If you are backing up your files and data using Windows Backup, to multiple CD or DVD discs and you receive the following message: Error: Unspecified error (0×80004005) , then reason could be that you closed the progress dialog box before the backup completed!
To avoid getting this kind of errors, simply do not close the progress dialog box before the backup is complete!
This issue is specifically observed in the following scenarios:
- Windows Backup is configured to back up to CD\DVD
- The backup starts and displays a notification in Action Center asking for first disc. You click More information
- Windows displays the Backup progress dialog box and the Change Media dialog displays on top of the Backup progress dialog box
- You insert a CD\DVD disc to continue with backup and you close the Backup progress dialog box
- The backup finishes writing to first disc and shows another notification in Action Center asking for a second CD\DVD disc
- Clicking More information is followed by an unspecified error and the backup fails.
