Additional Disk got deleted

@Jessi Software Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I'm sorry to hear that you're experiencing issues with your Azure VM disk. If you have reattached the disk and it appears to be empty, it's possible that the data on the disk has been lost or corrupted. However, there are a few steps you can take to try to recover the data:

1. Check the disk status: Go to the Azure portal and check the status of the disk. If the disk status is "Unattached", it means that the disk is not currently attached to any VM. If the disk status is "Attached", it means that the disk is attached to a VM, but the data may have been lost or corrupted.
2. Check the VM logs: Check the logs for the VM to see if there are any errors or warnings related to the disk. You can access the logs from the Azure portal or by using Azure PowerShell or Azure CLI.
3. Use Azure Backup: If you have enabled Azure Backup for your VM, you may be able to recover the data from a backup. You can use the Azure portal or Azure PowerShell to restore the backup to a new disk.
4. If the issue still persists, resolution I would recommend you contact Azure support, so If you have a support plan, I request you file a support ticket, else please do let us know, we will try and  help you get a one-time free technical support. 

Additional information: If you have a backup of the VM you could restore it and its disk(s), or if you have a snapshot of the disk you could use that to create a copy of the disk.

If you have an existing backup and/or disk snapshot and you are unsure how to restore the VM/disk, please add a comment below and I will assist.

Please let us know if you have any further queries. I’m happy to assist you further.

Hi @Jessi Software ,

do you have a backup of the VM? Maybe created with Azure Backup?

If so you can restore the disk or files from the disk using existing backups.
