Azure Data Box Export stalled at 99.99%

I shipped a SATA HDD to the Central US datacenter to export my blobs via the import/export service.

The drive has been received and the copy job ran and got to 99.99% complete.

It has been sitting at that status for several days now. What can be done to complete the job and have this drive shipped back to me?.

    Hello Andy Engle

    If your Azure Import/Export job is stuck at 99.99% completion for several days after shipping a SATA HDD to the Central US datacenter, here are steps to resolve the issue and complete the job for drive return.

    1.Review Job Status in Azure Portal to check your Import/Export job under the associated storage account. Check the job’s “Overview” pane for detailed status messages or error logs. The copy log, stored in the databoxcopylog container in your storage account, lists failed copy operations and error details (e.g., corrupted blobs or inaccessible files)

    Refer: https://v4.hkg1.meaqua.org/en-us/azure/import-export/storage-import-export-tool-reviewing-job-status-v1

    If the status remains “Transferring” or “Copying,” look for errors related to specific blobs or drive issues, such as unsupported formats or file system errors.

    Refer: https://v4.hkg1.meaqua.org/en-us/azure/databox/data-box-troubleshoot

    2.Verify Drive Requirements like SATA HDD meets Azure’s specifications: 3.5-inch SATA II/III drive with 512-byte sectors (4K sectors are not supported) and formatted as NTFS. https://v4.hkg1.meaqua.org/en-us/azure/import-export/storage-import-export-requirements

    3.Sometimes the job may be stuck due to corrupted or inaccessible blobs. The copy log will detail failed transfers, such as invalid directory names or file system errors.
