It's almost working. I was able to successfully use an image configured with
4096 bytes per sector just like a regular 4KN SATA drive. What's not yet
correct is the capacity displayed by Hatari in the drive name, see
attached screenshot. Hatari does not yet use the right sector size for
the capacity calculation.

Best regards
