今天我們有一個奇怪的案例，這是一個關于日立IBM ARM HTS725050A9A364不能完整訪問用戶區(qū)的故障。
Today we have a rather unusual case to guide you through. It is about Hitachi IBM ARM HTS725050A9A364 without a full User Area access.

硬盤可以以讀取完整ID，但無法訪問特定LBA的扇區(qū)。
The drive starts with the full ID, but it has no access to sectors from the certain LBA.

首先，我們檢查是否所有重要的模塊已經(jīng)上傳到NV-RAM中。要做到這一點，我們點擊工具 – >實用程序擴展 – >服務信息對象：
First of all, we check whether all important modules have been uploaded into the NV-RAM. To do that we go to Tools->Utility extensions->Service information objects:

并到RAM / NV-RAM以檢查PSHT是否已加載到RAM中。讓我們以PSHT為例做一下。
and to RAM/NV-RAM tab to check whether the PSHT have been loaded into the RAM. Let’s do it using the PSHT as an example.

正如我們所看到的，PSHT已經(jīng)成功加載到NV-RAM中。這意味著驅(qū)動器的FW會正確初始化驅(qū)動器，因此我們應該在其他位置搜索問題。
As we can see, the PSHT has been successfully loaded into the NV-RAM. It means that the drive’s FW initializes the drive correctly, so we should search an issue somewhere else.

檢查P-List以查找內(nèi)部的任何缺陷：
Checking the P-List in order to find any defects inside:

缺陷列表有完整的缺陷條目，但我們不知道它們是否真實。
Defect-list is full of defects, but we don’t know if they are real or not. Previously the drive owner consulted another data recovery engineer, so the device might be ?intentionally spoiled.

我們來比較PSHT?copy0和factory copy：
Let’s compare the PSHT copy 0 with the factory one:

差異是巨大的，但兩個PSHT副本看起來不錯。
The difference is huge, but both PSHT copies look good.

我們現(xiàn)在能做什么？由于我們做了完整備份，因此知道磁頭是健康的并且可以寫入服務區(qū)，讓我們嘗試一下：將PSHT factory copy寫入SA中的copy0。
What can we do now? Since we did a full backup, know that heads are healthy and can write in the Service Area, let’s try one trick: write the PSHT factory copy into the copy 0 in the SA.

Least said, soonest mended. Write the PSHT factory copy to the copy 0:

并保存更改
and save the changes

重新啟動驅(qū)動器以重新初始化驅(qū)動器，并檢查扇區(qū)訪問：
repower the drive to reinitialize it, and check the sector access:

最后，我們可以訪問用戶數(shù)據(jù)！
Finally we’ve got an access to the user data!

當然，這是一個特殊情況，解決方案可能與我們下面描述的不同。一切都取決于環(huán)境和你要處理的硬盤故障
Of course, it’s a particular case and the solution may differ from the one we describe below. Everything depends on circumstances and the drive you’re going to deal with.
