OK, I scanned both disk images with several Amiga copy programs, and even copied the disks just fine. There are no read/write errors in the images (because that is not possible). However, the problem you see (that shows a read/write error when it is actually not) has to do with the fact that file link data is invalid. It looks like this is a case where it just so happens that the Amiga sector data checksum'd correctly. The Amiga's checksum technique is not the most robust, so it's possible that you can have invalid data checksum correctly. The checksum is the only thing we have to go by for determining if the data is really good or not. This is the first time I have seen this since back in the 90's when I had a disk do the same thing.
