ฉันมีอิมเมจ ISO 733MiB ซึ่งฉันพยายามเขียนลงแผ่น CD-R ฉันมีดิสก์ CD-R สองแผ่นจากผู้ผลิตหลายราย ด้วยดิสก์ CD-R แผ่นแรก (TDK) กระบวนการเบิร์นล้มเหลว แต่การใช้แผ่น CD-R (EMTEC) แผ่นที่สองก็ประสบความสำเร็จ คำสั่งที่ใช้สำหรับการเผาไหม้คือwodim -v speed=1 dev='/dev/scd0' -sao -overburn /home/martin/Downloads/linux.iso
พยายามไม่สำเร็จ:

ความสามารถในการโอเวอร์เบิร์นขึ้นอยู่กับสารตะกั่วใน CD-R / CD-RW เพียงอย่างเดียวหรือไม่? นอกจากนี้แนวคิดใดที่"หมวดหมู่เบต้าต่ำ (B-) (4)"และ"หมวดหมู่เบต้าสูง (A +) (3)"หมายถึงอะไรในส่วนข้อมูล AT-CD ATIP?
