It does keep adding these messages until I put the drive back in:
dmesg:
---
sr 1:0:0:0: ioctl_internal_command return code = 8000002
   : Current [descriptor]: sense key=0x0
    ASC=0x0 ASCQ=0x0
---

After all these steps (removing drive, putting it back) I was able to mount a CD
using the same drive.
