To delete abnormal data from the built-in flash memory
If “CANNOT PLAY,” “EXPIRED,” “FILE ERROR,” or “MG ERROR” is displayed, there is a
problem with all or part of the data stored in the built-in flash memory.
Please follow the procedures below to erase data you cannot play.
1 Connect your Network Walkman to the computer, and start the SonicStage software.
2 If you have already specified the data with problems (such as expired songs), erase the data
from the Portable Player window of the SonicStage software.
3 If the problem persists, transfer all data without problems back to the computer using the
SonicStage software while your Network Walkman is connected to the computer.
4 Disconnect your Network Walkman from the computer and then format the built-in flash
memory using the FORMAT menu (page 34).
