Lookie here (http://www.silent.se/bilder/harddisk_mechanics.wmv)

They die. It's just a matter of when.

[tesco]

how could they get a video of that? i heard that if just one piece of dust gets into a hard drive the head would crash and then teh whole disk would be ruined.

That drive is ruined, ROSSCO_2004.

I have seen a modded case that features a completely exposed HDD unit.

Turns out the guy was trying to put a window in the cover. Took every possible precaution, and, when finished, it actually worked...for about two weeks.

So, new drive...try again.
Same results.

Conclusion?
DON"T OPEN 'EM UP DUMMY!

But, as he had two brand new, non-functional drives, he decided to use one of them for show anyway.
It spins and the arm seeks, but the real (untouched) HDD is stealthed away out of sight.

I have seen the covers polished, too.
Mine seems to have a couple of breather(?) holes in it and I'm scared of getting junk in them....

thats a pretty kool idea, how does the hard drive keep spinning though if its got nothing to load...or does it just always spin when there is power.

Certain parts of the drive platter (where factory settings are stored) have to be accessible at spin-up, but as long as that bit is ok there's no reason why a "bad" drive should not appear to work.

Bear in mind that the disk is spinning at 4500rpm or more, so any small particles landing on the disk are likely to be thrown off. In all probability the air drag from the surface of the disk would stop a particle from actually touching the disk - that is how the disk heads used to work, they actually flew on that air cushion (maybe they still do, I'm not up to date on current disk technology)

The biggest danger time is when the drive is not spinning. Other than that you would have to be unlucky to get a particle between the head and the disk.

forget small particles, the hdds are vaccum, meaning no air

even if you let air in there the drive is ruined too <_<

that&#39;s why i have like a constant supply of hdds from my fav hardware shop....

:lol:

i get em free too <_<

No, hdd&#39;s don&#39;t work in a vacuum, they actually NEED air to operate otherwise the head hits the disk. But it is superclean air that&#39;s inside. And they have a very tiny breather to equalise the pressure, but filtered so no particles can get through.

Those breather holes have extremely fine filters behind them.

If you take an old (defective) drive apart you can see the filters.

The small white part in the air passage.

OK,
I had this video in which a guy demonstrated how a harddisk really works.He loaded the window through an opened harddisk and there is no problem at all. He sucessfully loaded the windows O.S In the end he said that the problem really comes as lynx mentioned before when the dust particle comes in between the cushion and the head. Well how it comes that depends on the way u ............ :D
