+#+TITLE: 记一次帮老师修U盘
+#+DESCRIPTION: 驱动器 F 中的磁盘未格式化, 想现在格式化吗?
+#+DATE: <2022-11-13 日>
+#+OPTIONS: toc:nil num:nil
+
+* 发生甚么事了
+老师上课放(U盘里)视频的时候 "啪" 把U盘拔了!
+下一次插上就提示 "是否格式化" :)
+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: [[https://www.ventoy.net][Ventoy]] 启动盘
+
+* 咋整
+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)
+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
+
+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
+
+** 第一次尝试
+把老师的U盘插上, "嘎嗒"一声熟悉的 gnome 提示音, U盘没显示
+有 =/dev/sdc=
+=mount -t= 试试? 是不是没文件系统坏了没识别? 不是
+=fsck= 试试? 不行
+嗯??? 似乎有点超出我的知识储备和经验了
+** 第二次尝试
+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
+然后查了一下(当然用英文查), 有没有能修复分区表的? [[https://www.cgsecurity.org][testdisk]]
+然后先用 =dd= 整盘备份一下, 跑 testdisk
+很简单就把分区表恢复出来了!
+
+那就开始拷文件吧..."文件不完整"
+** 第三次尝试
+和 testdisk 一家的软件还有 =photorec=, 我似乎在 [[https://linux.cn][linuxcn]] 见过(懒得去找链接了)
+这东西一看就知道是通过文件头来识别并恢复文件的
+那就跑呗
+一节课之后, 文件(和曾经被删除的)都回来了
+开心!
+
+* 接活?
+:PROPERTIES:
+:CUSTOM_ID: ad
+:END:
+我可以比较廉价的进行数据恢复
+联系我后将磁盘镜像传到 FTP 服务器, *不接百度网盘*
+暂定价如下:
+** 16GiB 以下 0.3 XMR
+** 16~64GiB 0.5 XMR

+#+BEGIN_COMMENT
+一同学有坏的 32G盘(很早之前坏的), 给我恢复
+
+看到是 =/dev/sda1= 知道分区表没坏
+不稳定, 总是掉盘(原因可能是过热), 这估计也是坏的原因了, 所以我就 =watch -n 20 ls /dev/sd*= 检查着
+先用 dd 备份一份...结果他给我的备份盘是 FAT32, 镜像太大了, 所以就暂时再用 gparted 分一个 NTFS 的分区
+...但是总是到 12G 的时候掉盘
+那就直接 =fsck.fat -a=? 还是掉盘
+我尝试把其中的一个大文件先移动走再 fsck, 但是 "Read-only file system"
+
+emm...硬件问题还是没办法
