希捷F3架構(gòu)硬盤的常見問題之一是編譯器問題。
One of the often problems on Seagate F3 architecture drives is a Translator problem.
通常我們會自動重新生成編譯器（通過Translator regeneration和Recovery translator程序）。
Usually?we try to regenerate Translator automatically (by Translator regeneration and Recovery translator procedures).
基本上可以成功解決問題并獲得整個用戶扇區(qū)的訪問，但有時候?qū)嵱贸绦驘o法正確隱藏NRG列表的缺陷，因此我們可以訪問用戶區(qū)域（從LBA0到中間的某個扇區(qū)） 。
Basically case?can be solved successfully and get an access to whole user area, but sometimes utility can’t hide a defects in to NRG-list properly as result we have a particualar access to the user area (from LBA0 till someone in the middle).

在本文中，我們想講述如何手動隱藏缺陷，重新生成編譯器以完成此硬盤數(shù)據(jù)恢復(fù)工作并獲得對整個數(shù)據(jù)扇區(qū)的訪問。
In this article we would like to describe how to hide defects manually, regenerate a translator and get an access to whole user area.

提供的步驟很困難，需要注意和重視。
Provided steps are difficult and require attention and сoncentration.

為了更清楚地說明，我們描述了真實情況下的所有步驟。
To make it more clear we describe all steps on the real case.
這是一塊Sentosa家族的ST1000LM010驅(qū)動器，但提供的步驟可以應(yīng)用于所有F3架構(gòu)希捷硬盤數(shù)據(jù)恢復(fù)。
It’s Sentosa family ST1000LM010 drive, but provided steps can be applied for all Seagate F3 architecture drives.

首先做一個翻譯器（28 sys文件），SMP標(biāo)志（93 sys文件），P-list（1B sys文件）和非駐留G列表（35 sys文件）的備份。
First of all make a backup of Translator (28 sys file), SMP flags (93 sys file), P-list (1B sys file) and Non-resident G-list (35 sys file).

這是非常重要的，他可以還原硬盤原來的狀態(tài)
It’s very important and allow to return back original state of drive if you try to perform steps without good result and now you need technical support department help.

檢查系統(tǒng)磁頭（0和1）是否具有寫入可能性。打開181（對于Head0）和182（對于Head1）sys文件，鍵入文本，寫入并嘗試重新讀取這些sys文件。
Check that system Heads (0 and 1) have a writing possibility. Open 181 (for Head0) and 182 (for Head1) sys files, type something text, write and try to re-read these sys files.

然后關(guān)閉93系統(tǒng)文件中除頂部之外的所有SMP標(biāo)記選擇，并將此更改寫入驅(qū)動器：
Then switch off all SMP flags ticks in 93 sys file except the top one and write this changes into the drive:

自動編譯器再生程序后，我們可以訪問第一個約450,000 000 LBA（所有其他扇區(qū)顯示錯誤，無法打開）。
After automatically Translator regenearation procedure we get an access to first approx. 450 000 000 LBAs (all other sectors show an error and can’t be opened).

我們需要找到最后一個可用扇區(qū)（我們可以讀?。┖妥詈笠粋€可用扇區(qū)（顯示“UNC”錯誤）。
We need to find last available sector (which we can read) and the last unavailable sector (which show “UNC” error).
那么需要了解一下它是真正的缺陷還是壞塊。
Then need to understand if it’s it a real defect or just a bad block.
具有壞塊的扇區(qū)具有唯一的ID，但缺陷沒有。結(jié)果這些扇區(qū)在終端報告中有不同的錯誤代碼。
Sector with the Bad block has an unique ID, but defect doesn’t have it. As result these sectors have a different error code in terminal report.

• Sence code = ****** 82 – 扇區(qū)問題，這意味著翻譯問題
  Sence code = ******82 – problem sector which mean a Translation issue
• Sence code = ****** 81 – 未校正的錯誤（基本上是壞塊）
  Sence code = ******81 – uncorrected error (basically it’s Bad block)

從上一個可用扇區(qū)之一啟動轉(zhuǎn)換器恢復(fù)過程。
Launch a Translator recovery procedure from one of last available sectors.
在這種情況下，我們從450,000 000 LBA開始：
In this case we started from 450 000 000 LBA:

而等待恢復(fù)過程在其中一個扇區(qū)被停止（對于希捷實用程序，很難“理解”它是否是壞塊或缺陷，并且在這個地方有多少）。
And wait while recovery process is freezed on one of the sectors (for Seagate utility it’s difficult to ‘understand’ whether is it a bad blocks or defects and how many of them at this place).
在我們這個例子中，
In our case it’s somewhere here:

停止恢復(fù)過程，并嘗試了解為什么實用程序無法通過此區(qū)域。
Stop the Recovering process and try to understand why utility can’t to pass this area.
轉(zhuǎn)到“扇區(qū)編輯”并嘗試打開這個問題扇區(qū)。
Go to “Sector edit” and try to open this problem sectors.
找到最后一個可讀扇區(qū)，然后找到第一個不可訪問的扇區(qū)。
Find a last readable sector and first unaccessable one.
這里是LBA 473 947 663 – 最后一次訪問，但填充“00”模式 和LBA 473 947 664 – 第一不可訪問（顯示“UNC”錯誤）。
Here is LBA 473 947 663 – last accesable but filled by “00” pattern
and LBA 473 947 664 – first unaccessable (show “UNC” error in registers tab).

那么我們需要了解在這個問題扇區(qū)之前有多少個扇區(qū)被“00”填補(bǔ)。
Then we?need to understand how many?sectors are filled by “00” before this problem sector.
在“扇區(qū)編輯”中，我們逐行回退，并嘗試找到具有數(shù)據(jù)的扇區(qū)。
In the “Sector Edit” we step back sector by sector and try to find a sector with data.

這里是有數(shù)據(jù)的扇區(qū)?– LBA 473 947 623。?
Here is sector with data –?LBA 473 947 623.

計算： 473 947 663 – 473 947 623 = 40扇區(qū)與“00”模式。
Calculations: 473 947 663 – 473 947 623 = 40 sectors with “00” pattern.

我們得到了一些“00”模式的扇區(qū)。
We get a number of sectors with “00” pattern.
因此，我們可以假設(shè)我們的驅(qū)動器有一些扇區(qū)鏈作為缺陷，我們可以嘗試將其隱藏到Non-Resident G-list中。
As a result we can suppose that our drive have a few sectors chain as defect and we can try to hide it into Non-Resident G-list.

返回終端報告，并找到與第一個不可訪問扇區(qū)相關(guān)的錯誤消息（LBA 473 947 664）。
Return back to the terminal report and find an error message related to first unaccessable sector (LBA 473 947 664).
需要將此LBA（邏輯地址）轉(zhuǎn)換為CHS（物理地址），因為缺陷表使用物理地址信息。
Need to convert this LBA (logical address) to CHS (physical address) view, ’cause Defect tables work with physical addresses info.

通過Ctrl + Z獲取終端訪問。
Get a terminal access by Ctrl Z.
然后命令如：
Then command like:
F3 T>/aF0387,fbc0,,10

/a – 切換到終端級別“A”。
/a – switch on to the Terminal level “A”.
F – 將LBA轉(zhuǎn)換為CHS
F – command for convert LBA to CHS

0387,fbc0 – 有問題的扇區(qū)的十六進(jìn)制減去兩個LBA(從上圖可以看到）
0387,fbc0 – hex view of our problem sector minus two LBAs (just for getting fully image of situation).
,,10 –需要多少扇區(qū)
,,10 – how much sectors are show after needed.

因此，我們知道我們的LBA 473 947 664（HEX中的0387FBC2）具有03887D4B物理地址（CHS）。
As a result we know that our LBA 473 947 664 (0387FBC2 in HEX) have 03887D4B physical address (CHS).

在驅(qū)動器ID窗口中，我們可以看到，該驅(qū)動器具有4096字節(jié)的扇區(qū)大小（每1個邏輯扇區(qū)8個物理扇區(qū)）。
In the Drive ID window we can see that this drive has a 4096 bytes a sector size (8 physical sectors per 1 logical sector).

因此，我們40個具有“00”模式的扇區(qū)被表示為5個邏輯扇區(qū)（5個缺陷）。
As a result our 40 sectors with “00” pattern are represented as 5 logical sectors (5 defects).

Open Non-Resident G-list editor:

添加新缺陷：
Add new defect:

并鍵入以下值：
and type following values:

Initial LBA –具有“00”模式的第一個扇區(qū)
Initial LBA – first sector with “00” pattern
Final LBA – 將自動計算
Final LBA – will be calculated automatically
Size – 多少扇區(qū)是缺陷
Size – how many sectors are defect
Flag – 設(shè)置0x20值 – 因此您的缺陷不會被驅(qū)動器本身和轉(zhuǎn)換器再生選項清理。
Flag – set 0x20 value – as a result your defects will not be?cleaned by the drive itself and Translator regeneration options.

在我們的情況下是：
in our case it’s:

將具有新缺陷的缺陷表寫入HDD（option “Save to Non Resident G-list”）
Write this Defect table with new defect into HDD (option “Save to Non Resident G-list”):

并通過終端命令或?qū)嵱贸绦虿藛沃匦律删幾g器：
And regenerate Translator by terminal command or by utility menu:

之后檢查扇區(qū)訪問。
After that check sectors access.

如果驅(qū)動器允許成功讀取相同或更少數(shù)量的扇區(qū)，則意味著您隱藏錯誤的缺陷。
If the drive allows to read successfully the same or less number of sectors it means that you hid a wrong defect.
檢查您的缺陷記錄的設(shè)置（第一個LBA和扇區(qū)數(shù)）或刪除此記錄。
Check the settings of your defect record (first LBA and number of sectors) or delete this record.

好的結(jié)果是可能訪問更多的扇區(qū)，這意味著你隱藏了正確的缺陷。
The good result is to get an access to more sectors than before – it means that you hide a correct defect.

現(xiàn)在我們可以訪問到大約475 000 000 LBA：
Now we get an access till approx 475 000 000 LBAs:

然后我們隱藏了一個正確的缺陷，可以繼續(xù)。
Then we hidden a correct defect and can proceed.

步驟是一樣的：
Steps are the same:
找到第一個不可訪問的LBA，逐行退步，并計算出多少物理LBA是不可訪問的。
find a first unaccessable LBA, step back sector by sector and calculate how many physical LBAs are unaccessable.
然后在Non-resident G-list中添加新缺陷，保存并重新生成翻譯器。
Then add new defect in to Non-resident G-list, save it and regenerate a translator.

最終的缺陷數(shù)量取決于硬盤，所以要有耐心。
Final number of defects depends on drive, so be a patient.

我們的案例有2個缺陷記錄，最后我們可以訪問整個用戶區(qū)域。
Our case has 2 defect records and finally we got an access to the whole user area.
