中有一条消息Disks：磁盘可能很快就会出现故障
我不知道该硬盘发生了什么事。
我尝试使用损坏的分区制作映像Disks，但在复制 15GB 的分区后，我已经遇到了 2GB 的读取错误！复制时间增加到 2 周。
当我尝试复制dd时：
sudo dd if=/dev/sdb2 conv=sync,noerror bs=64K status=progress | gzip -c > /media/zentala/Biblioteka/lenovo2tb.image.gz
5177344 bytes (5,2 MB, 4,9 MiB) copied, 3 s, 1,5 MB/s

............................
问题是：有没有关于如何从该驱动器检索数据的选项......？那它发生了什么事？

如果驱动器损坏，您在这种情况下无能为力。您可以尝试使用 恢复设备上的剩余内容ddrescue。这将花费很长时间，您可能需要中断并重新启动此过程几次。
