I recently tried to led mod my slim egg and failed and half assed reassembled it, it is not functioning rn however I believe it should once reassembled properly so I got a new fat rgh and have transferred the content folder from old hardrive over to new 2tb external however says there is no more room when it should only have used a quarter of the storage
(Formatted 2tb in the 360 settings and showed as 2tb) and ideas on how to fix or what went wrong
