I got a Chinon FB-354 Floppy Drive from an Atari ST and put this on my Amiga 500. The drive is modified as I can see. So, on the Amiga 500, when you turn the computer on, it tries two times to find a disk inside the floppy (but there is no disk inside) and then go to the HAND LOGO screen. If you put the disk, it won't load. But, if let the disk inside and restart the Amiga, the drive will read it perfectly. I think I need to enable the disk change on this floppy. Any idea where it is? I tried to find some info on the internet but nothing. Only for FB-357. Thanks!

Normaly the FB-354 work unmodified
I don't know if something more was modified, but what I found on the boad, I tried to revert and the drive was not recognized. My drive version has only 2 jumpers that is for DS0 and DS1. I just need to enable the Disc Change because the drive works when the disk is inserted before the reset.

You need to route DISKCHANGE to pin 2 and RDY to pin34 so it'll behave as an Amiga drive.
DISKCHANGE is on pin34 now (PC standard, which most likely means Atari ST standard as well)

You mean a wire from 2 to 34?

Those are the modifications that are on the drive:
This is a PCB without modifications ,

I take out the wire and on the PCB where it is cutted, I recreated but same behavior. The disk drive works after the reset, but without disc change.
