現在,硬盤的容量越來越大,給我們的工作帶來了極大的方便.但是,硬盤的脆弱使得他一旦出現問題.我們又沒有及時備份,後果將是帶來無法估量的損失.幸好,目前在國內出現的一個新興行業"數據恢複",使得我們遇到數據丟失,病毒破壞,誤刪除,誤ghost,硬件故障...等不幸後可以極大地挽救重要數據,從而減少損失.
今天介紹的是大家最為關心,最為好奇,也很少見到的硬盤開盤更換磁頭處理.首先我們要了解一下磁頭與盤片的關係,大家都知道,數據是以磁記錄方式存儲在盤片上的,讀取和寫入都靠磁頭來完成.然而,磁頭並不是貼在盤片上讀取的,由於磁盤的高速旋轉,使得磁頭利用“溫徹斯特/Winchester”技術懸浮在盤片上.這使得硬盤磁頭在使用中幾乎是不磨損的,這使得數據存儲非常穩定,硬盤壽命也大大增長.但磁頭也是非常脆弱的,在硬盤工作狀態下,即使是再小的振動,都有可能使磁頭受到嚴重損壞.由於盤片是工作在無塵環境下,所以,我們在處理磁頭故障,也就是更換磁頭時,都必須在無塵室內完成,而且還要有紮實的基本功,熟練的技巧,才能使成功率大大提高上海數據恢複.
現在我們就來邊看圖片.邊了解更換磁頭的具體過程

首先,開盤需要特定的條件和工具,無塵環境是必不可少的,其次我們可以從圖中看到還需要醫用手套,美工刀,尖嘴鉗,直頭和彎頭鑷子,螺絲刀(一字和t8)
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" resized="true" />
這次我們要更換磁頭的硬盤是某客戶的一個邁拓120g 硬盤,故障情況是工作後不認盤,電機轉,有敲頭聲.首先,我們用美工刀小心地揭開硬盤上的保修標簽.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
接下來當然是拆除top上的所有螺絲,為了工作效率,外麵不是要求很高的螺絲,我們可以用電動起子去卸.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" resized="true" />
我們小心的將螺絲放在培養皿裏,打開top,我們就可以一覽無遺地看到硬盤的內部結構了,我們可以清楚地看到組成硬盤的各個組件,包括底座base,馬達moter,磁盤disc,磁頭eblk,和已經打開的頂蓋top......
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
打開盤腔以後,我們首先要拆除磁頭eblk與主板pcba的連接線.這裏,我們就不選用電動起子了,改用手工拆除,這樣可以大大地降低失誤而造成的嚴重後果,盤片是需要特別保護的,不允許有任何物體掉落在上麵.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
接下來我們來拆vcm組件中的釹磁鐵,釹磁鐵的吸力是非常大的,我們要非常當心,左手用力按住盤腔,右手緊握尖嘴鉗,將釹磁鐵取下.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
然後我們需要把磁頭從盤片上停靠區移出來,移出盤片,這樣才可以將磁頭拆下.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
我們用一字螺絲刀小心地拆下磁頭,用左手按住磁頭,避免磁頭碰到任何東西.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
小心翼翼地手拿vcm,把壞磁頭取下.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
這張圖上我們可以清楚的看到,這個120g的邁拓盤有3個磁頭,上麵兩個(並著),下麵一個獨立的.盤片數目是2片.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
取下磁頭以後,我們找出和壞磁頭同一型號的磁頭去更換,我們找來事先準備好,存放在培養皿裏的備用磁頭.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
小心地將其裝在盤腔上,尤其是磁頭不能碰到任何東西,因為磁頭是非常脆弱的,上麵的簧片稍微受到力就會變形,一旦磁頭變形,即宣告這個磁頭的報廢.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
接下來這個步驟是關鍵中的關鍵了,工程師的基本功和經驗都體現在這裏了,這裏失誤,將嚴重損壞新換上的磁頭,這個步驟就是磁頭上盤片,工程師用鑷子將磁頭挑開,直至3個磁頭全部放到盤片上,當然,磁頭數目越多也就意味著難度越大.
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
把磁頭移到盤片上的磁頭停靠區
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
把磁頭與pcba的連接線固定好
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
安裝vcm組件......
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" resized="true" />
ok,我們已經安裝好盤腔裏麵的所有東西了.仔細檢查一下就可以關上top了
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
最後一步.安裝top,上螺絲當然要注意順序,不要一次上緊,先對角上齊螺絲,然後在對角依次擰緊每個螺絲......
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}
}" border="0" />
嗬嗬,一切的努力終於換來了成果,接上pc檢測一下,順便用耳朵聽一下,硬盤已經可以正常認盤了,盤片沒有問題的話可以直接掛負盤直接複製數據,如果盤片有問題,我們就需要用軟件來跳過壞道恢複數據.......
