CD mount problems

[CheatMasta]

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

umount -l /media/cdrecorder

also

man umount

will show you which other options you could try if the above does'n work.

Thanks, but this problem recently fixed itself. I have no idea why, but now CD's mount and umount just fine. Thanks anyway
