Answer 1

Here is an article from microsoft on how to find and delete them:
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/find-unattached-disks

And if you are using
Get-AzDisk | Where-Object {$_.ManagedBy -eq $null}

you should get a list of all unassigned disks in azure. Or use the script provided in the first part of the help article and keep the delete variable on 0, it will then output the id's of the disks no assigned too.

Hi @Praveen Mittapalli ,

To get an attached but unallocated disk your going to look for disks where the PartitionStyle is 'RAW'. To do this on the at Windows OS level you should run Get-Disk | Where-Object PartitionStyle –Eq 'RAW' in Powershell which will get you all of your unallocated disks attached at the Windows OS Level but are not allocated.
