I have just purchased a Buffalo HD-LBU2 3Tb hard drive which will not back up Windows 7.
Windows back up returns a message that “One of the backup files could not be created. Error Code 0x8078002A I/O DEVICE ERROR 0X8007045d”
I am running Windows 7 SP1 and both my System drive and the external drive are formatted as NTFS
Thanks for your help guys. The Problem has been solved by reformating the external drive with GPT partition style which gave a 512 byte file sector size instead of the previosly factory MBR partition with 4096 byte sector size.
The programme I used was Diskfomatter light which was included on the original drive by Buffalo but which I had not realised contained alternative formatting styles for their Drives.
