Maybe I got an old bug that I can not eject the CD-ROM tray from my laptop

  • 772

Laptop:DELL inspiron 15 3521 (from 2014), BIOS version A12 OS: Xubuntu 16.04.6 , Kernel: 4.4.0-141-generic. I tried everything I found on internet (almost all of them are old posts +- 5,6 years-old) with no success! The only way for me is to introduce a pin on CD drive hole to pull up the tray. The CD drive works, it's recognized by the system, I can play and so on. Is there a fix to this issue ? I attached a output from (sudo eject -rv) command. Appreciate some help. "eject -rv" output

cd xubuntu eject

  1. On my system the simpliest eject command (without arguments) ejects DVD normally.

    But with your command eject -rv you have specified implicit use of -r command and -v for verbose output (see man eject for details):

    There are four different methods of ejecting, depending on whether the device is a CD-ROM, SCSI device, removable floppy, or tape. By default eject tries all four methods in order until it succeeds.
    ...
    -v This makes eject run in verbose mode; more information is displayed about what the command is doing.
    ...
    -r This option specifies that the drive should be ejected using a CDROM eject command.

    So your device may not support this command set.

    On my system I see that eject -s works, it means using SCSI command set:

    -s This option specifies that the drive should be ejected using SCSI commands.

    You can also try with Gnome Disks (gnome-disks): find CD/DVD drive icon here, click on stop button below partitions in the right then click Eject:

    gnome-disks

    Markings:

    1. stop button with hint Unmount selected partition
    2. eject button with hint Eject this device

    Info:

    • the Device field indicates that it is /dev/sr0 (for my system)
    • clicking Eject button really eject tray, I'm running Linux kernel 4.4.0-138-generic if it matters.
    • yesterday I tried the same with internal IDE DVD-RW drive and same kernel and it worked as expected.
