我有一个有坏块的 SSD。它阻止 Windows 加载，但第二个操作系统 - Linux 运行良好。最初它甚至在有坏块的情况下也能工作。我已经制作了磁盘的低级副本，目前正在使用新磁盘，但我也尝试恢复旧磁盘。因此，我运行 AOEMI Parion Assistant 并进行表面扫描，希望它能替换坏块，至少我可以加载 Windows。但没有运气 - 表面扫描发现的坏块比以前更多。现在我无法访问我的旧磁盘。AOEMI 分区助手无法再访问它。Fdisk 不将其视为设备。dmesg 有这样的输出：

关于如何访问我的磁盘（至少要格式化它）有什么建议吗？为什么发现坏块会阻止它被访问？
答案1
我会运行一个分区实时 USB，看看是否可以从那里进行格式化。
您可以尝试不同的 SATA / M2 插槽、不同的电缆，如果可能的话，还可以尝试不同的机器，但我从自己的 SSD 中知道，当它们出现故障时，它们会很快出现故障并且根本无法被检测到。
