Fix 0x8078002A Error in Windows 7 Backup to 3TB Seagate External Drive

backupexternal hard drivewindows 7

I'm using the Windows 7 backup and restore utility to create a system image and personal file backup to an external Seagate GoFlex 3TB disk. I got the following error:

One of the backup files could not be created.
Details: The request could not be performed because of an I/O device error.
Error code: 0x8078002A

I searched all over the internet and found these two related discussions (discussion 1 and discussion 2). Note the 1st discussion is for a Western Digital drive, which seem to have a solution with the WD Quick Formatter tool. But I downloaded that software and it cannot detect my Seagate drive. The 2nd discussion is directly relevant but it does not offer a solution. I've spent days on this and am at a loss…

Please help if you know what to do to make it work! Thank you!

Here is the official answer from Seagate support. Hopefully this sheds some light. One word of caution. There are various online complaints about DiscWizard and my experience with it hasn't been very good either (eg. backup has to be on an entire drive/partition, instead of some folder; the included DriveCleanser doesn't actually do anything).

Thank you for contacting Seagate Support. I am sorry for any inconvenience but Windows Backup does not support 4K sectors. All hard drives now use 4K sectors. You will need to use an older model external hard drive or a different image backup program. Seagate has a program from Acronis called DiscWizard that works on 4K sector hard drives.

Here is a link for the software:
