Error description: The blob or file is incorrectly aligned.

Suggested resolution: The page blob share on Data Box or Data Box Heavy only supports files that are 512 bytes aligned (for example, VHD/VHDX). Any data copied to the page blob share is uploaded to Azure as page blobs.

Remove any non-VHD/VHDX data from the page blob share. You can use shares for block blob or Azure files for generic data.

For more information, see Overview of Page blobs.

ERROR_BLOB_OR_FILE_TYPE_UNSUPPORTED

Error description: An unsupported file type is present in a managed disk share. Only fixed VHDs are allowed.
