My System: Windows 7 - 64bit I have previously had a 2TB seagate drive that worked perfectly, I updated to the newest 3TB drive (same model,etc.) After several failed attempts usually showing error 0x8078002a I began to research this forum and others, so far nothing has worked. I have done the following in my pursuit of a good backup. One other noticeable issue is that is seems to generate this error while writing the "System Image" which I believe is the last step of backup? 1.reFormatted drive - NTFS 2.Updated bios and all drivers and windows updates on computer 3.Turned shadowing to auto, manual, auto dealyed write, started, stopped, etc 4.Rebooted and attempted to backup immediately after 5.Trouble shoot with SeaGate (no help as they say it should work?) 6.Applied HotFix http://support.microsoft.com/kb/982018 7.Still Looking for help from MicroSoft (currently) There are a few post here with this same issue but no resolve seems to be in place. Please advise if you may have some direction for me to go next. I assume it is a larger drive issue as the 2TB drive works how it should. Chaze Karanick

If you had done some research you would have learned that unless you are using an Apple Intel computer with EFI, you cannot have a 3TB boot disk. See info below: Using High-capacity Hard Drives How you plan to use your high-capacity drive will determine the steps you must take to ensure access to the full capacity. As a Data Drive A data drive greater than or equal to 2.2TB requires an operating system that supports long LBA addressing, such as Windows 7, a GUID partition table (GPT) and HDD drivers that support 2.2TB drives. As a Boot Drive In addition to the requirements for a data drive, a Windows boot drive requires an EFI (Extensible Firmware Interface) BIOS and a 64-bit version of Windows Vista or Windows 7. Linux does not require an EFI BIOS. As a USB Drive USB drive enclosures must be configured to work with high-capacity drives so it is important to confirm with the manufacturer that the enclosure will support capacities greater than 2.2TB. The enclosure may require a driver or firmware update to support the larger capacity.

Hello ChazeKaranick, Is the drive Running 4k native or 512E mode?Thanks, Darrell Gorter This posting is provided "AS IS" with no warranties, and confers no rights.

Hello Rick Dee, Actually there are number of models from HP and Dell that support UEFI, they default to using MBR but there is a firmware option to boot from UEFIThanks, Darrell Gorter This posting is provided "AS IS" with no warranties, and confers no rights.

Hi Darrell, Thanks for your input. The drive from Seagate is a 3TB GoFlex Desk usb 2.0/3.0 - It is 4K native from what I am told by Seagate. It appears that software such as Acronis may be able to write the system image to this drive from what other post I have seen, however I am sincerley hoping to use the WIN7 Backup because of long time trust in it. The drive itself can be used to backup folders, drag and drop, etc. Thanks again and I will look for any input you might have. -ChazeChaze Karanick

I have been searching the internet for several months and all I ever find is references to Apple Intel computers and Intel Itanium computers.

Hello Rick Dee, HP Eltebooks and Probooks should support this, open the manuals and look for bios option to boot UEFI. I am not sure HP supports it, I did open one of their manuals and it shows an UEFI option. Dell R610, R710, T410, T710 should support this. Most of the Intel Motherboards in these lines have the ability *55*, *58*, and *57*, probably want to check the manuals on the Intel site, now if these are in OEM machines, the OEM may or may not expose the option in the BIOS to boot from UEFI. Intels Sandy Bridge chipset should support this as well.Thanks, Darrell Gorter This posting is provided "AS IS" with no warranties, and confers no rights.

Hello ChazeKaranick, Look towards the bottom of the article you referenced http://support.microsoft.com/kb/982018 4K native is not supported, and that is why the Windows backup is not workingThanks, Darrell Gorter This posting is provided "AS IS" with no warranties, and confers no rights.

Food for thought if the updated info from Seagate matters to my issue: Update: Seagate offered some clarification to the paragraph above. Internally the 3TB drive uses 512-byte sectors, however the GoFlex dock emulates a 4K drive to allow for a single 3TB partition to be created in Windows. Thanks again Darrell.Chaze Karanick

ChazeKaranik so does all this still mean we cant use out 3TB seagates to run backups of windows??? i'm not as techinically brilliant as most of you seem to be here. thanks!

Any resolution to this issue yet for 3TB drives? I'm getting the 0x8078002a error on my attempts at creating a system image. 3TB drive, WD.

Hello Tim_Sa, Reference the article http://support.microsoft.com/kb/982018 4K native is not supported, and that is why the Windows backup is not working So check with Western DigitalThanks, Darrell Gorter [MSFT] This posting is provided "AS IS" with no warranties, and confers no rights.

Not sure if you found the solution or not, but in case anybody stumbled across this thread... I also posted this on a similar thread regarding the same failure with Windows Backup and 3TB drives. Here was the solution: I would also like to add a solution that I found that has worked for my 3TB WD Elements drive. Out of the box this drive did not work with Windows backup at all. WD support actually came through for me on this issue and pointed me to the following solution: http://wdc.custhelp.com/app/answers/detail/a_id/6618/session/L3RpbWUvMTMxMzUzNzc5My9zaWQvT1hrMSpJQms%3D Basically it consists of formatting the drive with their external drive formatting utility in "Factory Default" mode rather than XP-Compatible mode which (ironically) is how the drive ships. After performing the format, the drive works fine with Windows backup in both Windows 7 and Windows Server, but is incompatible with Windows XP. In my case, this is an acceptable compromise. This is how the drive appeared out of the box: C:\Windows\system32>fsutil fsinfo ntfsinfo H: Bytes Per Sector : 4096 Bytes Per Physical Sector : <Not Supported> Bytes Per Cluster : 4096 Bytes Per FileRecord Segment : 4096 This is how the drive appeared after the "Factory Default" format: C:\Windows\system32>fsutil fsinfo ntfsinfo H: Bytes Per Sector : 512 Bytes Per Physical Sector : <Not Supported> Bytes Per Cluster : 4096 Bytes Per FileRecord Segment : 1024 Finally, I should point out that this utility will probably not work for drives from manufacturers other than Western Digital as it scans for WD drives specifically on launch and is likely working directly with their drives' firmware. That said, I do believe this should cover all WD drives 2.5TB and larger to correct this issue.

Hello CoreM, Do you have SP1 or the update in KB982018 installed? I was expecting to see the physical sector size as well. Can you right-click on the drive in Disk Management and choose properties, then the volume tab What does it say under Partition Style?Thanks, Darrell Gorter [MSFT] This posting is provided "AS IS" with no warranties, and confers no rights.
