Please help me as i tried the following but still the problem exists: 1. Stripped the drive to 2Tb 2. Stripped the drive to 1Tb 3. Formatted the drive in Windows to NTFS Laptop Info: Windows 7 Professional 64-bit i5 CPU, 2.53Ghz 4Gb RAM Thanks, Grr

Have you run chkdsk to check the USB HDD?

Hi, If there is no error after the disk checking, please temporary disable antivirus, update BIOS and device drivers such as hard drive from computer manufacturer’s website to check the result. If the issue persists, I suggest you boot in Safe Mode, and clear the temp folder. Delete every files that can be deleted. C:\Users\%username%\AppData\Local\Temp In addition, the following threads would be helpful as well. http://social.technet.microsoft.com/Forums/en-US/itprovistaapps/thread/7b64e871-71be-4c5d-a4a3-502744da978b http://social.technet.microsoft.com/Forums/en/itprovistaapps/thread/9e5b22f1-8fb3-4d70-8f79-b92c7dc6e840 Thanks, SimidaPlease remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.

Still nothing seems to be of help. 1. Formatted through windows 2. Volume Shadow Copy is set to Manual 3. No Security software installed 4. Chkdsk for the external drive reports no error 5. Tried using another Disk, another cable, another USB port- still same error with 3Tb drive. I researched again and found that a lot of W7 users are complaining of this issue. It looks like there is a bug in W7 which is causing all this trouble. Could someone open a bug report with Microsoft? Thanks, Grr

Hi Grr, Thanks for your reply. I have checked this issue through our internal channel, it is not a bug. This can be the communication problem between the USB device and the computer. Let's reinstall USB controller to check the result. I would like to verify if backup to other device will work. Based on the current situation, I suggest using another external hard drive less than 3TB or local hard drive as the backup location. You can re-configure the backup settings. In addition, please also run the disk defragment to check the result.

And the system image was successful on 2 different External WD drives of capacity 1Tb & 2Tb, respectively. Thanks, Grr

Hi Grr, It seemed the issue is caused by too large space of the External WD drivers. I suggest creating partitions on 3TB External WD to check the result. Also, reformatting the External WD to check the result.

HI, I have the same problem, but with a SEAGATE FA GOFLEX DESK 3TB drive. the backup from windows 7 fails with an error code 0x80078002A. i followed the suggestions in this thread without success, and also reducing the main partition to below 2.2TB didn't help. the drive does not us gpt tables, as its intended to be used with winxp as well, and seagate seems to have implemented some workaround for the3TB size. could this be the problem?

I have this problem. System is a Dell XPS 435T, Windows 7 64bit Home Premium. I have never had any success with performing a system image backup to my Seagate 3TB USB drive. The request could not be performed because of an I/O error. Error code: 0x8078002A The drive is fine because I can store all kinds of files in it: big or small. Please Microsoft, help us out!

I'am also having this same problem. Just got a new Seagate FA GoFlex Desk, 3TB Drive. Have HP with AMD Dual Core, 4GB RAM that was Vista 64. Upgraded to Win 7 64 pack 1. Wanted to create a new backup image. Errors: - one of the backup files could not be created: 0x8078002A - because on an I/O error : 0x8007045D Both of these errors happen at the end of the backup process. New drive appears to be working fine with respect to everything else. Microsoft, Seagate & WD. Appears to be more than an isolated problem. Someone please help!!

Please create partitions on 3TB Drive http://support.microsoft.com/kb/2510009 Regards, L.S
