[linux] CDやDVDをddやdvdbackupを使いiso形式でバックアップ

今まではCDとDVDをiso化する際に、ddを使っていた。このたびDVDをバックアップする際に、ddではリードエラーが出たのでdvdbackupを使った。そのときの記録。

まずはいつもどおりddでiso化を試みるが、入力出力エラーが出て取り込めない。

$ dd if=/dev/cdrom of=cdrom.iso
dd: reading `/dev/cdrom': 入力/出力エラーです

rootになって、カーネルログをチェックすると以下のような感じ。セクタの読み込みに失敗してる。これは多分コピーブロックだろう。

エラーメッセージを手繰ると、どうやら"READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION" が出るのはコピープロテクトされたDVDをddしようとしたことが原因で、これを回避するには、一回DVDプレイヤーで再生して、その後に再度ddすればよいらしい。もう一つのエラーメッセージ"Error: Illegal request"で手繰っても何も出てこなかった。

If you encountered "READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION" error, it means the protected dvd is locked. Open the movie with a player, play a little and pause/stop it, then run CDSpeed again.

MPlayerで1分くらい再生。正しく再生されることを確認。

$ mplayer dvd://1

その後にいつもどおりddでiso化する。

$ dd if=/dev/cdrom of=cdrom.iso

まずは引数とオプションの確認。ddとオプション指定の方法が似ている。取りあえずのところは、-M:完全バックアップ。-i:入力デバイス、-o:出力ディレクトリの認識だけあれば事足りそう。

$ dvdbackup -h
Usage: dvdbackup [OPTION]...

  -h, --help         display this help and exit
  -V, --version      display version information and exit

  -I, --info         prints information about the DVD
  -M, --mirror       backup the whole DVD
  -F, --feature      backup the main feature of the DVD
  -T, --titleset=X   backup title set X
  -t, --title=X      backup title X
  -s, --start=X      backup from chapter X
  -e, --end=X        backup to chapter X

  -i, --input=DEVICE       where DEVICE is your DVD device
                           if not given /dev/dvd is used
  -o, --output=DIRECTORY   where directory is your backup target
                           if not given the current directory is used
  -v, --verbose            print more information about progress
  -n, --name=NAME          set the title (useful if autodetection fails)
  -a, --aspect=0           to get aspect ratio 4:3 instead of 16:9 if both are
                           present
  -r, --error={a,b,m}      select read error handling: a=abort, b=skip block,
                           m=skip multiple blocks (default)

  -a is option to the -F switch and has no effect on other options
  -s and -e should preferably be used together with -t

で、バックアップ開始。失敗。

$ dvdbackup -M -i /dev/cdrom -o cdrom
Error reading MENU VOB
Mirror of Title set 1 failed
Mirror of DVD failed

"dvdbackup Mirror of Title set 1 failed"で手繰ったが何も出てこない。

失敗したので、カーネルログ確認。エラー内容はddを使った場合と同じっぽい
