我正在尝试恢复突然发生故障的 1TB 硬盘。我分两次运行了 ddrescue。第一个命令是
ubuntu@ubuntu:~$ sudo ddrescue -f /dev/sdb /dev/sda /media/ubuntu/17BE6E9E17BE6E9E/ddr.log
GNU ddrescue 1.19
Press Ctrl-C to interrupt
rescued: 0 B, errsize: 756 MB, current rate: 0 B/s
ipos: 702021 kB, errors: 837, average rate: 0 B/s
opos: 702021 kB, run time: 28.16 m, successful read: 28.16 m ago
Copying non-tried blocks... Pass 3 (forwards)^C
Interrupted by user
因为“获救：0 B”，我决定停下来多读一些书。此时日志文件的输出是
# Rescue Logfile. Created by GNU ddrescue version 1.19

我读了更多内容并决定运行更长时间（源驱动器不同，但这不是不正确/偶然的）：
ubuntu@ubuntu:~$ sudo ddrescue -f -d /dev/sdc /dev/sda /media/ubuntu/17BE6E9E17BE6E9E/ddr.log
GNU ddrescue 1.19
Press Ctrl-C to interrupt

此命令后的日志是

我注意到该驱动器似乎比 1TB 小得多
/0/2/0.0.0 /dev/sdc disk 4142MB ST1000DM003
虽然在运行时听起来并没有发出不寻常的噪音（但在通电时是的）。该驱动器是否已确认已死亡？我觉得奇怪的是驱动器和型号仍然可以被识别。
