How to decode qr code from SD card?

Im getting an error code 0x80070052 while trying to put music on my SD card. HELP!?

• I got a new stereo in my car that can use an SD card. So I bought an SD card and a converter drive to put music on the card. I was clicking on the songs from MP3 Suite and dragging them to the drive file in "My Computer". Everything was going great when all of a sudden an error code came up that said "error 0x80070052". I was able to get about 111 songs on the card with TONS of room to spare. It says I have 1.35 GB left of memory. So I thought maybe there was a limit to the number of songs I could put on it. So I deleted one of the songs and tried to put a different one on the card. No dice. But I was able to put the song I deleted back on the card. According to the card container info, I should get roughly 350 songs on the card if not more. Whats going on? Should I be able to get more songs? What am I doing wrong? All the connections are on properly and the blue light on the Converter is on. PLEASE HELP!!!

• Answer:

  Try formatting the card and putting the songs back again. But this time try taking 10 songs at a time and making sure they work. You may have a corrupted file in one of your 111 songs.
