在尝试从出现故障的硬盘驱动器中恢复数据的过程中,我正在运行命令ddrescue
。
该命令已经运行了9天,从磁盘活动的声音中我认为它可能正在做某事。一直以来,命令行输出看起来或多或少是静态的:
$ sudo ddrescue -r3 /dev/sdb /home/dave/RECOVERY/usb500.image /home/dave/recovery_usb500.logfile
Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 0 B, errsize: 0 B, errors: 0
Current status
rescued: 0 B, errsize: 500 GB, current rate: 0 B/s
ipos: 2539 MB, errors: 1, average rate: 0 B/s
opos: 2539 MB, time from last successful read: 9.7 d
Splitting failed blocks...
一直在变化的一部分是它所说的ipos
和opos
。起床大约需要9天500000 MB
,这是发生故障的磁盘驱动器的大小。但是,到达目的地后,它回落至最低点0
并再次开始上升。在我写这篇文章的时候,它是在不断增加2580 MB
。
正在创建的图像文件的长度为0个字节。
日志文件大小约为3MB,如下所示:
# Rescue Logfile. Created by GNU ddrescue version 1.14
# Command line: ddrescue -r3 /dev/sdb /home/dave/RECOVERY/usb500.image /home/dave/recovery_usb500.logfile
# current_pos current_status

0x00862000 0x00014800 /
0x00876800 0x00800400 -
~~~~~~edited for brevity ~~~~~~~~
0x74702CCE00 0x00320000 -
0x74705ECE00 0x00025800 /
0x7470612600 0x005F3A00 -
我开始担心这只是浪费时间,根本没有恢复任何数据。
此输出是否表明正在发生有用的事情?
是否有任何理由让ddrescue
命令按原样继续执行,还是应该停止它并执行其他操作?
这是最新的内容 /var/log/syslog
