I have a casio lk-210 lighted keyboard that will not format a 1 gb sandisk sd card. All you are suppose to do is insert it and push the format command button and it should work. It responds ERR file, which is wrong because I have have 10 songs in the file. Both the keyboard and sd card arrived only 1 day ago, so everything is new, at least to me.
Thanks,
Moe
