    CD mount problems


    Hi, I'm running CentOS 4.4 and recently I've been having trouble trying to mount/unmout/eject the cdrom.

    When I tried to mount the cd, I got this message:
    "/dev/hdc: Input/output error
    mount: block device /dev/hdc is write-protected, mounting read-only
    /dev/hdc: Input/output error
    mount: /dev/hdc already mounted or /media/cdrecorder busy"
    When it finally does mount, I can't unmount, as it gives this error message:
    "umount: /media/cdrecorder: device is busy
    umount: /media/cdrecorder: device is busy"

    Even though it isn't in use. Trying to eject gives a similar message:
    "umount: /media/cdrecorder: device is busy
    umount: /media/cdrecorder: device is busy
    eject: unmount of `/media/cdrecorder' failed"
    or
    "eject /dev/hdc failed!"

    It does this for both root and normal user. Any help would be appreciated.

    try
    Code:
    umount -l /media/cdrecorder
    also
    Code:
    man umount
    will show you which other options you could try if the above does'n work.
