disk not shown in drivepool suddenly

[DenSataniskeHest]

Today i saw that drivepool was missing a disk. I could still access the missing disk through its mount point, but drivepool wont see it. 

The disk is a simple volume, i cant recall if its always been like that. But i suspect it has always been like that. How do i get this disk into drive pool again without lossing my data? I have no where to copy it temp.

i properly have to convert the dynamic disk to basic somehow?

Yes, a volume needs to be Simple and its disk needs to be Basic to be usable by DrivePool.

Windows Disk Management unfortunately does NOT support converting an in-use disk from Dynamic back to Basic without erasing it first.

To perform the conversion without data loss you would need to use a third-party partition manager with that capability, and there is still a risk; I would strongly advise having a backup first.
