MP3 players can only play music files in mp3 file format.You can download mp3 music files from the Internet toyour computer and then copy them to your MP3 player.For your CD collection, you need to convert your CDs tomp3 music files onto your computer or download them from the Internet and thencopy them to your MP3 player after you have connected the USB cable tothe MP3 player and the computer. You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.Click on this link for instruction on converting musicfiles to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files
try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .
it sounds crazy .
Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.
Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.
It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).
beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.
This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.

Try a different USB cable instead. Most likely a pin in the USB cable your are using is faulty and because of that your computer can't detect your player as the pin required for your computer to detect it is faulty. You can take a look at http://mympx.org for other users who have similar problems as well.
You may have a defective MP3 player. I had one and had to send it back (it wouldn't show up on my laptop, and it manifested a graphical problem). If the company you bought it from is reputable they should refund you. ALWAYS be sure to buy expensive items like these ONLY from reliable sellers, even if they're a little more expensive than others!
does the pc recognise the device when you connect it? if so you should be able to access the drive which contains the mp4 folders. very rare that they will be kept on the top level of the drive. navigate to the folder on the device which would normally contain your mp4 files and drag files from your storage backup folder direct to the device. checking that you have the files in the correct format ie: .mp4 you should find they play fine. try to avoid wherever possible using the acctual software which controls your music device as they are prone to complications.
I have the nwz-a816 and if have had this issue a couple of times... It seems to give me that message on songs I have downloaded from Napster... I just connected it to the computer that the Napster application is on and it corrects this problem... Hope this helps...
it's the 4GB NWZ-A816PNK Walkman version? connect usb to your computer wait for the connect sound open my computer look for removeable drive right click on it and explore go to music folder open your library drag w/e songs u want into the music folder
Try this and let me know. First unplug the unit. Plug it back in. When you first push the power button, you should hear 1 click followed by another withing 5-20 seconds. My guess is that you don't hear the second click. Am I right?
