今天我们有一个奇怪的案例，这是一个关于日立IBM ARM HTS725050A9A364不能完整访问用户区的故障。
Today we have a rather unusual case to guide you through. It is about Hitachi IBM ARM HTS725050A9A364 without a full User Area access.
硬盘可以以读取完整ID，但无法访问特定LBA的扇区。
The drive starts with the full ID, but it has no access to sectors from the certain LBA.
首先，我们检查是否所有重要的模块已经上传到NV-RAM中。要做到这一点，我们点击工具 – >实用程序扩展 – >服务信息对象：
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以检查PSHT是否已加载到RAM中。让我们以PSHT为例做一下。
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.
正如我们所看到的，PSHT已经成功加载到NV-RAM中。这意味着驱动器的FW会正确初始化驱动器，因此我们应该在其他位置搜索问题。
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.
抱歉，只有对本文发表过评论才能阅读隐藏内容。
重新启动驱动器以重新初始化驱动器，并检查扇区访问：
repower the drive to reinitialize it, and check the sector access:
最后，我们可以访问用户数据！
Finally we’ve got an access to the user data!
当然，这是一个特殊情况，解决方案可能与我们下面描述的不同。一切都取决于环境和你要处理的硬盘故障
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.
