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?
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 for the cd tray/drive:
*-cdrom description: DVD-RAM writer product: DVDRAM GSA-U20N vendor: HL-DT-ST physical id: 0.0.0 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/sr0 version: HX12 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=open
I fail to mount the cd manually:
$ sudo mkdir /media/t/cdrom $ sudo mount -t auto /dev/cdrom /media/t/cdrom mount: no medium found on /dev/sr0
