Cannot eject CDROM with bad media inserted - IO error

[Bartłomiej Żogała]

Binary package hint: eject

I have media which cannot be read
[ 7707.154066] Buffer I/O error on device sr0, logical block 1024
[ 7707.154070] Buffer I/O error on device sr0, logical block 1025
During read error I cant eject media even with eject command.
I know about /proc/sys/dev/cdrom/lock and /proc/sys/dev/cdrom/autoclose variables but they need to be set before inserting media, and only way to fast remove is hard reset system. Eject should have --force option not as a feature but as solution of critical bug - in my case Cdrom gave strange sound and there was a risk it will brake.
