※ 引述《middleman ()》之銘言:
: 今天剛買了日立2T的硬碟,拆封之後發現正面有一個小孔
: 硬碟上面的貼紙還特地註明不能蓋住那個孔,想請教一下各位這個小孔是做什麼用的啊?
: 因為目前所用機殼的設計及剩下的的空間,可能會讓硬碟裝上去後蓋到那個小孔
: 不知道對硬碟會有什麼影響? 希望各位能幫忙解答一下
: 謝謝
觀念1:硬碟內部是常壓狀態,非真空狀態.
觀念2:要維持不同溫度的常壓,就必須要跟外部的空氣有調節平衡的孔洞.
觀念3:硬碟內部屬高精密度零組件,為了磁碟/磁頭運轉,必須維持在非常
潔淨的狀態.
因此,基於上述觀念,那個洞就是跟外部空氣進行交換的所在,且在洞內側
裝有極微細孔隙的過濾小筒(拆壞硬碟就會看到了),
以過濾並預防空氣內的微粒造成硬碟內部的損害.
總之,若上面要疊東西,那個孔隙別用貼紙之類物品貼住,至少要留一點
小縫隙.
