根据文档，Clonezilla 支持使用选项 -icds 克隆到较小的驱动器。我们来引用一下：
如果你确定映像中的所有数据都可以放入较小的磁盘，即不会被写入错误的磁盘空间，则可以选中选项“-icds”
这就是我的情况。我正尝试将操作系统和数据从我朋友的故障驱动器转移到新驱动器。我真的想避免重新安装 Win Vista 32 位和所有软件。
源盘：SATA 320 GB WD 硬盘，有两个分区（C: 和 D:），有几个坏扇区。整个 320 GB 中大约使用了 50 GB。
目标磁盘：Crucial MX500 250 GB。
我在 Parted Magic 中运行当前的 UBCD 5.3.8 和 Clonezilla。除了默认设置外，我还添加了以下选项：
- -救援：忽略坏扇区
- —icds：这是允许克隆到较小驱动器的重要步骤
- -k1：按比例创建分区表
但是，克隆因错误而停止：
目标分区大小（163830 MB）小于源分区（209716 MB）。使用选项 -C 禁用大小检查（危险）。无法将 /dev/sda1 克隆到 /dev/sdb1
为什么 Clonezilla 不遵守 -icds 设置，不使用 -C 开关运行 Partclone？如何让它执行克隆？
我附上了日志文件的内容：

答案1
正式来说，Clonezilla 要求目标驱动器的大小等于或大于主驱动器。
但是，这是可以做到的。您遇到的问题不是磁盘的大小，而是分割（s）。如果分区大小总和大于目标驱动器，Clonezilla 将失败。您需要缩小主驱动器上的分区前运行 Clonezilla 与-icds。
这可以在 GParted Live 环境中或操作系统内完成（取决于设置）。
在 Clonezilla 中，选择专家模式并启用“-icds”选项。您还需要选择“按比例调整分区表大小”选项。
或者，还有其他磁盘克隆软件程序可以自动执行此操作。
