There was a problem with the PS3 system writing data to the external storage media. Solution: Check that the connection between the external storage device and the PS3 system is secure and that any connecting cables are not damaged. Try transferring data from a PC to the external storage device to ensure that it is functioning correctly. If your PC is also unable to write to the external storage device, the device may need to be replaced.
