# HDD Security Configuration（硬盘安全配置）

本选项用于配置硬盘的安全保护功能，包括设置硬盘密码等。

此选项仅在检测到已连接硬盘时才会显示。此选项列出所有已连接的硬盘清单，并可针对选择的硬盘设定密码。若设置了 HDD 密码，启动设备或进入 BIOS 设置时，系统会要求输入 HDD 密码。只有在正确的密码输入后，硬盘才会解锁，允许设备正常启动或访问存储在硬盘上的数据。

注意：此硬盘锁会将密码直接写入硬盘的固件存储区域。即使将硬盘物理拆卸并连接到另一台计算机上，该硬盘也无法被正常识别与访问。

该功能适用于机械硬盘（HDD）和固态硬盘（SSD）两种存储介质，图中所示为固态硬盘。

HDD 密码说明：

可设置、修改和清除硬盘的用户密码和主密码。

用户密码是启用硬盘安全功能的前提条件。

如果已设置主密码（可选），也可用其解锁硬盘。

| 项目                           | 状态                 |
| ---------------------------- | ------------------ |
| 支持安全功能（Security Supported）   | 是（Yes）             |
| 安全功能启用（Security Enabled）     | 否（No）              |
| 安全锁定（Security Locked）        | 否（No）              |
| 安全冻结（Security Frozen）        | 否（No）              |
| 用户密码状态（HDD User Pwd Status）  | 未安装（NOT INSTALLED） |
| 主密码状态（HDD Master Pwd Status） | 已安装（INSTALLED）     |

设置硬盘密码后，建议重启系统以确保设置生效。

在 BIOS 中选择“放弃更改”或“保存更改”不会影响已经设置或清除的硬盘密码。

如果“设置用户密码”（Set User Password）选项被隐藏，请重启系统以重新启用该选项。

若要清除硬盘密码，只需将硬盘主密码的新密码设置为空（在输入密码的地方直接回车）。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://book.bsdcn.org/bios/security-an-quan/hdd-security.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
