Thanks, I'm still not having any luck.

I got the Paint and System 2.0 images to boot my mac plus with it's internal 800k and an external 800k from my IIGS.

Both disks in the internal 400k attached to the 512K will show a happy mac for a second or two, but then it goes to a floppy with an X and ejects the disk.

Does anyone know if a 400K floppy drove will work as an internal drive for a Macintosh Plus, or as an external in the IIGS case? (A9M0106)

If I put the 400K into my Mac Plus it will ask to initialize the disk, but then it fails almost immediately and ejects the disk.
