Disk Management - problem with dynamic volume

Question

Hi Everyone,

Windows does not recognize me a dynamic volume configured partly in mirroring and partly in spanning, consisting of two 3TB disks.

In short, having run out of space, I added two new 18TB drives by enabling RAID1 from controller on X570 motherboard and installing AMD drivers.

Before the procedure I disconnected the old 3TB disks (those in mirroring + spanning) and I reconnected them after the configuration of the new disks, to copy their contents.

Surprisingly, a 3TB physical disk is no longer recognized and disk management reports it to me.

I tried to unplug the new 18TB disks, reset the AHCI option from bios, but the situation doesn't change.

More precisely, disk management finds me an "Foreign" disk, which I could import. Before importing it rightly recognizes that it is a disk with a mirrored volume and a spanned volume. At the time of import, however, it informs me that the procedure can cause data loss.

So here I stopped.

I have not yet trusted to reactivate the recognized disk, fearing that it may lose data on the spanned portion, and perhaps not only.

So I wanted to ask if there is a way to automatically recognize the drives to Windows as before.

Or if there is a safe procedure to reactivate the unrecognized disk automatically.

Finally, a curiosity: in the spanned portion, the data are stored in a raw on both disks (therefore without the possibility of recovery) or are they sorted progressively while remaining readable?

Given the delicacy of the question, I thank anyone who can give me safe indications!

Answer 1

I reply myself:
reading on other forums I found who tried to import the external disk, despite the warning message. I tried too.
The spanned volume started working again immediately. The mirrored volume was imported as two separate volumes with two different letters, obviously one a copy of the other. I'm feel lucky

Hello there,

When you run into dynamic volume’s status is Failed on Windows , you can take the following causes into consideration.

-The dynamic disk is offline.
-The file system is corrupt.
-The dynamic disk is damaged.

If you have a disk that doesn't appear in File Explorer and is listed in Disk Management as Not Initialized, it could be because the disk doesn't have a valid disk signature. Basically this means that the disk has never been initialized and formatted, or the drive formatting has become corrupted somehow.

You can safely follow the troubleshooting steps from here and see if that helps https://learn.microsoft.com/en-us/windows-server/storage/disk-management/troubleshooting-disk-management
