Scanned 11 more disks. The Amiga even had trouble reading a couple; tried in DF1: rather than DF0: and that did the trick. Also had to clean 2 of the disks with Isopropanol again. 11 disks scanned OK and matched; one disk needed a couple of extra rotations to read, but the Amiga also had trouble reading this disc. Total 61/61.
