Is there a CD/DVD disk reading test tool for Linux?

When I was using DOS and Windows I've seen quite a selection of tools to check optical disks for readability and benchmark an optical drive itself. Most of them were even visualising the results in form of a pretty chart. Are there any such for GNU/Linux OSes? I'd prefer to have a full-featured visual GUI tool, but for the particular case I've got now, I just need to check if my CD drive can read every byte of a particular heavily-scratched CD-RW disk.
