False Ads by 3TB Hard Drives & Microsoft or a test left undone
I need disc image backups and since I use Win 7 Pro 64 bit, I look for the Microsoft Win 7 logo on the HD package. Since my disc image size is about 600GB, I want something that is big and faster than USB 2.0. Yep, there is a WIn 7 logo on the 3TB WD My Book Essential External Hard Drive USB 3.0. box. Since I could get 2 of them for US$250, I bought two. Shock & ****, I could not use either drive to make a WIn 7 system image. Google the error message - formatting issue. But, on the box was "Formatted NTFS for Windows XP, Windows Vista or Windows 7."
Search on Microsoft and find a posting from 2007 that admits to this "rare error." It seems that Microsoft software does not like the 3TB size. Yep, I have the May 2011 KB update that was to fix this issue installed on my system . I should mention that WD is in big denial of any such problem. Tried using USB 2 instead of USB 3, no go. Formatted HD as exFAT, no go in USB 2 or USB 3. Reformatted back to plain NTFS and wonders, able to make system image in USB 3. Then, several days later, I needed a file back that had been securely erased.
Oh, unhappy days. System will display the system image, but try to restore the system image and the computer tells you - unable to find the system image in either USB 3 or USB 2. I had to copy the system image from the WD to a Verbatim 2 TB External HD USB 3 over 8 hours, then use the Verbatim 2TB HD in USB 2 mode to restore the system image. It seems 3TB is a TB too far for Windows 7. You should tested the use of WIn 7 system image on the various 3TB hard drives because that a major reason to buy 3TB external hard drives
