Hi,
I bought a 2nd gen Dell 14R laptop a month ago. I haven't used it yet, because I want to back it up before anything bad happens to it. So I am trying to back it up onto an iOmega 500GB external hard drive, using Windows backup.
However, when the information is backing up, it only gets to about 60%, before it stops and says that an error has caused the back up to fail.
The error code is 0x8078002A. I also tried to backup my sister’s new 2nd gen Dell 15R laptop using the same device and I received the same error code.
I do not know what else to do to make the back up successfully. I have been working on it for a month.

Unable to use Windows 7 backup
 I think it has something to do with me swapping out my HD with a new one. This is on Windows Server 2008 x64.

Unable to use Windows 7 backup
Mr. John,
It is a very common problem reported On Microsoft site especially for windows vista and windows 7. This error appears for some particular external hard disks but not for everyone.
Try taking windows back up using some other disk if it works then fine. But if you have to use same drive again and again, try this non technical but urgent solution reported by some of the users having same issue.
Plug in the drive before logging into windows and start taking back up before starting any other activity. According to the users it helped.
Have a good day.
Unable to use Windows 7 backup
Error 0x8078002A usually incurs when using the backup utility in Windows 7 and trying to back up 2.5 or 3TB drive. The error will trigger if you are using a drive that has 4K Logical sector sizes that can be found on a large external drive.
To resolve this, try using the WD Quick Formatter Tool and then select the Factory Default setting to back up your drive. This will remove all the data in your drive.
