...and it's gone again

From: Ian McCall on 26 Sep 2006 16:08 My 'resurrected' disk lasted less than two days then. This time I'm trying to start up in verbose mode. It gets as far as reporting IOBlueToothPCIController, then dies. I get the following message: disks0s2: 0xe0030005 (UNDEFINED) Load of /sbin/launchd, errno 5, trying /sbin/mach_init disks0s2: 0xe0030005 (UNDEFINED) Load of /sbin/machinit failed, errno 5 A quick search around shows that others have seen this 0xe0030005 message, and it's always been a dead disk. <http://www.google.co.uk/search?hl=en&q=disk0s2+0xe0030005&btnG=Search&meta=> I'm utterly speechless. I can't live with this kind of unreliability - once again the machine was boiling hot. It's a design flaw, and I'm going to start talking about refunds tomorrow. I am less than hair's breadth away from simply asking for the money back and then going off to buy a ThinkPad with Ubuntu on it. Cheers (sort of), Ian

The vast majority of machines ship without active cooling to the hard drives. Laptop drives aren't as susceptible to heat failure as their desktop counterparts, but what with the additional heat generated by modern laptops (dual processors, especially) there are bound to be problems. I am ever thankful that I have never been in a position to need a laptop. If I did have to use one, it would be kept in a concrete bunker overnight... I certainly wouldn't touch the latest generation Apple laptops. Anything that gets uncomfortably hot on the outside is going to be scarily hot internally.

I know you have a bee in your bonnet about cooling, but that is just plainly not true. First of all, these companies - whose billion-dollar existences depend upon their being able to sell machines which don't hit the market with design flaws that over-cook their delicate innards - know quite well that they are always a design-flaw away from going down the pan humiliatingly. They consider cooling just as carefully as they consider everything else, from the exploding batteries to leaking capacitors. As those examples show, for one reason or another things don't always work out, but to imagine that they don't consider as many such issues as they have had the opportunity to be aware of is absurd. Secondly, we know quite well that in Apple's case in particular the question of cooling is and has always been a real issue. Apple famously purchased a Cray X-MP in the 1980s; one of its first jobs was to model airflow in the cases of the new Mac II machine (equally famously, it turned out that Cray were using Macs to design their computers). With the 2nd-generation iMacs and the Cube, Apple demonstrated that their thinking about cooling was as inventive and central to their projects as anything else. The PowerMac G5s and the iMac G5s, just in the complexity of their cooling systems, make it quite clear that it's an issue of prime importance. Daniele

Sorry, but I really have to disagree. Comparing a PowerMac G5 tower with a MacBook Pro is not a fair comparison. One is a large tower with plenty of room for cooling and airflow, the other is not. Just because Apple have designed decent cooling in one of their systems does not mean they're going to that across their entire range of products. If (and I say if, because I don't own a MacBook Pro so I'm not speaking from first-hand experience) MacBook Pros really are getting so hot that hard drives are failing, then that is a serious issue. Full stop. I have personally seen this happen in a Dell Inspiron 1100 where the CPU was getting to about 70C and the hard drive to about 64C. Turned out the CPU's heatsink and fan needed a good clean and some decent heatsink paste, which brought both temperatures down to the 50ies. But, overheating in Dells is a known issue, hence applications such as i8kfangui. Dave -- (remove spamblock or reply to group)
