我用 2 TB 硬盘替换了 1 TB 硬盘（它包含一个 EXT4 分区，该分区内有许多指向备份文件/目录的硬链接。它还有一堆常规文件/目录），现在我正尝试从外部硬盘读取器将前者的数据复制回新磁盘。不幸的是，旧磁盘似乎不喜欢被拖回家，现在它拒绝安装其唯一的分区。
gdisk /dev/sdf1显示：

让我感到困惑的是奇怪的二级分区表和报告末尾声称的不真实的 7.3 TiB。磁盘在取出之前运行正常，即使现在通过外部方式连接，智能工具健康状况没有问题。
更多信息：
swapspace我猜问题与磁盘运行时在该分区上启用服务有关。testdisk实用程序检测到几个交换分区，我猜是swapspace创建用于保存交换数据的交换文件。也许这些假“分区”让 gdisk 误以为有 7 TB 的磁盘空间……
有什么想法/指导吗？

最后，这确实都是由于硬盘读取器不兼容造成的！当我将硬盘重新连接到内部 SATA 端口时，它立即被识别。
需要说明的是，HDD 读取器是一款全合一硬盘坞站 (型号 875)以及相应的lsusb命令输出：
