500GB 7200RPM is subject to annyoing vibration issues.
As I have seen last week exactly such a CTO model a friend has ordered and received last week from Apple (CTO assembled/delivered from the Netherlands, where almost all European orders are handled), I can confirm at least this experience from my side.
The vibration is not slightly noticable, it is - as described from the other guy in the article (see link above) - really terrible. Absolutely not usable, if you are going to use the builtin keyboard and therefore need to put your hand on the MBP. I know it's hard to explain how it vibrates in words, trying to find something comparable you might can better follow:
take an old class model of an electrical shaver w/o any kind of cushioning in order to reduce the vibrations to the holding part, and imagine the vibrations there. This regards only to the vibrations, not the noise of course.
It is something like that. As the guy on the other article (link) described, like a small massage.
He had a phone call w/ Apple, but they decline to exchange the HDD. The brief answer was, that it is "normal", that 7200RPM drives vibrate. While this fact is generally ok compared w/ 5400er drives, it looks like that vibrations do appear on a very different "annoying"-scale resp. do appear more heavily in some cases. He's now going to get another drive from a non-Apple IT store. We'll see how his experiences w/ 7200 drives in the latest unibody MBP15 wil continue. Did I mentioned that he also got (and paid) the 3Y Apple Care... well, nothing really worth as it looks like, if Apple is not willing to do anything for a 3day old MBP, which just got delivered.
btw: my friend took out the HDD and in his opinion something might be slightly wrong with the HDD, while "bending" (not really bending, but sort of, touching/etc, you get the idea) it, the noise/vibrations (he was not so clear on this) where different (in terms of "better") than as if it is running just like w/o putting hands on. So he thinks the "case" or whatever term is applicable of the HDD itself is not quite straightly produced. So this leads to an idea of faulty produced HDD, which maybe affects a complete production series and/or appears in slightly different "production failures", which could explain the different experiences people made so far.
Personally I hope this is the cause, rather than the conceptional issue of the new unibody and being not capable of absorbing vibrations to that extent the older models can do.
But after all, this is just guessing. And it's annoying not to get an official statement by Apple, since they are the only ones who could enlight us. Due to sales, they barely would do it of course.
So what do I do now w/ my intention of a CTO MBP15 7200RPM 500GB?
Just order it, and if I unfortunately catch one of the "faulty" versions, try to get at least the HDD exchanged to a 5400er again at an Apple store and then buy on my own a 7200RPM 500GB-non-Seagate-drive elsewhere?
