Windows 7 backup failure

I get error messages (see below) when attempting backup to external HD. How to cure? I'm guessing the I/O device cited is not the external drive since I am able to read files from this drive. 

TIA for any assistance.

    We're glad you got your data file saved.

    For your reference regarding those error messages:

    • Error message 0x8078002A occurs due an error in Bytes/Sector when using Microsoft Backup Utility.

    Win7 backup error 0x8078002a

    • Error message 0x80070003 happens when some files in the Windows Update are missing.

    Windows Update error "0x80070002" or "0x80070003"

    Regards.

    Error message 0x8078002A occurs due an error in Bytes/Sector when using Microsoft Backup Utility.

    Win7 backup error 0x8078002a

    I did see instructions for investigating the 8002 error but did not proceed. The same drive did not produce any errors pre-OS reinstall so I figured the drive isn't the problem - probably some obscure thing in the OS.

    Thanks for the help.

    Hi,

    The error code 0x8078002A may arise due to a compatibility issue. It is present on hard drives with advanced format also known as 4k sectors when being used on a Windows 7 utility backup system. The said 4K sectors may experience an error when backing up a full system image, but doesn't mean that the backup is not usable. In addition, the backup works fine for personal data and there are software that is offered by the manufacturer to support full imaging system.

    Let us know should you need further assistance.
