My developers uploaded a VHD to google drive for me to download and upload to my own azure account. I downloaded it to my SD card (an external storage device) Whenever I upload the VHD to a resource group under "disks" on Azure Storage Explorer I get the following error. I would be very grateful for some help in what I am doing wrong and how I can upload this VHD. P.s.: I would be grateful for solutions to this issue, not other ways the developers can give me access. These alternatives are limited due to some limitations on my account and other factors. Thank you.

Hello @yoav If you're encountering an error while uploading a .vhd file to Azure, there are a few things you can check to resolve the issue: Ensure that the .vhd file is in the correct format. Azure supports both .vhd and .vhdx formats, but the file must be in the fixed format, not dynamic. Check the size of the .vhd file. Azure has a maximum size limit of 2 TB for .vhd files. If your file is larger than this, you'll need to split it into multiple .vhd files. Ensure that the .vhd file is not corrupted. You can use the 'chkdsk' command in Windows to check the file system for errors. Ensure that you have the correct permissions to upload the .vhd file to Azure. You'll need to have the appropriate role-based access control (RBAC) permissions to upload the file. If you're using the Azure portal to upload the .vhd file, ensure that you have a stable internet connection and no interruption during the upload process can cause errors. If you've checked all of these items and are still encountering an error, you can try uploading the .vhd file using the Azure CLI or Azure PowerShell. These tools provide more detailed error messages that can help you troubleshoot the issue. You can also refer to the following Microsoft documentation for more information on preparing a Windows VHD to upload to Azure: https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/virtual-machines/windows/prepare-for-upload-vhd-image.md Reference: https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/virtual-machines/linux/oracle-create-upload-vhd.md https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/virtual-machines/windows/prepare-for-upload-vhd-image.md Hope this helps. Let me know if you need further assistance.

Thank you very much @Abdul Sajid Mohammed When I downloaded the file, Azure Storage Expolrere did not recognise it as .vhd. I don't think it was saved as such. So, I manually added ".vhd" to the file name. Then it worked fine. Do you think this may be the root cause of the issue and relate to point #1 that you outlined? I am very grateful for your help. Many thanks, Yoav

Hi @Abdul Sajid Mohammed

Thank you very much for the reply.

When I initially downloaded the file, Azure Storage Explorer did not recognise it as .vhd. So, I added .vhd to the filename myself, manually. Then it recognised it.

Do you think this could be related to what you outlined in point #1, and could be the root cause of the error?

I am most grateful for your help.

Many thanks,

Yoav

Hi @Abdul Sajid Mohammed , the issue has not been resolved.

I redownloaded the file and it is not recognised as .vhd. What do you recommend I do?

Hello @yoav

Sorry to hear that.

For your second attempt, can u please share your steps you are following to download this file and where you are saving it?

Such as from where and how you are downloading this VHD? Are u downloading directly from somewhere and then uploading to Azure Storage? Or just using the same previous copy from your Google drive? and how are you trying to upload such as Azure Portal or CLI? And please share screenshots of the Exact Errors.

Look forward to your response.

I am downloading the file from Google Drive to my PC

I am saving it to my PC. It saves with an All Files extension.

I am currently redownloading it, as I messed something up in my last download. I will attempt to upload via ASE tomorrow and keep you posted.

Thank you for your continued help.

@Abdul Sajid Mohammed @Abdul Sajid Mohammed

I have tried again and it failed. Here are the steps I followed.

Download VHD file from Google Drive to Desktop folder

Open Azure Storage Explorer

Upload VHD file with default settings apart from OS which I change to Linux

Upload fails after 50 minutes, displaying the below message:

Please advise what I can do. I am going to check now if I can privately share with you the log details.

It says: "

"message": "The specified cookie value in VHD footer indicates that disk 'abcd' with blob xxxx not a supported VHD. Disk is expected to have cookie value 'conectix'."

Does this mean the file is corrupted?

I look forward to hearing from you. Yoav

Hello @yoav

Unfortunately, I cannot comment on how Google Drive handles these VHD files and what formats or extensions it overwrites.

This error message shared by you is possibly due to the issue that you are attempting to use a Virtual Hard Disk (VHD) with an unsupported format. Each VHD file contains a footer, which contains information about the disk, including a cookie value that identifies the disk as a valid VHD.

The error message specifically indicates that the cookie value in the VHD footer is not the expected value of 'conectix'. This means that the VHD file may be corrupted or in an unsupported format.

To resolve this issue, you may need to check the VHD file for corruption or attempt to recreate the VHD file with the correct cookie value. And possibly try to grant a guest access to your Azure Storage account to the person who is trying to share you a VHD, so that way they can access and upload the VHD file directly into your azure storage, that will eliminate your need of Google Drive here.

Hope this helps. Please let me know if any questions.
