I've noticed that I have problems after I mount the CD: the button on the CD-ROM doesn't eject the tray, but 'eject' command works. I get 'ioctl: Input/output error' but the tray opens OK.
Opening and closing the tray w/o mounting works all the time - with the hardware button and w/ 'eject', w/o any errors.
That's obvious. You have the same effect on any other OS, too.
Sorry, I used an inappropriate description of the issue: after mounting *and unmounting*, the button on the CD-ROM is dead.
I can confirm this behaviour. The error occurs only after the drive was in use somehow. This may be mounting and unmounting the drive, playing a movie using vlc (which does not actually mount the drive if I understand correctly), or ripping a CD using cdparanoia.
Cheers, Norbert
I put the data CD, close the tray, try to mount it, but [karol@white ~]$ sudo mount /dev/sr0 /media/cd/ mount: /dev/sr0 already mounted or /media/cd/ busy It's definitely not mounted, let's try again [karol@white ~]$ mount | grep sr0 [karol@white ~]$ sudo mount /dev/sr0 /media/cd/ mount: block device /dev/sr0 is write-protected, mounting read-only OK, let's see if it's mounted indeed [karol@white ~]$ mount | grep sr0 /dev/sr0 on /media/cd type iso9660 (ro) Looks fine, unmount it and eject it [karol@white ~]$ sudo umount /media/cd/ [karol@white ~]$ mount | grep sr0 [karol@white ~]$ eject /dev/sr0 eject: unable to eject, last error: Inappropriate ioctl for device Despite the error, the CD got ejected. Using eject is the only way to do it - pushing the button on the case doesn't to a damn thing ... unless I push it and try mounting again - in this case, the tray will open.
