    System image backup issue

    When I tried to make a system image backup on my 2 TB USB drive, Windows 7 Backup failed with the message "One of the backup files could not be created. (0x807802A) ... The request could not be performed because of an I/O device error. (0x8007045D)"

    From a quick web search, I gather that this is a known issue caused by the large USB drive's having a larger sector size (4 Kilobytes) than Windows 7 Backup can handle (512 bytes), and that possible solutions include reformatting the USB drive (which I would rather not do) and using some other backup/restore utility that can work around the issue ... any recommendations?

    One alternative is Macrium Reflect, free or pay-for version; it doesn't care what the sector size is for NTFS or FAT external devices.
