ADDITIONAL INFORMATION

There are two drives on my system - /dev/sr0 is a Blu-Ray RW and /dev/sr1 is a DVD-RW.

The drawers will open and stay open when running either the "eject" command from the terminal or when pressing the eject button on the drive.

The drawers will open and stay open when using the remove device feature in Windows 10 so this can't be a hardware issue.
