我首先在 StackExchange Unix&Linux 社区板上发帖，因为它似乎是我正在寻找的答案类型最有可能的地方。我希望有人能指出我正确的方向。
过去两天我一直在尝试从 Iomega HMNHD CE 访问旧驱动器（请参见此处：http://iomega.nas-central.org/wiki/Category:Home_Media_CE），据我所知，驱动器使用 MD 创建其“raid”配置（根据恢复指南中提供的引导日志）。此外，我尝试遵循原始黑客指南中的说明（http://iomega.nas-central.org/wiki/Root_access_enabling_(Home_Media_CE)），但是以前在我的老式 PC 上运行的功能不再以同样的方式运行。我现在正在使用现代 Ubuntu 来尝试执行此操作。我最初可能会使用 Debian lenny 之类的东西。
物理硬盘处于完美工作状态。更重要的是，我非常生疏，我所拥有的任何 UNIX/Linux 功能似乎都抛弃了我。
注意：我并不是尝试“恢复”驱动器，而是尝试使用已通过 USB 连接驱动器的 PC 访问驱动器上的数据分区。驱动器正在工作并正确连接，问题在于需要安装设备/分区/卷的任何方式。
问题是，虽然我可以看到驱动器，但分区无法安装。我在这个阶段不感兴趣，特别是对第一个分区（sdc1），因为它包含两个卷，一个是用于启动设备的 initramfs 映像，以及一系列嵌套应用程序和系统相关的卷 - 如果最坏的情况发生，我如果想要这些数据，可以从原始“固件”映像中重新创建它。然而，第二个分区 (sdc2) 包含数据卷，所有 SMB 共享都位于其中。我正在尝试检索的正是这些数据。
此内容已经过修改和整理，以反映已收到的建议

上述所有命令和输出都已尝试过，但到目前为止我还无法理解我缺少什么才能使其正常工作。
注意：NAS 中的驱动器“正常工作”，但 NAS 中仅使用第一个分区 (SDC1)，第二个分区 (SDC2) 不可用 - 无共享等。
