Windows 7: Backup failed error 0x8078002A io device error windows 8 on an external 3Tb drive Page 1 of 2 1 2 > 17 Mar 2012 #1 louwin Windows 7 Professional x64 (Desktop) Home Premium x64 (Laptop) 22 posts Perth, Western Australia Backup https://support.microsoft.com/en-us/kb/952272 failed error 0x8078002A on an external 3Tb drive I bought 2 new 3Tb Seagate Expansion drives model STAY3000300. I tried to "Create a system image" and both 3Tb drives were presented as possible destination discs. I selected one of them and after a couple of messages about preparing and starting the following message was displayed. (same message on the other 3Tb drive as well) The backup failed BIG RED http://www.sevenforums.com/backup-restore/219909-backup-failed-error-0x8078002a-external-3tb-drive.html BAR One of the backup files could not be created. (0x8078002A) Additional Information: The request could not be performed because of an I/O device error, (0x8007045D) The system is Windows 7 64bit and bang up to date with Windows update. The system disc is a OCZ Agility 3 120Gb SSD. Another strange thing is I have been doing backups to another external disc for many months - a 1Tb Iomega portable external. The MAIN BU file is about 26Gb and, yes, all my discs are formated as NTFS so it is not a file size issue. I am not desperate as I have other discs to backup to but I am curious why the backups fail on the new 3Tb external drives?

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 o device error 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 for co
