I see no evidence that the "error" reported has caused any problems. The source verifies without error, and so does the copy.

 

What, exactly, doe the error mean? Is this likely to be a transient error caused by the inherent less-than-perfect electronics and the enormous amount of data being transferred? Are the "headers" re-calculated" when the new file is written? If transient, when getting such an error, does Retro re-read the data to ensure that the subsequent read does not get the error?

 

Do tell. I would like to know more about exactly what this error means. I do not want to lose confidence in the media sets with this error. OTOH, if this IS a real error, I want to re-do the operation and/or track it down.

 

Thanks
