New player, display artifacts, missing music after reset.

Well I backed up all the data on the player, sample songs were still on the player despite not showing under the music menu. I reformatted it and then installed the firmware update before restoring the data, everything is back to normal. This leads me to question if the problem lies in the SDMC flash card I included with the player. Are there any SDMC brands out there known for their incompatibility or otherwise has issues with the Clip Zip? The SDMC card is a 32GB Team brand.
