it doesn't see the hdd i plug in from usb

Could be any number of issues. Try these:

Try different USB ports. Your external must be USB 3.0 or higher at at least 128GB in size.

If that doesn't work, make sure your drive is formatted correctly. ( My games & apps > Manage > Storage devices)

Is this for Xbox One? Xbox One X/S? Xbox One Series X/S?

Does your PC or laptop recognize the drive when plugged in? Have you tried other cables if able?

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

I would like to confirm, are you on Xbox or PC?

This will determine what are the next steps we have to perform.

Remove your HDD, try to use your console. If it doesn't freeze then it's your HDD. If it still freezes, remove all devices from your 360. USB drives, Kinect, HDD, unplug everything. Try to use it then. If it freezes then, then your console needs to be sent
in for repair. If it doesn't, plug in one device at a time testing to see which device causes it to freeze.

Please hard reset your Xbox One. Then start it up again and re plug the External HDD in the back USB 3.0 port. If that doesn't work please check the format of the external HDD and check to see if the USB cable is 3.0. I heard many people say that Western
Digital are still giving out 2.0 cables

I tried all that but the main problem is there is nothing in the HDD to delete.... Everything said 0KB... Clearing the cache doesn't help and I tried to do anything with the HDD and nothing... I was able to use a USB...

Plug in USB then format USB to Xbox.

Connect to net and download update.

Finished with update download profile.

Move profile from USB to HDD.

(My problem is I cant move my profile over just like I couldn't download it into my HDD in the first place)

Problem should be fixed now.
