該程序適用于WD Marvell和WD Caviar 架構(gòu)的西數(shù)硬盤數(shù)據(jù)恢復(fù)過程。
The procedure is applicable both for WD Marvell and WD Caviar architecture drives.

當(dāng)我們恢復(fù)服務(wù)區(qū)模塊時(shí)，我們需要確保系統(tǒng)頭可以在SA中編寫模塊，而不會(huì)出現(xiàn)錯(cuò)誤。
When we recover Service Area modules we need to be sure that system heads are able to write modules in SA without errors.

在硬盤數(shù)據(jù)恢復(fù)過程中進(jìn)行任何更改之前，請務(wù)必備份ROM和SA模塊的所有重要模塊， 因?yàn)槲覀儚牟恢来蓬^停止工作的確切時(shí)刻。
Make sure that you have a backup of all important modules of ROM and SA modulesbefore making?any changes since we never know the exact moment when heads stop working.

您可以通過按“HDD resources backup”執(zhí)行所有資源的完整備份。
You can perform a full Backup of all resources by pressing “HDD resources backup”.

這是推薦的手動(dòng)檢查系統(tǒng)頭的方法。
Here is the recommended manual method to check system heads.

首先我們打開“Modules目錄”：
At first we open “Modules directory”:
Tools => Utility extensions => Modules directory

確保您通過ABA使用Copy 0
Make sure that you are working with Copy 0 via ABA

然后我們按關(guān)鍵性對模塊進(jìn)行排序，以方便導(dǎo)航
Then we sort modules by criticality for easier navigation

并選擇并打開SA中的任何不重要的模塊（例如“Log”Dr級模塊之一）。
And select and open any NOT important module in SA (for example one of “Log” Dr-grade modules).

如果模塊不可讀，可以嘗試另一個(gè)。
If the module is not readable you can try another one.

在模塊的主體中??輸入任何文本（例如“測試”字）
Type any text in the body of the module (for example “testing” word)

并按“Write data to HDD”按鈕
And press the “Write data to HDD” button

選擇要寫入的副本（復(fù)制0表示0頭，復(fù)制1表示0頭），現(xiàn)在我們要檢查兩個(gè)頭，以便我們檢查并確認(rèn)。
Select copies you want to write (Copy 0 means Head 0, Copy 1 means Head 1), now we want to check both heads so we check both and confirm.

等待驅(qū)動(dòng)器完成寫入，然后再次準(zhǔn)備就緒
Wait until the drive finishes writing and become Ready again

驅(qū)動(dòng)器再次就緒后，我們需要從硬盤重新讀取模塊以檢查結(jié)果。我們可以重新打開它，或者只需按面板上的“取消”按鈕（實(shí)際上重新讀?。?br /> After the drive is Ready again we need to reread the module from the surface to check the results. We can reopen it or just press “Cancel” button on the panel (it gives reread from surface command actually).

之后，我們可以有三種可能的情況：
And after that we can have three possible scenarios:
1.我們的測試字符是存在的（如我們所說的）。這意味著該模塊寫入是成功的，當(dāng)前的頭寫入沒有問題。我們可以使用這個(gè)頭修理SA。
1. Our test typing is present (as in our case). That means the module was written successfully and current head have no writing problems. We can continue repairing of SA by this head.

2.我們的測試打字在重讀后出現(xiàn)。這意味著頭不能寫。用這樣的頭重寫模塊是不可能的。
2. Our test typing diasappeared after rereading. That means head can’t write. It is impossible to rewrite modules with such head.

3.我們無法從新讀取模塊。這意味著頭寫錯(cuò)誤和損壞模塊。用這樣的頭重寫模塊是不可能的。
3. We can’t read the module from the surface. That means the head writes with errors and spoils modules. It is impossible to rewrite modules with such head.

現(xiàn)在我們知道頭0的狀態(tài)，我們可以切換到1頭.
Now we know the state of Head 0 and we can switch to Head 1.
我們按“Select data”按鈕
We press “Select data” button no the panel

并將“Copy to read”參數(shù)切換到“Copy 1”。按OK確認(rèn)。
And Switch “Copy to read” parameter to “Copy 1”. Confirm by pressing OK.

Here you will have the same variants of behaviour as with Head 0.
在這里，您將有與0頭相同的備份

在大多數(shù)情況下，我們需要修復(fù)SA的至少一個(gè)副本，然后編輯SA區(qū)域以阻止訪問損壞的SA。
所以經(jīng)過這個(gè)測試，你可以選擇修復(fù)的副本（頭必須能寫）。
In most cases we need to repair at least one copy of the SA and then edit SA regions to block access to the damaged one.
So after this test you can choose the copy to repair(the head must be able to write).
