OF COURSE I PRESSED FIRE AFTER CHANGING DISKS. What kind of amiga user you take me for?
Yeah, I must admit I was more inclined to believe the problem was with the ADFs than with the Gotek/Firmware. Or, like you said, compatibility problems with the A600.
I always get my ADFs from Planet Emulation, I'll try the ones at the FTP later at night, thanks for the suggestion.
