I've been reading this forum to get an answer on the dreaded error "E000700004: Failed to write to the data to the archive file" but did not get any resolve. I get this error on T10 and T11 when I do a backup to my USB 2.0 external hard drive 120GB which is empty and formatted NTFS. I thought perhaps the drive or external enclosure was the problem so I tried it on 2 other drives and different external USB 2.0 enclosures. They all stop with that error at different points. I was thinking perhaps the USB was the fault so tried other USB ports. Same problem. Maybe on some PC's USB doesn't send the data correctly? USB ports can be under powered. I'm NOT using a laptop though. I was able to send the image to my C drive and then just copy it through Windows to my external USB 2.0 drive. Why would that work if the USB ports might be the problem? My external USB 2.0 enclosure gets it power from the computer ONLY.
