Windows 7 Backup produces errors 0x8078002A, 0x8007045D

I purchased a SeaGate Desk 3TB USB external Harddrive to provide back up for my Windows 7 files. I have tried both various SeaGate backup SW as well as the Windows 7 back up routine. I have spent days trying to find a successful resolution to the infamous 0x8078002A and associated 0x80070045D error messages. I have tried just about every fix I could find on the internet and various forums to no avail. I finally came upon one discussion that appears (I repeat - appears) to identify the root cause of the problem.

Problem:
When using Windows 7 Backup and Restore with a 2.5 TB or 3.0 TB drive, the backup fails with an error code of (0x8078002A).

Cause:
This problem is caused by an issue with the Windows 7 Backup and Restore utility when using drives with 4K Logical sector sizes, which are found on WD 2.5 TB and larger external drives. This is different from an "Advanced Format" (AFD) drive which use 4K physical sector sizes. AFD drives should not cause this problem.

 

IF I understood the "solution" correctly - it appears I would need to re-partition the SeaGate drive so that the logical sector size matches the current windows 7 default.

 

I received a response from SEAGATE Support which solved the problem. They provided detailed steps on bascially how to erase and repartition the 3TB external hard drive with GPT format. Once that was done the GoFlex Desk 3TB drive backed up my system with both an image as well as file copies. I was able to use the Windows 7 Backup system - desired because it also created a disc Image of my system.

 

All the other "fixes" I tried produced no results - this worked!!!!!

I am facing exactly the same issue and would like to use Windows Backup too. Could you elaborate on the solution you received from customer support?

Thanks!

How did you contact Seagate Support.  Right now none of the Support links work for me.

Windows 7 backup experiences that issue with all 4K drives. There's no fix available from Microsoft, but the issue is expected to be fixed with Windows 8.

Is Seagate going to release a fix for their drives that corrects this issue like Western Digital has or do I need to return my Seagate drive for a 3TB drive that is compatible like a Western Digital?

Have you tried to Restore from the Windows System Image on the Seagate yet?

 

I have a  1T GoFlex Home connected to my home network. 'Genearally speaking it has been reliable ... a little quirky, but it works

 

My personal PC is an Asus laptop wiht Win 7 64

 

Creating the System Image was farily stratight forward. However, when I try to restore, Windows asks for the device share location in the ususal "\\share\drive\" format.

 

Unfortunately, no matter what I enter, Windows 'can't find' the drive.

 

According to file manager, the share address is \\GOFLEX_HOME\GoFlex Home Backup\.

Since Windows 7 has trouble recognizing the 4096 kilobyte allocation format, just use Windows 7 itself or a program of your choice to change the partition on the drive. You can delete the whole partition - but then you lose Seagate's include programs - or split the partition and use only a specified portion of the drive. Remember to assign a drive letter to the new partition, if the program you use doesn't do so automatically. Reformat the second half of the drive using ex-Fat instead of NTFS. When formatting, make sure the allocation units are 512 (which is what Windows will recognize). Then you can perform your backup on this partition without any further error. Piece of cake. Don't need a fancy program to do this though...Windows 7 Home Premium did it all.

Re: Windows 7 Backup produces errors 0x8078002A, 0x8007045D

Reformating to eXFAT will allow for backup of "user files" using windows 7 backup and restore but it will not allow for a "System Image" so you can restore your OS in the event of a catastrophic breakdown.  I believe that most users will want to be able to restore their entire system if it crashes.  Seagate needs to come up with a fix for this.  They should not say the Go Flex 3TB drive is compatible with Win 7 if it will not preform a simple system backup.  Microsoft is a bit at fault as well for knowing that newer drives were going to be 4096kb and not 512b.  If they can fix this for Win 8 then they surely can make a patch for Win 7.  After all Win 8 is going to able to run on Win 7 machines.  Right?

Hey Roatary_Ed would you mind sharing those "detailed steps" with the rest of us who are having the same problem? What exactly did Seagate support tell you to do? I tried simply changing my 3TB external drive to GPT and that did not fix the problem. I must be misssing a step....

Well, same here

I reformatted at GPT (two partitions, one 2TB, the other 1TB).

Wint 7 backup still does not work.I tried backup up to first the 2TB partition and then to the 1TB partition and got the same error both times.I still get 0x8078002A and 0x8007045D.

 

<quote>

One of the backup files could bot be created (0x8078002A)

Additional information:

The request could not be performed because of an I/O device error. (0x8007045D)

</quote>

 

I reformatted as MBR and only used 2TB (because it's MBR) ... remaining stayed unallocated. Same error.

 

I'm at a loss. I cannot think of anything else to try. Is this just a Seagate thing. Will it work if I get a drive from another vendor. I'm willing to try that, but hoping someone might comment first. Has anyone been successful with another drive that they can recommend.
