Identify, detach and delete a non used unallocated unmanaged disk

Question

I have an unallocated disk on a VM with 16 unmanaged disks attached, and I want to identify that exact drive on the list of drives so I can detach it and delete it.

I have several 512 GB disks, how can I know which one is the one unallocated?

List unmanaged disks of a VM: az vm unmanaged-disk list provides complete details of the disk.

Find and delete unattached Azure managed and unmanaged disks using Azure Portal or Powershell

You can also monitor the free disk space per drive with Azure Monitor do the following:

• Enable Guest Operating System OS Metrics for the VM.
• In the Azure Portal select the Virtual Machine.
• Click Diagnostics Settings (under Monitoring).
• Click the Performance counters tab.
• Click the Custom button.
• In the textbox add the custom metric for the drive you would like. e.g. \LogicalDisk(C:)\% Free Space.
• Click Add and set the Unit to Percent.

For more information, please refer to this article: https://learn.microsoft.com/en-us/azure/azure-monitor/platform/diagnostic-settings

If you still find any difficulties, I would like to work closer on this issue.
