I am using Ubuntu 14.04 on Thinkpad T400. I have had a problem with my cd tray for two years.
Today I pressed the button on the cd tray, and inserted a cd into the cd tray, and then I opened and read the content of the cd in Nautilus. Then I pressed again the button of the cd tray, and removed the cd from the tray, without closing the Nautilus window that opens the the cd's content. Later I closed the Nautilus window.
Now I try to press the button on the cd tray to insert a second cd into the tray, but the tray doesn't open. I also try the command line, and there seem to be some problem:
$ eject
$ eject -T
eject: CD-ROM tray close command failed: Input/output error
$ eject -t
eject: CD-ROM tray close command failed: Input/output error
How can I solve the problem?
Thanks
Update:
I used a paper clip to open the cd tray, and insert the second cd in, but after a minute, it begins to try to read the cd by making sound and flashing the light, but the cd still isn't mounted.
I guess it might not (just) be a hardware problem? Can the driver module for the cd tray be the problem? How can I test that, and make the driver module work?
I am following Discs in DVD Drive not being read. Here is the output of lshw
