The early normal cloud disk does not support uninstall operations. Please change the normal cloud disk into a separate cloud disk in the late renewal, and then unload and mount the operation.

When unloading a data disk, note the following:

Under Windows operating systems, to ensure data integrity, it is recommended that you suspend read and write operations on all file systems for that disk, or that data that is not finished reading or writing will be lost.
