kprobe 並不建議用 DVD-ROM 來測試PIPO

DVD-ROM drives do not respond to the read-speed commands from
Kprobe, so they will always scan at full speed. This is especially bad for DVDR scanning.

DVD-ROM drives do not appear to report the same types of errors as C1-C2 and PI-PO as the burners do. We do not know what they are reporting, but there does not appear to be any predictable relashionship between what gets reported on a ROM drive and what gets reported on a burner.

Many people do use ROM drives for scanning errors, and this is certainly better than not scanning at all.
小弟英文不是很好........
DVD-ROM 不會回應kprobe中的讀取速度，所以DVD-ROM是以全速來測，這對測DVDR來說甚壞。

DVD-ROM 測出的錯誤格式(C1-C2和 PI-PO)與燒錄機並不同，我們不清楚DVD-ROM測出什麼，但並不表示DVD-ROM與燒錄機測出來的結果沒有任何關聯。

有測有保佑.............

小弟對同一染料測試[LEADDATA01]不確定是同一版面
用NEC 2500A 1.07v2 Dual Layer Bitsetting Beta 5的韌體
Liteon DVD-ROM SOHD-167T測

某位大大用Liteon DVDR測

結果差不多,不過我覺得是特例.我測的其他片子分數通常都不是很好看,但曲線應該不會差太多
V-Star +R綠色蚊香片

DVD-ROM測分數偏高,不過總比瞎子摸象好.......
