From: Stan Blazejewski on 17 Jan 2006 23:02 I'd have to side with Odie here. About 15 'years' ago I pulled apart an (now) old 85meg RLL hard drive because the auto park wouldn't release. This was on the kitchen table & that drive is still working today .... you'd think it would have just plain worn out by now. I noticed it had filters inside it to clean the air moving inside it so I expect it was all clean again within seconds if not minutes of firing up again. The 'new' drives I've pulled apart for the magnets seem to have the air filters as well although I'd expect today's technology to be less tolerant to dirty air what with the amount of data that they pack into the smaller space but I still wouldn't expect it to die in "a few days or weeks".

Take apart any 3.5" hard drive and pull the magnets out, they'll stick to each other very strongly. If you can find an old 5.25" SCSI drive you'll likely find even bigger magnets.

Examine that filter carefully and you will find that its primary function is to filter the tiny amount of air moving through the pressure-equalization hole and that there is no mechanism by which all or any significant portion of the air circulating inside the capsule can be made to pass through it. > The 'new' drives I've pulled apart for the magnets seem to have the air > filters as well although I'd expect today's technology to be less tolerant > to dirty air what with the amount of data that they pack into the smaller > space but I still wouldn't expect it to die in "a few days or weeks". It dies as soon as something hard enough to scratch the platter or head and small enough to get wedged between them finds its way into that space. In the real world people have tried this, and the drives typically died in anywhere from a few hours to a few weeks. > On Mon, 16 Jan 2006 13:48:28 -0000, "David C.
