Hi,

If the disk status is Offline and the disk's name changes to Missing, the disk was recently available on the system but can no longer be located or identified. The missing disk may be corrupted, powered down, or disconnected.

Please check the following things:

1. Repair any disk, controller, or cable problems.
2. Make sure that the physical disk is turned on, plugged in, and attached to the computer.
3. Next, use the Reactivate Disk command to bring the disk back online.
4. Try the troubleshooting steps described in A disk's status is Not Initialized or the disk is missing entirely.
5. If the disk status remains Offline and the disk name remains Missing, and you determine that the disk has a problem that cannot be repaired, you can remove the disk from the system by selecting and holding (or right-clicking) the disk and then clicking Remove Disk). However, before you can remove the disk, you must delete all volumes (or mirrors) on the disk. You can save any mirrored volumes on the disk by removing the mirror instead of the entire volume. Deleting a volume destroys the data in the volume, so you should remove a disk only if you are absolutely certain that the disk is permanently damaged and unusable. https://learn.microsoft.com/en-us/windows-server/storage/disk-management/troubleshooting-disk-management#:\~:text=A%20dynamic%20disk's%20status%20is%20Offline%20or%20Missing,-Cause%3A%20An%20Offline&text=The%20missing%20disk%20may%20be,and%20attached%20to%20the%20computer.

Thanks for your time!
