由于分区问题而无法访问HDD

因此，我有一个充满媒体，照片音乐等内容的硬盘。它在Windows 10中运行良好，但是由于恢复为Windows 8（操作系统位于SSD上），因此无法在计算机中找到该驱动器。我已经检查了数百篇文章，这是我所拥有的：

diskpart显示磁盘。它显示了2个分区，两个分区均未附加任何卷。当我列出卷时，它显示了其他磁盘的卷：

磁盘管理将其显示为存储池，但是当我右键单击时，所有选项均显示为灰色：

分区向导甚至不显示驱动器：

FindAndMount甚至不会显示任何分区：

Can you please advise on how I can get this seemingly healthy partition to show up in My Computer. I know I have an option to try 'clean' in DiskPart but it's really important that I recover the files on the drive so that really is a last resort.

Edit: Just to add to this, I never intentionally created a storage pool so I'm not sure why windows decided that this HDD should be one.
