Windows 7 backup to 3TB Seagate external drive got 0x8078002A error [migrated]
- by Zhang18
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!
