[debian-users:36113] 複数の外付けIEEE1394HDDの内の一つをファイルリード中に抜くと...
＊メール転送エラーで再度送りました。二度送られてしまったならお詫び申し上げます。
李徹と申します。
Linux上で、複数の外付けIEEE1394HDDからファイルを同時に読み込んでいる途中に、
ディジチェーンで接続された1394HDDのプラグを抜いた時、
接続中のIEEE1394HDDからもファイルが読み込めなくなる場合があります。
（IEEE1394をHDDデイジーチェーンでつなげ、2番目のIEEE1394HDDを抜きました。）
LinuxOS -> PCI bus −＞ IEEE1394HDD（1番） −＞ IEEE1394HDD（2番）
そして、接続していたIEEE1394HDDのファイルシステムがおかしくなり、
マウントし直すか、最悪の場合フォーマットしてやっと、マウントできるようになります。
マウントしようとすると、
# mount -t ext2 /dev/sda1 /mnt/1394
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems
というエラーが表示され、さらに、xconsoleに以下のような,３種類のエラーがでます。
1．attempt to access beyond end of device :マウントし直せばよい場合のエラー
2．unable to read super block : モジュールを再ロードすれば、マウントできる。
3．init_special_inode : bogus inode(0) ：フォーマットすれば、マウントできる。
なぜこのような現象が起こるのかわかりません。
どなたか対処法を教えていただけないでしょうか。
よろしくお願いします。

--------------------------------------------------------------
動作環境は、以下のようになっております。
・Debian Woody kernel 2.4.20
・IEEE1394インターフェイス: ロジテック製LHA1394L
OHCI準拠Texas Instruments chipset
・HDD : Maxtor製5000DV 120GB 7200rpm 、2台
・libraw1394‐5
モジュールをロードして、SCSIデバイスとして認識してファイルの読み書きは正常に
行われます。．
