[plamo:29057] Re: cdrecord BLANK mode

こじまさん，

間隔が空いてしまい大変失礼致しました．

> せばいいはず．

はい．下記，balank=fast で消去できることを確認しました．

bash-3.2# cdrecord blank=fast dev=1,0,0 -vv

しかし，その後cdrecord dev=1,0,0 -vv speed=4 -data plamo-4.22_02.iso
で書き込みを試みますが，途中までは書き込めるのですがエラー終了してしまし
ます．(下記ログ１)

Sense Key: 0x3 Medium Error, deferred error, Segment 0
Sense Code: 0x10 Qual 0x00 (id crc or ecc error) Fru 0x0

dmesg も観察していますが，有用なメッセージは表示されていないように見受け
られます(?)．

消去の問題なのか書き込みの問題なのか，それろも両方関係しているのか．．．
blank=all でエラーが起きるのも良く分かりません．

# CD-R に書き込みできる様になりましたので現状困ってはおりません．
# 書き込みテスト用CD-RWを購入したのに有効利用出来ていないのが．．．

(ログ１；blank=fastで消去後の書き込みエラー)
# cdrecord dev=1,0,0 -vv speed=4 -data plamo-4.22_02.iso
