Song Formats for Mp3 Players Explained
By Tha Mp3 Doctor
I have seen quite a few threads around Fixya in which the stated problem is that the Mp3 or Digital Audio Player will not load the songs; will appear to load the songs but will not actually play them in the Mp3 player once disconnected from computer; will skip the songs on the player, or show only “0:00” for file length; songs “disappear” all of a sudden (although this particular problem can be caused for many reasons not covered in this article); your store-bought/burned/ripped CD’s will not load into your Mp3 player; or get the error message “File Format Not Supported.” All of these problems occur because the user is trying to download a song format that the player does not recognize. Every music file is in a certain format. The most common music file formats are Mp3, WMA, AAC, WAV, RA, etc. Each Mp3 player only recognizes a certain number of these formats. Every Mp3 Player is different. You will have to check your Mp3 player’s product specifications (specs) or user’s manual to find out which formats your particular Mp3 player recognizes. When you try to download or sync the wrong file format, you will get one of the errors that I mentioned above.
Or, it could be a "formatting" issue:
There are two ways to format an Mp3 player - one on the computer itself, and one in Windows Media Player. Both methods will end up erasing all the songs on the player, but the player will be "good as new" after that. Sometimes reformatting in this manner will override the player's native formatting and cause problems - this can be reversed in most cases by updating the player's firmware. Firmware upgrades are available from most manufacturers' websites.
WARNING: The following procedures will erase all songs on the player.
Check if the file system is NTFS. If yes, format it to FAT or FAT32. - Connect player to computer, double-click my computer, right click on icon of mp3 player and select format. This only applies to Windows-based computers.
You can also format the player in Windows Media Player itself:
Connect your Mp3 player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "name of Mp3 player here 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
