Maybe if you know something about that you could share it with us rather than dropping mysterious hints about it   Likewise if you want to dispute anything in the sites already cited, you could just come out and say it - and maybe we could get this discussion sorted before it runs to 50 pages   Regarding the CDR thing, there was an implicit assumption through this discussion that CDRs were at least as error-prone as normally pressed CDs, and hence the fact that there were zero data recovery errors under normal conditions in that particular study could reasonably be applied to this discussion. As similar results had been found elsewhere with normal audio CDs, whether or not that assumption is well-founded wasn't really relevant.

 

That's exactly what Graham and I have been saying throughout this thread since the issue of data loss first reared its ugly head
