我正在尝试使用 dd 将外部硬盘驱动器 ( 1.5T ) 克隆到第二个硬盘驱动器 ( 3T )。我正在 Unix 上工作，想要创建一个磁盘映像。
这是我正在使用的命令：
dd if=/dev/disk1 of=/Volumes/FreeAgent\ GoFlex\ Drive\ DENISE/SeaGate_AC.dmg conv=noerror
我使用以下命令来检查传输进度：
kill -INFO 1880
一开始它工作正常，下面是输出的示例：
8576952+0 records in
8576952+0 records out
4391399424 bytes transferred in 658.085533 secs (6672992 bytes/sec)
但过了一段时间，当我尝试访问目标 HD 时，终端没有响应，甚至我的 Finder 也崩溃了。
我尝试过使用同步选项，但结果相同
欢迎任何建议...
谢谢西蒙
以下是 slm 建议的 dmesg 输出：

两个驱动器都格式化为NTFS.它们安装的系统是Mac OSX 10.6.8.希捷提供的软件GoFlex用于访问 3TB 硬盘。
1.5TB HDD 出现故障，并且在启动期间Disk Utility扫描驱动器时出现故障。
答案1
我认为你的问题是你想写一个主引导记录（MBR）格式化的驱动器，MBR最多只能支持2TB。
你必须格式化你的3TB驾驶时使用GUID 分区表 (GPT) 布局。我建议使用以下命令对 3TB 驱动器进行分区分手了然后使用克隆齐拉复制2TB驱动器的数据到3TB驾驶。
