Ah.. okay. The drive was becoming ready and the read commands were retried too fast. The drive I tested on was fast enough to deliver the data but yours wasn't. Hmmm.... This is difficult. This also poses problems to live cd distros, I think. We probably need to make sr wait for device readiness. Maybe it's best to put TUR waiting in read error handling. I'll think about it.
