Introduction
An Azure VM Data Disk is a managed disk that provides additional storage for a Virtual Machine (VM) in Microsoft Azure. It is separate from the OS disk and is used to store application data, databases and other files.
In this article, we will be looking at step-by-step guidelines on how to add data disk and initialize it to make it usable on Azure VM.
