Hi everyone. I am running the Jas.Intel.AMD.SSE2/3 10.4.8
I installed the OS X on the first partition

However, I found a problem: the hard disk works very noisily. I also installed FreeBSD, Windows XP , Windows Vista, SUSE linux on my PC. The hard disk works very quietly under all of these systems except the OS X.
Someone informs me that maybe the S.M.A.R.T hasn't been enabled on the OS X.
However, I went to the system profiler, the S.M.A.R.T function is veryfied.

My hard disk is WestData 250GB IDE. My motherboard is NForce 4 .

Does anyone here know the reason? Thank you in advanced.

Could you please "discribe" the noise a bit?

Why not post an MP3 File of the noise with OSX and Other os for comparison?

Western Digital 250G model :WDC WD2500JB-00REA0 tend to vibrate more than others. Try to secure it better in the bay ..

Samsung has announced 80GB and 160GB flavours of its new 3.5” SpinPoint S166 Series of ultra silent and high-speed hard disk drives. The S166 Series has a spindle speed of 7,200RPM, provides an 8MB buffer, features the SATA 3.0Gbps interface (PATA interface also available) and includes Native Command Queuing. The new SpinPoint S Series of hard drives offer upgraded versions of Samsung’s proprietary SilentSeek and NoiseGuard technologies. Benchmarking results presented by Samsung show competing hard drives generate on average 2.8 bel (1 bel = 10 decibels) in idle mode and 3.2 bel in seek mode, while Samsung’s S166 series generate just 2.4 bel and 2.75 bel respectively. Samsung claims the 15% noise-level reduction is “significant”.

“Samsung is constantly pushing the technology envelope with the introduction of new and innovative products that meet the computing needs of today’s most demanding customers and operating environments. This latest technology development by Samsung in the new SpinPoint S166 Series makes our high-end, award-winning hard drive products attractive to a wider audience by even further reducing acoustic noise and improving disk data transfer speed,” states TJ Lee, vice president of sales & marketing at Samsung Electronics’ Storage System Division.

I have the same problem... its not noisy mounting. My SMART is not enabled and my HD is running full speed all the time. That is the "noise". Any ideas???? I am noob with mac and unix
Thanx

How much RAM do you guys have? The only thing I could think up of why the disks are "thrashing" about under OS X is virtual memory swapping. Regarding SMART, it should be properly detected, well at least they all work fine on mine (6 HDDs under OS X).

Dunno if it helps, but it's an idea.

I have a gig. I'm @ a loss about the SMART

This has to be one of the funniest threads I've read in awhile. I don't think I've ever encountered this problem. I mean, I don't care about the noise - so I'd never have noticed any of this. The first thing I usually do with things is turn off all power management set everything to "full performance." =)

Is it a whine or is it clicking a lot?
