Do not disconnect your Walkman from your computer when transferring data between the Walkman and the computer via USB. Doing so may result in loss of the data being transferred and data on the Walkman.

Do not turn on, restart, wake up from sleep mode, or shut down the computer with your Walkman connected to the computer via USB. Doing so may cause the Walkman to malfunction. Disconnect the Walkman from the computer before conducting those operations.
