ปรับปรุงเครื่องคัดลอกแผ่นซีดี

ปรับปรุงครั้งที่ 1

• แก้ปัญหาแผ่นธรรมดาอ่านผิดพลาด ด้วยการพยายามแยกแผ่น
  • ถ้าเป็นตระกูล VCD ซึ่งเป็น multitrack ใช้ readcd+cdrecord -clone
  • แต่ถ้าเป็นพวก mp3 ธรรมดา ใช้ dd+cdrecord แบบ normal
• เนื่องจากทดสอบด้วย debian-desktop (etch) เลยต้องเพิ่มฟังก์ชั่นการยกเลิกการเมาต์อัตโนมัติด้วย
• ฝากทดสอบและช่วยปรับปรุงให้ด้วยครับ
