お世話になります。上田と申します。
以下の事象についてアドバイス頂ければ幸いです。
【現状と希望】
現状：
家庭用ＤＶＤレコーダで作成したDVD-Rを
Linuxマシンに内蔵されたDVD-ROMでmountしたい。
mount /mnt/cdromとタイプするが”メディアが
見つかりません”と出力される。
希望：
Linuxマシンに内蔵されたDVD-ROMでmountするために
現状の切り分け方法または解決方法のアドバイスを
お願いしたい。
【希望が実現可能と考える根拠】
(1)ＪＦのCDROM-HOWTO.txtに利用可能と記述がある。
(2)linux-usersメーリングリスト内でもideの
転送モードがpioでない場合の不具合しか報告がない
(3)ＲＥＤＨＡＴ８で失敗する事はあるものの
時々mount出来ていた
(4)fEDORA CORE 1でmount出来ていた
【Vineで確認したこと(rootユーザで実施）】
1./etc/fstabの内容確認
2.dmesgの出力確認:
3.容量の大きなCDROMとしてmountできるか？
# mount /mnt/cdrom
mount: メディアが見つかりません
（dmesg確認）
ISO 9660 Extensions: Microsoft Joliet Level 3
ISO 9660 Extensions: RRIP_1991A
cdrom: open failed.
4.コマンドラインからオプションをかえて試す（失敗）
mount -t iso9660 /dev/cdrom /mnt/cdrom
mount -t udf /dev/cdrom /mnt/cdrom
（dmesg確認）
