I have and RCD510 which i use the sd slot for my music.
In the the past i just used my crappy acer laptop and everything was fine.
But i have just purchased the new iMac and now putting the music on has messed everything up.
Basically when on my sd card i organise all the music under Artist so for instant i click on Drake and the songs are duplicated on there but only one of them will play the other one says that it cant be read.
So i have now plugged in the sd card to my computer to see if i did copy them twice and there is only showing one set of songs
checked the file type and its mp3.
So why do i have this other set of song on a format that cant be read???
