Everything on my external hard drive was deleted and now it says %100 full

The Xbox hard drive is garbage, load everything on an external hard drive and your problems solved. I had my hard drive 50% full then it wouldn't do anything. Now with every single thing on an external is actually works correctly the way it should work.

lol you can add external drives. i have a 1TB external. its about 75% full and everything is on it. my internal HD is 100% free. You can delete games and reinstall them later as well if you can't buy another drive. having too many games is a good problem
to have

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.

Thanks, but can the drive be formatted without the 360 deleting everything that's already on my external hard drive, or will I just have to rebackup everything after the 360 deletes it and formats it?

The thing is, the load is always 100% and it will not let down below when nothing is going. External drive, with everything on it (60% full on internal) will make the hard drive run down to 40% allowing more room and a quicker launch. This solves it all.
The power thing is temperary.
