问题
All of the instructions available online for deleting a disk from a non-existent VM relate to the older Azure UI which does not contain the same menu commands as the new Portal. Therefore I need instructions for deleting an orphaned disk using the new Azure Management Portal. Instructions for the old portal are worthless for this action.
回答1:
Azure VM disks are stored in Azure Storage (blob containers).
Open http://portal.azure.com, click All Resources and locate the storage account, which you can manage there (for the entire account).
Or, to remove just that blob, get the Storage Explorer from here: http://storageexplorer.com/ - enter your credentials and use it to remove the required blob.
