The PS3 system is unable to read the system software update file on a game disc or an external media device, such as a USB drive or a Memory Stick Duo. Solution: If updating using a game disc, make sure the disc is clean and free of scratches. If the disc has deep or excessive scratches, it may need to be replaced. If updating using external media, download the system software update file again or try another external media device.
