Windows 7: Backup failed error 0x8078002A on an external 3Tb drive

It is an old thread but I would personally be careful about using proprietary HDD manufacturers backup software. Some do license 3rd party applications (eg. ACRONIS variants) which may be ok.

If you have a drive > 2TB then you should be formatting it GPT and the latest version of free or paid Macrium Reflect should support this.
