Because the SEEPROM contains the encryption keys for the external hard drive, backing up seeprom.bin is critical for data preservation. If the Wii U hardware fails but you have a backup of your USB drive and the seeprom.bin file, it is theoretically possible to decrypt the data on a PC or move it to another console (though the latter involves complex key manipulation). otp.bin seeprom.bin
