我怀疑公司里有人决定进行分区跨越，即：
（取自 Linux Debian 9）
驱动器 #1：
Disk /dev/sdc: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x11722464
Device Boot Start End Sectors Size Id Type
/dev/sdc1 * 2048 206847 204800 100M 7 HPFS/NTFS/exFAT
/dev/sdc2 206848 1952612351 1952405504 931G 7 HPFS/NTFS/exFAT
/dev/sdc3 1952612352 1953533951 921600 450M 27 Hidden NTFS WinRE
驱动器 #2：
Disk /dev/sdd: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
您可以看到，两个硬盘的大小都是 500 GB。
同时，查看分区的大小/dev/sdc2，它是驱动器大小的两倍。
我试过：
# ldmtool create all
[
]
这里没有结果。
我对 Windows 10 相当熟悉，但对跨磁盘或分区并不熟悉。
原来的电脑坏了。无法修复，我很确定如果真的有跨分区，设置它的人已经不再在这里工作，并且拒绝在这件事上帮助我们。
两个驱动器都快速旋转并且没有问题，所以我真的认为这应该是软件问题。
据我所知，它上面安装了 Windows 10，是从 Windows 7 升级而来的。
我们购买了一台装有 Windows 10 的新电脑并插入了这些驱动器，希望它能够自动检测跨区分区，但 Windows 驱动器管理器提示我启动第二个（从 Linux 看为未格式化的）驱动器。
如果有对跨卷有经验的用户提供任何线索和提示，我们将不胜感激。

安装dmraid并重新启动 Linux 服务器后，除了上述内容之外，我还看到：

我对跨区分区或驱动器的怀疑是错误的。
它实际上是假 RAID0在 的帮助下发现dmraid。
