<h2>发生甚么事了</h2>
|
|
<div class="outline-text-2">
|
|
<p>
|
|
老师上课放(U盘里)视频的时候 "啪" 把U盘拔了!<br />
|
|
下一次插上就提示 "是否格式化" :)<br />
|
|
反正闲时间太多, 我就准备试试给修复一下, 使用我在我文具盒里待了两年的工具箱: <a href="https://www.ventoy.net">Ventoy</a> 启动盘<br />
|
|
</p>

<h2>咋整</h2>
|
|
<div class="outline-text-2">
|
|
<p>
|
|
我首先是对 Linux 文件系统有一定基础, 也进行过不少操作(如多次安装gentoo和arch)<br />
|
|
也搞过一些文件系统损坏的事(比如调分区坏过C盘), 还算有经验<br />
|
|
</p>
|
|
|
|
<p>
|
|
于是我上老师电脑启动了两年前放在工具箱盘里的 Fedora Workstation 34<br />
|
|
</p>
|
|
</div>
|
|
|
|
<div class="outline-3">
|
|
<h3>第一次尝试</h3>
|
|
<div class="outline-text-3">
|
|
<p>
|
|
把老师的U盘插上, "嘎嗒"一声熟悉的 gnome 提示音, U盘没显示<br />
|
|
有 <code>/dev/sdc</code><br />
|
|
<code>mount -t</code> 试试? 是不是没文件系统坏了没识别? 不是<br />
|
|
<code>fsck</code> 试试? 不行<br />
|
|
嗯??? 似乎有点超出我的知识储备和经验了<br />
|
|
</p>
|
|
</div>
|
|
</div>
|
|
<div class="outline-3">
|
|
<h3>第二次尝试</h3>
|
|
<div class="outline-text-3">
|
|
<p>
|
|
只有一个整盘, 没有分区号? 凭直觉, 我觉得那就是分区表坏了<br />
|
|
然后查了一下(当然用英文查), 有没有能修复分区表的? <a href="https://www.cgsecurity.org">testdisk</a><br />
|
|
然后先用 <code>dd</code> 整盘备份一下, 跑 testdisk<br />
|
|
很简单就把分区表恢复出来了!<br />
|
|
</p>
|
|
|
|
<p>
|
|
那就开始拷文件吧…"文件不完整"<br />
|
|
</p>
|
|
</div>
|
|
</div>
|
|
<div class="outline-3">
|
|
<h3>第三次尝试</h3>
|
|
<div class="outline-text-3">
|
|
<p>
|
|
和 testdisk 一家的软件还有 <code>photorec</code>, 我似乎在 <a href="https://linux.cn">linuxcn</a> 见过(懒得去找链接了)<br />
|
|
这东西一看就知道是通过文件头来识别并恢复文件的<br />
|
|
那就跑呗<br />
|
|
一节课之后, 文件(和曾经被删除的)都回来了<br />
|
|
开心!<br />

我可以比较廉价的进行数据恢复<br />
|
|
联系我后将磁盘镜像传到 FTP 服务器, <b>不接百度网盘</b><br />

暂定价如下:<br />

恢复完之后我想瞅瞅那些教学视频, 正常来讲 f34 应该有解码器的, 但是没有<br />
|
|
是不是我连着网给我删了?<br />
