My laptop's optical drive stopped reading discs a while ago, but I'm never given an error; I want to figure out what exactly is wrong with my optical drive.


This is a Toshiba Satellite laptop with Fedora 27. dmesg identifies the drive as MATSHITA DVD-RAM UJ8E2.


I noticed the drive stopped reading some time ago after traveling. It may have taken shock damage then, but I'm not sure since I only read CDs/DVDs occasionally (so I don't have an accurate timeline for when it stopped working).

When a disc is inserted, I hear the optical drive spin and it sounds like some data is read, but my system never acknowledges that a disc is there. Eventually, the drive spins down.

Linux commands to troubleshoot?

I found some older questions, but they were about verifying the integrity of the actual disc media, not the drive itself. Are there any tools to help me debug / figure out the point of failure on an optical drive?

    First thing which comes to mind is try cleaning the lens. If this is not it the drive might be defective. – Videonauth Nov 15 '17 at 0:32

    Given how CD drives generally work if the sensor is bad this won't be seen as a read error. It'll just do what you mention. It's the same behavior if no disc was inserted. The sensor checks for a disc nothing reads back and it assumes no disc is present. In this case the sensor is just bad. – jdwolf Nov 15 '17 at 0:34
