Lacie D2 Extreme Hard Drive Options

[camarao]

I've just bought this Lacie D2 Extreme 250gb and I find it noisy or perhaps it's not in good conditions.
It is connected to the PC via USB 1. ( I will connect it to a Powerbook next week )
I can hear a kind of fan ( or maybe is the drive rotating. Is it suposed to be always rotating ? )which makes an high pitch noise .
And I can hear some strange noises like some metal thing is scratching the case. This happens sometimes (as an example,this happens when I select all the folders in the drive and then right-click in properties ) . Is this normal ? Everywhere I read it says this drive is silent but mine is not.

Note that what you hear depends of the model of drive used inside, and LaCie doesn't build drives, they integrate into their enclosures. I'm not using LaCie for years (too expensive) and build my own drives, right now i have 5 Icecubes pleiades enclosures with cheap drives in them (all crappy Maxtor, use Seagate instead).

I've just noticed that my Lacie D2 Extreme Triple Interface 250 gb external hard drive has a Maxtor drive inside. I've heard that Maxtor drives are noisier than other brands such as Seagate. Do you think this is the problem ? Do Lacie D2 have all the same Maxtor drives inside ? Maybe it's better to return this drive and search for another model ... Any sugestions ? It has to be fanless, 7200 rpm and firewire 800.

Or can you advise me on a good firewire 800 enclosure without fans and a good, fast and silent hard drive ?

Thank you
