Step #3 in comment 5 above works for me: 3. 'sudo eject -i off' So it seems that the drives are locking after eject for some reason? For me, this happens on Lubuntu 12.10. I can insert one CD and eject it, but then the drive is unusable again until I issue the command above.
It only happens with my DVD reader (/dev/sr0), not my DVD writer (/dev/sr1). lshw taken after issuing the command above, both drives are in fact empty. *-scsi:0 physical id: 1 logical name: scsi0 capabilities: emulated *-cdrom:0 description: DVD reader product: DVD-ROM GDR8161B vendor: HL-DT-ST physical id: 0.0.0 bus info: scsi@0:0.0.0 logical name: /dev/cdrom logical name: /dev/dvd logical name: /dev/sr0 version: 0040 capabilities: removable audio dvd configuration: ansiversion=5 status=nodisc *-cdrom:1 description: DVD writer product: DVD-RW GSA-H11N vendor: HL-DT-ST physical id: 0.1.0 bus info: scsi@0:0.1.0 logical name: /dev/cdrom1 logical name: /dev/cdrw1 logical name: /dev/dvd1 logical name: /dev/dvdrw1 logical name: /dev/sr1 version: JG03 capabilities: removable audio cd-r cd-rw dvd dvd-r configuration: ansiversion=5 status=nodisc -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/875543 Title: can't eject cd rom : Inappropriate ioctl for device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/875543/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
