Question about data security in virtual machines

Dear azure community members:

Assuming that I have stored data in a virtual disk in azure virtual machine, when I free this disk, if it is assigned to another user, is it possible to recover the deleted data as in a normal PC.

Thanks for your reply!

    No, as it got a atleast two layers on top of the hardware. It's a volume linked to your VM from a hypervisor partition that is stored into the disk. Your VM got access only to the first level.

    When the volume is erased the volume is erased on the hypervisor, the hardware stay the same, but the partition table and all related information are erased, and when another volume is created from that space, the next VM just see the new volume presented to him, so it's all new.

    The way you state is when you have a direct access to the machine hardware, which is not the case here.
