It's probably stupid to stay with ata(4) driver with the ahci mode, isn't it? But with ahci(4) driver you can't burn with burncd(8) and cdrecord just fail and break an blank cd for nothing. I guess this is the correct behavior when trying to use burncd(8) / cdcontrol(1) : markand@Melon ~ $ burncd msinfo burncd: ioctl(CDIOREADTOCHEADER): Input/output error markand@Melon ~ $ cdcontrol info cdcontrol: getting toc header: Input/output error cdcontrol: Input/output error But why the optical drive is only affected? If I use ata(4) driver even with ahci mode set in the bios, why the hard drive works pretty well? Kind regards, -- David Demelier
