I'm using a 1gb sandisk sd memory card to sync mp3 song on it. THe mp3 songs go on it fine and play on the computer and on the mp3 player ok. The problem is I have about 533mb of space used and have about 400mb of free space remaining. But each time I try to add another mp3 song to the memory card I receive the error message..0x80070052.. Please help..My e-mail [email protected] Card type: sandisk 1 gb secure digital sd card (SDSDB-1024, A10/11, Retail Package).

You probably need to convert the songs to mp3 format to play on your phone. What model phone and what music format are the songs (what are the last 3 letters of the song name, the file extension?)

Well, the most memory from a micro sd card the Sansa mp3 player can take is 2gb, because anything more will freeze up the player because it was not designed to read that much memory. So if you have a 1gb or a 2gb memory card, then you can use them.

The Sansa will only show photos and play videos from its internal memory, not the microSD card. You can put music on the card, but not photos or videos.

Not possible with this unit - it can only read the internal memory of the SD card directly

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.

Try this: disconnect the player from the computer, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

you cant expect all mp3 players to play as many songs as u wnt. each mp3 player has a limit of memory card that needs to be attached. see whats the maximum memory your mp3 player can support. and also see if you can locate all the songs when the SD card is connected to your computer

It is easier to get a SD memory card for it. Drag and drop the music onto the window which represents the SD memory card and then just put the SD memory card into the GPX MP3 player. I have the same MP3 player and it works nice... it was a good deal for the money! Take the savings and invest in a cheap SD memory card and you will be happy.... I was!
:-) Good Luck!

If your device is too full, it wont have enough room to create the music database for the new songs. Move some of your music off of the device onto the memory card. Try to keep about 10MB free for each GB of music you have. You can add to this question for further assistance. Best of Luck.
