Internal hard drive wont transfer to Xbox external hard drive

You are using transfer, which is to move the contents of your internal hard drive to the external hard drive instead of copying, you do not need to manually delete the contents of the internal hard drive (because they are already on the external hard drive).

As an idea for xbox one hard drives because they are internal and not external try plugging in an external drive to save or transfer all important games to external hard drive and leave not so important games onto internal drive
that way you can take them anywhere and not have hard drive failures with xbox one.

The data transfer cable will not plug into the Halo hard drive. The transfer cable evidently cannot tranfer dater from a console with an internal hard drive to another console with an internal hard drive. I will have to transfer my data to an older external
hard drive, then transfer it to the Gears console. I just hope I do not lose any data.

The external hard drive was around 20% full. After the I formatted the external hard drive it went down to 0% as everything was uninstalled. Thing is i tried transfering Battlefield 1 from the internal hard drive to the now empty external hard drive and
it started transferring. Battlefield 1 was one of the games that just stopped installing/transferring when i wanted to move from the internal to the external hard drive so i might of fixed the problem. Now i am just concerned that the games that were uninstalled
will not have anyting saved and i will have lost everything.

No you can only transfer content to flash droves internal 360 hard drive or external hard drives configured to be used on a 360.
