Chinon FZ-357 Floppy Drive " Not Ready" on AX-370

I installed a PC floppy drive "Chinon FZ-357" on my AX-370 and made the needed modification (pin 7,9, and 11 +5V to red wire of the drive power cable , also pin 13 to the ground pin of the drive power cable)

The drive spins and the light is on but the head won't move forward and the drive will always gvies "Not Ready" when I try to read it using the command FILES or using the format command. The light will come on and the drive will spin but the head won't move and then I got "Drive not ready"

Anyone has an input?

I checked the capacitors and they are good. I have 3 drives and they are all behaving the same, they are all clean.

I will try that but I doubt It will work because the format function has that already and it doesn't format it. But, it detect if the disk is protected or not!

Maybe I have to remove the HD sensor on the other side because it will be looking for it and that's why it is says not ready?!

Which jumpers are set? For my Chinon FZ-354 I had to set the following jumpers:

- DS0
- MM
-TTL/C-MOS

By default it also had a jumper set for the RDY signal, which I had to remove in order for it to work in my MSX.

I will try that. There is a jumper on DC, whenever that jumper is removed and set somewhere else like setting on RDY for example it gives me I/O error instead of the not ready. I can't remember if I tried without having the jumpers on DC and RDY but on TTL/C-MOS

I will give it a try

I tried the same settings as you have, it still didn't work. It give disk I/O error, if DC jumper is not used I always get disk I/O error.
