In the Windows operating system, each disk is identified by a unique DiskID. When multiple volumes are created from the same snapshot, these volumes inherit the same DiskID. If multiple volumes with the same DiskID are mounted to the same instance at the same time, and you perform operations on them, such as modifying disk status or formatting, the Windows operating system may fail to correctly identify target disks.

Solutions

Click the Windows icon.

Expand "Windows PowerShell", right-click "Windows PowerShell", and then select "More > Run as administrator".

In PowerShell, execute the following command to open DiskPart.

diskpart

Execute the following command to select the faulty disk.

sel disk 2

tip

In the example provided in this topic, Disk 2 is the faulty disk. Replace 2 with the actual serial number of the faulty disk.

If you cannot select the faulty disk, restart the instance and then try again.

Execute the following command to clear the read-only attribute of the faulty disk.

attr disk clear readonly

Click the Windows icon.

Select "Windows System > Run".

Enter diskmgmt.msc and click the "OK" button.

In "Disk Management", right-click the target disk, and then click the "Online" button.

Then, the disk identification exception is successfully fixed.
