损坏的 U 盘不断消失，无法进行任何修复操作

2024-6-8 • tag-icon

我正在尝试修复损坏的 USB 闪存盘。这是一个新的 USB 闪存盘，在同事尝试对其进行加密后，它就无法正常工作了。不幸的是，我不知道加密是如何被破坏的，但我认为重要数据（分区表或类似的东西）在这个过程中被破坏了。

当我插入它时，系统会找到它并显示在lsusb和的输出中lsblk。

然而，当我随后尝试运行ddorbadblocks或mkfs执行某些操作时，所有这些命令最终都会由于 I/O 错误而失败。发生这种情况时，随身碟也不会出现在lsusb或的输出中lsblk。因此，我假设在此过程中操作系统以某种方式断开了随身碟的连接。

我可以做什么来保持连接？

dmesg有这样说：
