問題

超級使用者讀者L.B.想知道在拆卸舊硬碟之前，他應該擔心的舊硬碟中是否有有害物質：

I have an old laptop at my disposal that has a malfunctioning hard-drive in it. I would really enjoy taking the drive apart and looking at it. However, I would like to ensure that I am not going to end up with lead poisoning or any thing like that.

So, my question is, are there any health hazards associated with the contents of an internal hard-drive (that was placed in a computer manufactured in 2004)? I am not worried about doing damage to the hard drive or the computer, just me!

L.B.有沒有什麼危險品需要擔心，或者他能繼續把他的舊硬碟拆開嗎？

答案

超級使用者貢獻者Tonny和Ex Umbris為我們提供了答案。首先，託尼：

No problem.

There could be a **all amount of lead in the solder (if the soldering dates from before ROHS compliancy), but it is locked up in the material. It will not escape unless you take a Dremel or drill to the printed circuit board, or heat it in any way.

And even then, the amount is so tiny. You will end up with far more lead from air-pollution by car-exhausts if you live near a highway or in a city. Same goes for chemicals in the PCB and/or electrical components. As long as you do not cut or drill into them, it is no problem at all.

People who assemble these things do not take any special precauti*** either. And they handle far more of them than you ever will.

然後是來自本影的答案：

The only “danger” I have ever encountered are the voice-coil permanent magnets. If you were to pinch some flesh between them, you could end up with a minor but painful hematoma or laceration.

When separated by a **all distance (3-4 mm), they can exert several kilograms of force, which increases quadratically as they get closer together. If you let them stick together, it will require significant force and a wedge of some kind to separate them.

I have a couple of dozen pairs in a desk drawer.
