adminThe Atari 400/800 mode is broken. This is a special case because the Atari 400/800 disks are typically single sided. I made a change to correct something else with this format and it broke the 48TPI mode. To fix this it would require a re-write of quite a bit of code. Instead of doing that I am going to release an all new version of the disk copier/imager that is track/head based instead of disk type based. This way you could imagine or copy just a single side of a disk (top or bottom). It's still compatible with the image file format though.
Until this has been released you can use the C64 mode to copy/image disks successfully with 48TPI drives. The disk format really just determines the max tracks, number of heads, etc... and nothing to do with the actual copying. Flux is flux, no matter what disk is there.

So that's complete nonsense. Because of river is river. This is not true at all. And I'll tell you why. The C64 does not use track 0. It starts with Track1 and therefore no disc can work. The Atari requires gauge 0 to boot. The C64 does not need it, because in the drive is the boot sequence needed to boot the floppy disks. Therefore, track 0 is not available on floppy disk. It always starts with track1. I can set to 40 tracks in C64 mode, but if you think you have 40 tracks as is the case with the Atari, you were wrong. There are actually 41 tracks for the Atari, since track 1 of the C64 is not seen as track 0 by the Atari. It's all moved back from track 1 to 40. With the missing track 0 there are 41. Only the track 0 is not present. So much of river is river.
