My sony walkman wont hold music, it always says no data after i put songs on i. i have tried using windows media player

Format it everytime you want to add songs. The little memory module inside gets confused often as to how much data it can hold. So always format it first.

To reformat the NWZ-S545 Walkman follow these steps found on page 92 of the operation guide:

Formatting memory [Format]
You can format the built-in flash memory of the player.

Note:

• If the memory is formatted, all data (songs, videos, photos, etc., including sample data installed at the factory) will be erased. Be sure to verify the data stored in memory prior to formatting, and export any important data to the hard disk of your computer.

• Be sure not to initialize (format) the built-in flash memory of the player using Windows Explorer. If you have formatted with Windows Explorer, format again using the player.

• This function is only available in the pause mode.

1. From the [Home] menu, select [Settings] / [Common Settings] / [Format]. [All data including songs will be deleted. Proceed?] appears.
   
2. Select [Yes]. [All data will be deleted. Proceed?] appears. To cancel the operation, select [No].
   
3. Select [Yes]. When initialization finishes, [Memory formatted.] appears. To cancel the operation, select [No].

To delete files from your mp3 player using Windows Media Player 11:

My Directions:

1. Connect your mp3 player to the computer

2. Open Windows Media Player

3. Click on the icon of your Mp3 player on the left-hand side of the Library

4. Click on the Songs, Tracks, or other Music Folder

5. Find a song or songs that you want to delete

6. Left-click the song once to highlight it

7. Press the “Delete” button on your computer’s keyboard

if it doesn't sync, don't worry just open the folder where the music files are stored on your computer, connect your Sony Walkman to your computer and highlight the music files you want to add to the Walkman and select (copy these files) a windows will open for you to select the place you want to copy to, select your mp3 player and click on copy to copy the selected music to your Walkman

NOTE: if you Sony Walkman has a specific folder for music files, you need to move the songs you copied from your hard drive's music folder to the music folder on your mp3 player for the player to recognize the songs in order to play.

make sure your downloading it to the right folder on the mp3 player its usualy the music folder or you can try and use windows media player here are some instructions for that option.
--**Windows Media Player**--
If you have a large playlist to transfer, you may prefer to do it from your media player, such as Windows Media Player. Once your MP3 player is connected to the computer, open Windows Media Player. Click on the "Sync Music" tab. Drag songs that you want from your Windows Media Library over to the "Sync Music" column to create a playlist. Click the "Begin Sync" tab at the bottom once you have all of the songs on your playlist. This action will sync all of the songs to your MP3 player with one click. Disconnect your device once songs have been transferred by clicking on the "Safely Remove Hardware" icon in the bottom-right side of the desktop tray.

because you formatted your mp3 thru the computer, if your mp3 has an option in its sytem you may format it here. and you should download the songs thru the sonique stage, you can not transfer directly coming from your win amp or windows media player because of different file format

firstly all the tracks you want must be converted into mp3 format. You can get hold off mp3 converter software such as Power and winlame. also all the tracks you want has to be imported into the Connect Player software. you should have a cd that comes with the player, it is similar to iTunes with the iPod. i think you can possibly download it from the sony website. when you have them both convert the tracks into mp3s and then import them into the Connect player. From Connect you will be able to transfer the music across. Hope it helps
