I have an imac Rev A, 64 Mb , os 8.6. I have recently burnt a bunch of mp3's onto a Maxell CD-RW74 disc. it seemed to work fine,But, the other day I put the cd in the imac's cd rom and it asked me to format it or eject. I chose eject then put the CD in the burner I burnt the cd with( USB Que Drive) and the icon showed up on the desktop and all the files were there when I opened it. But it still does not work with the imac cd-rom. Does anyone know why this may happen?
