Ghost, Sorry but it is not possible to recover the lost space. If your player has gone from 1GB to 474 then it is most likely a 512MB chip that has been hacked to read as 1GB. If you have formatted your player you have removed the hack and now your player is showing it's true size. You need to open your player and check the serial number of your chip against this list
