我的外部硬盘损坏了,不确定是哪一个,我正在尝试修复它,或者至少从中获取一些数据。(硬盘的系统损坏已经发生过一次,但只需登录到Linux并插入设备就可以轻松解决,我现在希望出现类似的情况,虽然硬盘很旧,这意味着可能是硬件故障,但尝试一下不会有坏处)几周前,硬盘插入Windows时总是显示“格式化磁盘......”,但至少它显示了一些东西 - 现在它没有出现在Windows上,我在Linux上也找不到它。
我试过运行fdisk -l

它没有出现在 上,fdisk
并且无法识别 之后的 usb dmesg
。我不太懂 Linux,也不太了解这些命令打印出的信息,因此我正在寻找建议,看看下一步该如何尝试让硬盘起死回生。(最初的计划只是在硬盘上运行“testdisk”,但它在 testdisk 设备列表中也无法识别。
