What you're describing seems rather like the following process (which is 
particularly convoluted if the "media" is a blank CD rather than a 
filesystem.

However,  the original poster's T520 has the CDROM builtin, so this 
seems unlikely to be related.

I suspect a hardware fault. My recommendation is firstly to try 
rebooting the machine from a live USB key (of a different distro) in 
order to eliminate the probability of a software problem. After that, 
I'd check whether the drive is physically seated correctly.
