Yamaha SY-99 - GoTek USB - HxC - Bad Disk / Write Protected

Post by StudioRepairService »

Hi,

We have upgraded a Yamaha SY-99 for one of our customers. We swapped the original diskdrive for a GoTek USB floppy emulator (basic 3x 7-segment display model).

We have:

- Connected the drive using the Yamaha XS501 adapter board (which was already in the unit to connect the original floppy drive to the mainboard) (https://syntaur.com/Items.php?Item=2301)
- Set jumpers M0 + S0 (based on information i have read in a SY-77 topic)
- bought and succesfully flashed the latest HxC bootloader using a USB>TTL adapter.
- Loaded the latest firmware by USB stick (HxCFEUSB_V3_5_2_5a.UPD)
- Saved a "HXCSDFE.CFG" file in the root of the USB stick to set it in Indexed mode
- Verified that the GoTek boots up with the display text "HxC" and then "000" when the stick is inserted.
- Copied the DSKA0000.HFE file from the HxCFloppyEmulator_DosDiskBrowser application to the root of the USB stick

Now when I try to format the disk from the Yamaha SY-99 internal menu, it does detect the disk (also the green led on the GoTek lights up). It runs the formatting sequence up to 100%, but then it says Error: Write Protected. Every other disk related option to read the floppy just gives an error "Bad Disk". Then I have read somewhere that I should use the non-gated firmware using the custom firmware builder. So i did that, but that makes no difference either.

I noticed that the green led on the GoTek lights up whenever the Yamaha tries to access the disk, so there is communication. I have read somewhere that the GoTek should indicate "WR" when it's writing.. it does not do that.

Can anybody please help me (and my customer)?

Kind regards,
